Description

This invention relates generally to shoes, and more particularly to golf shoes having a lace tightening system. The shoe upper includes various lace guides separated by gaps. The laces are threaded through these guides and can be tightened or loosened with a rotary dial attached to the shoe. A lacing system can be used to close the instep area to secure the shoe and provide a comfortable fit. The midsole provides cushioning to the shoe. The outsole preferably includes a plurality of traction members to provide good stability and contact with the ground.

Both professional and amateur golfers use specially designed golf shoes today. Golf shoes typically include an upper portion, an outsole portion, and a midsole connecting the upper to the outsole. The upper has a traditional shape for inserting the user's foot, thus covering and protecting the foot in the shoe. The upper is designed to comfortably fit the contours of your foot. The midsole is relatively lightweight and provides cushioning to the shoe. The outsole is designed to give golfers stability and traction. The bottom surface of the outsole may include spikes or cleats designed to engage the ground through contact with and penetration into the ground. These elements help golfers improve foot stability and traction as they walk and play the course.

Golf shoe manufacturers have developed shoes with uppers that include uppers with typical lace tying systems. Laces are used to control the size of the mouth opening in the instep through which the foot is inserted. In such conventional shoes, the lace is threaded through a series of eyelets on opposite sides of the upper of the shoe. The lace is threaded through the eyelets in a zigzag pattern over the tongue of the shoe. When the golfer inserts his foot into the instep and pulls on the lace to "tie the shoe", the eyelets are pulled together and the instep area is closed.

In recent years, athletic shoe manufacturers have developed lace tightening systems that do not use conventional laces, as described in patent literature. For example, U.S. Pat. No. 5,511,325 (Hieblinger) uses a central rotary closure located on the upper heel and at least one tightening element having a tightening section extending from the central rotary closure toward each side of the shoe. Athletic shoes are disclosed. The tightening sections are joined by coupling elements comprising at least one strap extending from each tightening section or coupling element over the instep and/or by the arch to other tightening sections or coupling elements.

U.S. Pat. No. 9,375,052 (Krueger) discloses a sports shoe having a sole connected to an upper shoe portion having two adjacent tension sections in instep regions separated by a gap. The lacing system is arranged to allow the shoe to be laced on the wearer's foot by pulling one tensioning section against the other. The lacing system includes a rotating central closure system attached to the tongue of the shoe. According to the Krueger '052 patent, a running shoe can be made with this lacing system. For golf applications, the Krueger '052 patent discloses that the left and right shoes can be designed differently with respect to the implementation of the tension elements.

U.S. Pat. No. 9,462,851 (Baker et al.) discloses a shoe with cables disposed between an upper and a sole plate. The upper includes a flexible body and an exoskeleton covering a portion of the flexible body of the instep. Because the cables are attached to the exoskeleton, an increase in cable tension tightens the exoskeleton against the wearer's foot. According to the Baker '851 patent, the cable tensioning system is particularly suitable for turf shoes such as soccer and football cleats. The Baker '851 patent also discloses running shoes, tennis shoes, cross-training shoes, walking shoes, and hiking boots.

U.S. Pat. No. 9,491,983 (Rushbrook) discloses a shoe having a sole structure with a gap extending longitudinally through the sole structure. A tension member extends through the sole structure and across the gap, such that pulling the tension member contracts the gap and pulls opposite sides of the sole structure together. Contraction of the sole structure draws the upper down onto the foot, tightening the upper around the foot. The Rushbrook '983 patent discloses suitable shoes such as hiking boots, soccer shoes, soccer shoes, sneakers, running shoes, cross training shoes, rugby shoes, basketball shoes, baseball shoes, and the like.

A need remains for an improved golf shoe having a lace tightening system that can be used to close the instep around the contours of the foot to provide a comfortable fit. A lacing system must secure the foot in the shoe while providing a comfortable, smooth fit. Also, the lace tightening system should be comfortable for all golfers. Some golfers prefer a snug fit in their shoes. These golfers want shoes that closely conform to the contours of their feet. Other golfers prefer a looser fit so that the foot can move more easily in the shoe. In both cases, golfers want stable shoes with a comfortable, smooth fit. Shoes need to hold and support the medial and lateral and heel areas of a golfer's foot as he shifts his weight when making a golf shot. The shoe should be non-slip and provide good stability so that the golfer can maintain balance when swinging the club.

Also, one drawback of some conventional golf shoes is the loss of flexibility of the shoe, although these shoes can help provide good stability and traction to the golfer. Some traditional golf shoes are relatively stiff—they provide a stiff platform but do not provide the golfer with the necessary flexibility. As explained further below, when a golfer swings the club and transfers weight to his or her feet, great forces are exerted on the feet. The shoe should provide a stable platform for the golfer to swing through, but the foot should also allow some flexing. Golfers need the sides to feel comfortable in their shoes.

The shoe of the present invention has a unique upper construction with a lace tightening system that assists in holding and supporting the golfer's foot within the shoe. The shoe includes a closure system that helps hold the foot securely within the shoe and provides the golfer with a stable platform. At the same time, the closure system provides the golfer with a comfortable fit. The shoes are comfortable and natural. The shoe provides golfers with high structural support and traction, yet is comfortable and natural to wear. The shoe can flex the foot and move as needed. The shoe provides stability and power without sacrificing comfort, flexibility, and other golf performance characteristics.

U.S. Pat. No. 5,511,325 U.S. Pat. No. 9,375,052 U.S. Pat. No. 9,462,851 U.S. Pat. No. 9,491,983

The first and second lower race guides are attached to the lower tip.

The upper further has a lateral lace channel extending from the rearfoot region along the lateral side of the upper and a medial lace channel extending from the rearfoot region along the medial side of the upper. The channels are adapted to accommodate the races, which exit the outer channel to the outer surface and pass through the upper and lower race guides and through the third upper race guide and into the inner channel. . The lace forms a continuous loop such that the lace extends along the lateral and medial sides of the upper and around the instep region. As the lace is tightened, the power shroud is pulled toward the lower tip to tighten the shoe around the foot.

In one example, there is a skeletal frame that overlies the upper and has a plurality of rib members extending upwardly from the midsole that join together to form openings to form an A-frame shaped structure. . The skeletal frame extends over the lateral side and the medial side of the upper to form an A-frame shaped structure over the lateral side and the medial side of the upper. The skeletal frame is preferably manufactured from a thermoplastic polyurethane material.

Further, in another embodiment, the shoe comprises a first lace tightening system, the first lace tightening system having a first lace and a first lace tightening assembly, and a second lace tightening system. and said second race tightening system having a second race and a second race tightening assembly.

Referring to the drawings, like reference numerals are used to indicate like elements, and with particular reference to Figure 1, one embodiment of the golf shoe (10) of the present invention is shown. The shoe (10) includes an upper (12) portion and an outsole (16) portion, with a midsole (14) connecting the upper (12) to the outsole (16). It is understood that the view shown is of the right foot shoe and the components of the left foot shoe are mirror images of the right foot shoe. It should also be appreciated that shoes can be manufactured in a variety of sizes and therefore the sizes of the components of the shoe can be adjusted according to the size of the shoe.

[structure]
The upper (12) is traditionally shaped and made from standard upper materials such as natural leather, synthetic leather, knits, nonwovens, natural fibers, synthetic fibers, and the like. For example, breathable, mesh, and synthetic fiber fabrics made from nylons, polyesters, polyolefins, polyurethanes, rubbers, foams, and combinations thereof can be used. Materials used in the construction of the upper are selected based on desired properties such as breathability, durability, flexibility and comfort. In one preferred example, the upper (12) is made of mesh material. The materials of the upper are stitched or bonded together to form the structure of the upper. Referring to Figures 1-3, the upper (12) generally includes an instep region (18) with a throat opening (20) for insertion of the foot. The upper includes a vamp (19) and a tongue member (22) to cover the front of the foot. The instep region includes a power shroud or shield (24) that covers the tongue member (22). The upper (12) may include a fox (26) and optional gill strip (28) extending from the rear region of the instep region (18). Laces (30) are used to tighten the shoe around the contours of the foot. Various race tightening systems for tightening and locking the race in place and loosening the race (30) are further described below. The above-described upper (12) shown in Figures 1-3 is but one example of uppers that may be used in the shoe construction of the present invention, and that other uppers may be used without departing from the spirit and scope of the present invention. Please understand.

The midsole (14) is relatively lightweight and provides cushioning to the shoe. Midsole (14) can be made from standard midsole materials such as, for example, expanded ethylene vinyl acetate copolymer (EVA) or polyurethane. In one manufacturing process, the midsole (14) is molded over and around the outsole. Alternatively, midsole (14) is molded as a separate piece and then stitched, glued, or otherwise suitable secured using standard techniques known in the art. It may be joined to the top surface (not shown) of the outsole (16) by means. For example, midsole (14) may be heat pressed and bonded to the top surface of outsole (16). The above-described midsole (14) shown in Figures 1-3 is but one example of a midsole that can be used in the shoe construction of this invention, and other midsoles may be used without departing from the spirit and scope of this invention. Note that it is possible to

Generally, the outsole (16) is designed to provide stability and traction to the shoe. Referring to FIG. 4, the bottom surface of outsole (16) includes a plurality of traction members (32) to help provide traction between the shoe and grass on the course. The outsole (16) and the bottom surface of the traction member (32) can be made of any suitable material such as rubber or plastic, and combinations thereof. Thermoplastics such as nylons, polyesters, polyolefins and polyurethanes can be used.

The bottom surface of the outsole (16) is configured to contact the ground during golf play. The golf shoe preferably includes traction projections of various shapes projecting from the bottom surface of the outsole. The traction protrusion (32) can be of various shapes and sizes. Traction member (32) may be of any suitable shape including, but not limited to, rectangular, triangular, square, spherical, star, diamond, pyramid, arrow, bar, or cone. Also, the height and area of the traction members (32) may be the same or different. The traction member (32) is designed to engage the ground and increase the contact area with the ground. This helps golfers improve foot traction on the turf as they walk the course and play rounds. The above-described outsole (16) shown in FIG. 4 represents only one example of an outsole that can be used in the shoe construction of this invention, and other outsole designs may be used without departing from the spirit and scope of this invention. Note that you can

As further shown in FIG. 4, the bottom surface of the outsole (16) may further include spikes or cleats (34). Attached cleats provide additional traction between the shoe and the ground. If such spikes or cleats (34) are present, they are preferably releasably secured to sockets (receptacles) (35) of the outsole (16). The outsole (16) may further include flexion channels (36) extending laterally along the outsole. The structure and functionality of the outsole (16) shown in Figure 4 are described in further detail below.

Basically, the anatomy of the foot can be divided into three bony regions. The hindfoot region typically includes the ankle (talus) and heel (calcaneus) bones. The midfoot includes the cuboid, cuneiform, and navicular bones that form the longitudinal arch of the foot. The forefoot includes the metatarsals and toes. The outsole (16) generally comprises a metatarsal (forefoot) portion (21) positioned under the wearer's metatarsal bones, the arch (metatarsal) portion (21) generally positioned under the arch of the wearer's foot. It includes a portion (23) and a calcaneus (hindfoot) portion (25) which is generally positioned under the wearer's calcaneus. The outsole (16) comprises a top (upper) surface (not shown) and a bottom (lower) surface (27). The midsole (14) is joined to the upper surface of the outsole (16).

[upper]
Referring back to Figure 1, portions of the upper (12) generally include an instep region (18) with a throat opening (20) for insertion of the foot. The instep region (18) includes a tongue member (22) and a power shroud (24) extending from the medial edge or side (38) of the upper and covering the tongue member (22). The power shroud (24) extends over the instep region (18) toward the sides (41) when the race (30) is tightened via the race tightening system (60), as further described below. be pulled. A lower tip (40) extends upwardly from an outer edge (42) of the portion of the upper (12). As shown in Figures 2-3, in this example the power shroud (24) has a Y-shaped configuration. However, it should be noted that the power shroud (24) and lower tip (40) may have other suitable shapes. 1-3, the upper (12) is made of engineered mesh material with ribs (13) and the power shroud (24) also includes matching ribs (15) for aesthetically pleasing lines. and fashionable designed upper (12). The bottom chip (40) can be made of any suitable material, for example thermoplastic polyurethane (TPU). The power shroud (24) also includes i) a first upper race guide (44) and ii) a second upper race guide (46). The lower tip (40) also includes a first lower race guide (48) and a second lower race guide (50).

Upper (12) further includes an outer race channel (52) extending along the outer side of the upper. Lace (30) is disposed in channel (52) to extend from lace tightening assembly (60) in heel region (17) to instep region (18). The lace (30) can be made of any material known in the art, such as metal, fabric, for example. For example, lace (30) can be made of thread, cord, rope, string, fiber, filament, strand, cloth, webbing or other fibrous material. Lace can be made using polyamide (nylon), aramid such as Kevlar™ fiber, polyester, polyurethane, polypropylene, polyethylene, and the like (30). In other examples, the lace (30) can be made from metal materials such as metal, glass, carbon fiber, carbon fiber composites, or metal wire or cable. A stainless steel race (30) can be used. Preferably, the race (30) is made of wear-resistant, durable material. A combination of materials can also be used. For example, lace (30) can be made of stainless steel, nylon, polyester, polyurethane, polypropylene, and/or polyethylene. Other materials that can be used to make the lace (30) include Dyneema(tm) composite fabric, which is a laminated fabric constructed from ultra high molecular weight polyethylene (UHMWPE) fibers. Monofilaments, fibers, and films can also be used to form the lace (30).

The lace (30) extends through the eyelet guide (54) to the heel area (17) where the lace tightening assembly (60) is preferably attached. As the race (30) is tightened, the power shroud (24) is pulled downward so that it at least partially covers the instep region (18). Preferably, when the power shroud (24) is tightened it covers the entire instep area (18). In this way the shoe (10) is securely and comfortably attached around the foot. The tightening of the race (30) as it is pulled through the race guides and the forces exerted on the power shroud (24) and shoe (10) are further described below.

[Race Guide]
As shown in FIGS. 1-2, the first upper race guide (44) attached to the power shroud (24) is oriented in an angled position. The first upper race guide (44) may be attached to the power shroud (24) by stitching, adhesive, or other suitable fastening means. The lace (30) extends from the lace tightening assembly (60) in the heel area (described further below) and exits the trumpet or eyelet guide (54). The race (30) then enters a first upper race guide (44) at an entry point and exits the race guide (44) at an exit point. The lace guide (44) thus helps guide the path of the lace (30) around the upper of the shoe.

After exiting the first upper race guide (44) at the exit point, the race (30) passes downward and enters the second lower race guide (50) at the entry point. The race travels through a second lower race guide (50) and then exits the race guide (50) at an exit point. After exiting the second lower race guide (50), the race is threaded upward into the second upper race guide (46) where it enters the guide (46) at the entry point. The race (30) then travels through a second upper race guide (46) and exits the race guide (46) at an exit point. The race (30) then passes downwards and crosses itself only when entering the first lower race guide (48) at the entry point. As shown in FIG. As shown in FIG. 1, this area can be referred to as the first crisscrossing zone (“X”). The race (30) travels through a first lower race guide (48) and then exits this race guide (48) at an exit point. The race (30) then extends upward and traverses itself again until its path terminates at the end plate (56) attached to the power shroud (24). This area is called the second crisscrossing zone ("Y"). The race guides and end plates can be made of tightly woven fabric, molded plastic, metal, or other suitable material designed to conform under tension.

A crisscross race (30) slidably engages the upper and lower race guides and crosses a gap (57) located between the power shroud (24) and the lower tip (40), thereby providing power It holds the shroud (24) there. As the race (30) is tightened via the race tightening assembly (60), the power shroud (24) is pulled downward as represented by arrow A. An angular force is applied to the power shroud (24) pulling the shroud (24) downward in the direction of arrow A. The low friction of the race guide allows the race (30) to be pulled smoothly and firmly from the guide. The length between the entry and exit of the race guide and the path of the race (30) will be further described below.

In different embodiments, the length of power shroud (24) may vary. For example, in some embodiments, the length (L1) of power shroud (24) may range from about 0.5 to about 2.5 inches. In one example, the power shroud length (L1) is approximately 1.25 inches. In general, the power shroud (24) typically covers about 10% to about 80% of the surface area of the shoe upper (12).

The width of the power shroud (24) may also vary. For example, in some embodiments, the width (W1) of power shroud (24) may range from about 0.50 to about 2.50 inches. In one example, the width (W1) of the power shroud is approximately 1.75 inches. The width of the power shroud (24) should be greater than the width of the tongue member in the upper region (18). Thus, the power shroud (24) extends laterally across the tongue member (22).

The angular force applied to the power shroud (24) will also depend on the length and position of the race guide. In Figures 1-1 the race guide is shown in an angled position. The upper race guides (44,46) are substantially parallel to the lower race guides (48,50). As previously discussed, a race (30) enters a given race guide at an entry point and exits the race guide at an exit point. The length between the race guide entrance and exit may be variable. Race guides can be made of tightly woven fabric, molded plastic, metal, or other suitable material designed to conform under tension. Typically, the length of the race guide ranges from about 5mm to about 50mm. In one example, the length of the race guide is about 20mm.

The angular force applied to the power shroud (24) will also depend on the gap between the race guides. As previously discussed, the race (30) exits the first upper race guide (44) at an exit point before entering the second lower race guide (50) and then the second lower race guide (50). exit. The gap (Ga1) between the first upper race guide (44) and the second lower race guide (50) generally ranges from about 0.100 to about 2.00 inches, preferably about 0.100 inches. .125 to about 1.750 inches.

After exiting the second lower race guide (50), the race (30) enters the second upper race guide (46). The gap (Ga2) between the second lower race guide (50) and the second upper race guide (46) generally ranges from about 0.100 to about 2.00 inches, preferably about It ranges from 0.125 to about 1.750 inches. The race (30) then traverses itself and enters the first lower race guide (48) at the entry point. The gap (Ga3) between the second upper race guide (46) and the first lower race guide (48) is from about 0.100 to about 2.00 inches, preferably from about 0.125 to about 1.0 inch. It may be in the range of 750 inches. The race (30) then exits the first lower race guide (48). Cross yourself again. It then dies with an end plate (56) attached to the power shroud (24). The gap (Ga4) between the first lower race guide (48) and the end plate (56) ranges from about 0.100 to about 2.00 inches, preferably from about 0.125 to about 1.750 inches. can be

[channel]
1 and 2, as discussed above, upper (12) includes an outer lace channel (52) that extends laterally from heel region (17) to instep region (18). A race (30) is disposed within the channel (52) and forms a loop between the power shroud (24) and the lower tip (connection piece) (40) as it exits the channel. Outer race channel (52) includes a plastic tube (not shown) for holding and guiding race (30) through its passage within channel (52). The race (30) exits the race channel (52) through an eyelet guide (54).

[Lace tightening system]
Any suitable lace tightening assembly (60) may be used in accordance with the present invention. An example of a suitable lace tightening system is available from Boa Technology, Inc. (Denver, CO 80216); FITGO Technology Co.; , Ltd. , Technology Part GuShu Industrial BaoAn, Shenzhen District, China; ATOP Racing System, Yu Chen Plastic Ent. Co. Ltd. , Taichung, Taiwan; and QUICKFIT Lacing Systems, Click Medical (Steamboat Springs, Colorado, Colo. 80487). Other lace tightening systems may also be used in accordance with this invention. Spool (reel) systems are described in the patent literature and such systems can be used in accordance with the present invention. For example, such spool tightening systems are disclosed in US Pat. No. 7,591,050 (Hammerslag) and US Pat. No. 6,289,558 (Hammerslag), the disclosures of which are incorporated herein by reference. incorporated here. The lace tightening assembly (60) can be located anywhere in the heel area and is preferably attached to the shoe upper (12) in the center of the heel area as shown in FIG. In another embodiment, the lace tightening assembly (60) can be placed on the tongue member. In yet another embodiment, assembly (60) can be located in a remote area on shoe upper (12). FIG. 1 shows one embodiment of a race tightening assembly (60) that can include a rotatable dial (62) covering a spool (not shown) located within a housing (not shown). The housing includes a flange that allows the housing to be sewn or riveted to the shoe upper (12).

The race (30) is fed to a race tightening assembly (60) and wound onto a spool. Since the spool is rotatably attached to the shoe upper (12), turning the rotary dial (62) in a first direction winds more lace segments onto the spool. This reduces the effective length of the race (30). Turning rotary dial (62) in a second direction unwinds the lace segment from the spool, increasing the effective length of lace (30). In some embodiments, the first direction is clockwise and the second direction is counterclockwise. In another embodiment, the first direction is counterclockwise and the second direction is clockwise.

Turning the dial (62) shortens the length of the lace (30) by wrapping the lace around the spool as described above. Tightening the race (30) pulls the power shroud (24). This is because the races are threaded through eye guide (54) and race guides (44, 46, 48, and 50) attached to power shroud (24) and lower tip (40). This tightening of the lace (30) tightens the power shroud (24) downward, in the direction of arrow A, and toward the outsole (16).

To loosen the lace (30), a human hand pulls the dial (62) apart and this action unties the lace. Pull the dial away to quickly release the lace tightening system. The effective length of the lace (30) is lengthened and the slack is returned to the lace. This slackened lace (30) allows the power shroud (24) and shoe upper (12) to loosen so that the foot can be pulled out more easily.

A suitable lace tightening assembly (60) is available from Boa Technology, Inc. (Denver, Colorado, CO 80216), but are not limited to these. As shown in FIGS. 1-4, the lace tightening assembly (60) is attached to the heel region of the shoe upper (12). In one embodiment, the attached dial (62) is pushed inwards first to engage the lace tightening system. The dial (62) is then rotated clockwise to tighten the lace (30). To loosen the lace (30), rotate the dial (62) counterclockwise. In this way the tension of the race (30) can be adjusted. The tension can be increased or decreased in small increments. In a second embodiment, the dial (62) is pushed inwards to engage the tightening system. The dial (62) is then turned clockwise to tighten the lace (30). The dial (62) can be pulled out to quickly release the tightening system and loosen the lace (30). In a third embodiment, dial (62) is rotated counterclockwise to tighten lace (32). To loosen the lace (30), rotate the dial (62) clockwise.

[Outsole]
Referring to Figure 4, there is shown one embodiment of an outsole (16) that can be used with the shoe (10) of the present invention. Outsole (16) also includes a lateral side (66) and a medial side (68). A lateral side (66) and a medial side (68) extend through each foot region (21, 23, and 25) and correspond to opposite sides of the outsole (16). The lateral side or edge (66) of the outsole is the side corresponding to the lateral region of the wearer's foot. The lateral edge (66) is the side of the wearer's foot that is generally farthest from the wearer's other foot (ie, the side closest to the fifth toe). The medial side or edge (68) of the outsole is the side corresponding to the medial area of the wearer's foot. The medial edge (68) is generally the side of the wearer's foot that is closest to the wearer's other foot (ie, the side closest to the big toe). The lateral and medial sides extend around the perimeter or perimeter (70) of the outsole (16) from the outsole's leading edge (72) to its trailing edge (74). As shown in Figure 4, the outsole (16) is positioned generally under the wearer's metatarsal or forefoot region (21), typically under the wearer's arch of the foot. It includes an arch or metatarsal region (23) where it is located, and a calcaneus or hindfoot region (25) which is generally located below the wearer's calcaneus.

Regions, sides, and areas of the outsole as described above are not intended to distinguish the exact location of the outsole. Rather, these areas, sides and areas are intended to represent general locations of the outsole. The upper (12) and midsole (14) also include such regions, sides and zones. Each region, side, and section may include a front portion and a rear portion.

As further shown in FIG. 4, the bottom surface of the outsole (16) may further include spikes or cleats (34). Attached cleats provide additional traction between the shoe and the ground. If such spikes or cleats (34) are present, they are preferably releasably secured to sockets (receptacles) (35) of the outsole (16). The spike (34) can be easily inserted and removed from the receptacle (35). Typically, spike (34) may be secured to receptacle (35) by inserting it and then slightly twisting it clockwise. The spike (34) can be removed from the receptacle (35) by twisting it slightly counter-clockwise. Outsole (16) may include any suitable number of cleats, and the cleats may be arranged in a wide variety of patterns. Since most golf courses require golfers to use non-metallic cleats, the cleats are preferably made of a plastic material. The outsole (16) may also include one or more flexion channels (36) extending laterally or longitudinally therethrough. The flexion channels (36) are preferably positioned to provide the outsole (16) with a flexion area that accommodates the natural flexion of the foot during walking.

Preferably, the outsole (16) has a plurality of flexion channels (36), each flexion channel extending generally laterally from the lateral edge (66) or medial edge (68) to the interior region (75) of the outsole. direction. The tortuous channel (36) is substantially linear with a relatively wide end and a relatively narrow opposite end. That is, the channel (36) is generally tapered and shaped like a spire. A rigid base material surrounds the flexion channel (36). As noted above, the outsole (16) preferably includes multiple receptacles for attaching and removing multiple spikes (34). As shown in Figure 4, the receptacle (35) is positioned adjacent to the sharp end of the bend channel (36).

A stiff base material (80) provides stiffness for support and stability, while flex channels (36) allow the outsole (16) to flex as the golfer walks and swings. At least one flexion channel (36) may extend from the lateral edge to a point within the interior region of the outsole adjacent to the receptacle. At least one flexion channel (36) may extend from the medial edge to a point within the interior region of the outsole adjacent to the receptacle.

As mentioned above, the metatarsal (21), arch (23), and calcaneal regions (25) include flexion channels (36), which are voids within the outsole (16) and out It extends across the sole (16). Each spire-shaped flex channel (36) extends laterally from the outer edge of the outsole to the interior region (75) of the outsole (16). The spire-shaped winding channels (36) are substantially parallel to each other. The pointed end of the spire-shaped bend channel (36) adjoins the receptacle (35) where it terminates in the interior region.

The flex channel (36) allows the outsole (16) to flex and flex as the golfer walks or swings the club. The flexion channel (36) generally extends along an interior region (75) between the medial edge (68) and the lateral edge (66) of the outsole (16). In the embodiment shown in Figure 4, the outsole (16) includes four flexion channels (36) across the metatarsal portion (21) and two flexion channels (36) across the arch portion (23). , two flexion channels (36) across the calcaneus part (25). Note, however, that the total number of flexion channels (36) may vary depending on the desired flexibility of outsole (16) and size of shoe (10). Likewise, the depth, width, and shape of flexion channels (36) may vary depending on the desired flexibility of outsole (16).

Still referring to FIG. 1, a stiff base material (80) extends across the outsole (16) and surrounds the flex channel (36). A stiff base material (80) provides stiffness and stability to the outsole (16). The rigid substrate (80) may be a material such as thermoplastic polyurethane and may have a hardness of at least 80 Shore A. The rigid substrate (80) does not constitute the entire outsole (16) of the shoe (10). . Rather, as previously discussed and shown in Figure 4, the flexion channel (36) forms part of the outsole of the shoe. Flex channel (36) is made of a relatively soft material such as EVA. In one preferred embodiment, the flex channel (36) comprises the same EVA or other material used to make the midsole (14) of the shoe. The exposed midsole (14) region of the shoe forms a flexion channel (36). The midsole (ie flex channel) is clearly visible to a person looking at the outsole (16) of the shoe. As previously discussed, the outsole (16) also has a series of traction elements or members (32) and spikes (34) extending from the rigid base material (80), which provide traction to the outsole (16). and the ground.

The above-described outsole (16) shown in FIG. 4 represents only one example of an outsole that can be used in the shoe construction of this invention; other outsoles are possible without departing from the spirit and scope of this invention. Note that you can use For example, other suitable outsoles include US Patent Application Publication Nos. 2020/0077734-A1 and US Patent Application Publication No. 2020/0146389-A1 (Bidal); US Patent Application Publication No. 2020/0046072-A1 (Bento). and structures described in US Pat. Nos. 9,999,275 and 10,595,585 (Bacon).

[Force applied to the foot]
During normal golf play, golfers make shots with a wide variety of clubs. As a golfer swings the club and shifts his weight as he makes a shot, his feet absorb tremendous forces. Often, when right-handed golfers are addressing the ball, their right and left feet are in a neutral position. As the golfer makes the backswing, the right foot pushes down on the medial forefoot and heel area, and as the right knee remains tucked in, the right foot exerts torque on the ground to resist rotation of the outer foot. Following a shot, the golfer's left shoe rolls from the inside of the left foot to the outside of the left foot. Meanwhile, their right shoe simultaneously bends to the front foot and rotates internally as the heel rises.

As previously discussed, considerable pressure is applied to the foot at various stages of the golf shot cycle. In this invention, the lace tightening system helps provide support and stability to the lateral and heel areas of the foot. As shown in Figures 1-4, the lace extends only along one side of the shoe, yet still provides an optimal closure system and provides a comfortable fit. There is only one strand of lace. That is, a single lace (30) is shown in Figures 1-4 and extends along only the lateral side of the shoe upper (12), the upper running from the heel region (17) to the instep region. It includes an outer race channel (52) extending laterally to (18). A race (30) is disposed within the channel (52) and upon exiting the channel forms a loop between the power shroud (24) and the lower tip (40) before terminating in a termination plate (56). do. In another example, the laces can be threaded so that they extend only along the medial side of the upper (12).

The lace tightening system (60) of the present invention helps to hold and support the medial and lateral sides and heel area of the golfer's foot as the golfer makes shots and shifts his weight. The foot is held downwards and backwards by a lace tightening system (60). Therefore, golfers have better stability and balance when making shots. This supportive and contoured fit assists the golfer in all phases of the game, including walking the course. Although the shoe (10) fits snugly around the foot, the shoe is not overly stiff. The shoe (10) allows some movement of the foot inside the shoe. That is, the shoe allows some movement of the foot, but the movement of the foot is controlled. The lace tightening system of this invention helps provide a structured, smooth and comfortable fit. The lace tightening system helps control foot movement by applying force to the medial and lateral sides as well as the heel area. Shoes hold and support the foot without sacrificing flexibility. The shoe thus provides a snug yet comfortable fit. In one embodiment, the tension of the race as it passes through the various race guides is substantially the same. In other embodiments, the tension can vary. By adjusting the laces, you can apply a substantially even force against the upper of the shoe. The system of the present invention distributes lateral, medial, and downward clamping forces along the length of the foot. Thus, the shoe is evenly tightened against the wearer's foot. This helps prevent pressure points from developing on the wearer's foot. Additionally, the lacing system can be incrementally adjusted to tighten or loosen the laces as desired by the wearer of the shoe.

[Other shoe structures]
The shoe structure described above generally includes: a) an upper (12); b) an outsole (16); c) a midsole (14) connecting the upper (12) and the outsole (16); includes a power shroud (24) that extends outward (41) beyond the instep region (18) when the race (30) is tightened via the race tightening system (60). Note that the upper also includes a lower tip (40) and that this shoe construction is but one example of the shoe construction of the present invention. As discussed earlier, the unique upper construction and lace tightening system help provide golfers with greater stability and balance on a variety of surfaces. However, it should be noted that other upper and shoe constructions may be used without departing from the spirit and scope of the present invention.

For example, referring to Figures 5-8, there is shown a second embodiment of a shoe upper (12) having a similar construction to the shoe upper shown in Figures 1-4. In this example, race (30) travels through a first lower race guide (48) and then exits this race guide (48) at an exit point similar to the race path described above. The race (30) then extends upwards and crosses a second time ("Y"-second crisscrossing zone). However, instead of race (30) terminating its path at an end plate (56) attached to power shroud (24) as shown in FIGS. continues over the upper region (18) and is attached to the upper trailing edge of the power shroud (24) and threaded through a third upper race guide (53) adjacent the tongue member (22).

Thus, as shown in Figures 5-8, in this embodiment the same laces (30) run along both sides of the shoe. That is, the single lace (30) shown in Figures 5-8 extends along the outer and inner sides of the shoe upper (12). The lace tightening system, in which the lace (30) is configured to extend over the instep region (18) with outer and inner paths, provides a particularly stable closure system. In this example, the upper (12) includes an outer lace channel (52) and an inner lace channel (55) extending laterally from the instep region (18) to the heel region (17). The race thus exits the outer race channel (52) and is threaded through the upper and lower race guides on the outer side of the upper (12) as described above. The same race (30) then passes through the third upper race guide (53) to the inner side where it enters the inner race channel (55). The medial lace channel (55) extends laterally from the instep region (18) back to the heel region (17). There, the lace is unwound onto the spool of the lace tightening assembly (60). The lace (30) thus forms a continuous loop such that the lace extends along the lateral and medial sides and around the heel region of the shoe upper (12). Adjusting the lace (30) provides substantially uniform application of force to the upper of the shoe on both the lateral and medial sides. The shoe is evenly tightened against the wearer's foot. This helps prevent pressure points on the wearer's foot.

Referring to Figures 9 and 10, in a third embodiment, the shoe upper (12) has an "A-frame shape" construction (63) extending upward from the midsole (14) that provides additional stability and support. It has a unique design with a skeletal frame with The A-frame skeletal structure (63) extends along the lateral side (41) and medial side (38) of the shoe (10). The A-frame skeletal structure is a single unitary structure in the form of a triangle as shown in lateral side view (Fig. 9) and medial side view (Fig. 10) having three surfaces or segments (31a, 31b, and 31c) is. These segments are joined together to form an aperture (37) as shown in FIGS. The A-frame skeletal structure (63) helps provide structural support and stiffness while remaining lightweight. A relatively stiff and durable A-frame skeletal structure (63) overlays the upper (12) and helps provide stiffness and stability to the shoe (10). The A-frame skeletal structure (63) is preferably made of thermoplastic polyurethane (TPU). Other suitable durable materials can be used. The A-frame skeletal structure (63) extends to the upper (12) and thus provides a stable platform in conjunction with the power shroud (24). The A-frame skeleton (63) complements the power shroud (24) well. Both structures work together to enhance the support and stability features of the shoe.

In this embodiment, the race (30) is threaded through upper and lower race guides in the same manner as shown in Figures 1-4. Specifically, the first upper race guide (44) attached to the power shroud (24) is oriented in an angled position. The first upper race guide (44) may be attached to the power shroud (24) by stitching, adhesive, or other suitable fastening means. The lace (30) extends from the lace tightening assembly (60) in the heel area (17) and exits the trumpet or eyelet guide (54). The race (30) then enters and exits the first upper race guide (44) at the entry point. After exiting the first upper race guide (44) at the exit point, the race (30) passes downward into a second lower race guide (50) attached to the outer side (41) of the upper. . The race (30) travels through a second lower race guide (50) and then exits this race guide (50) at an exit point. After exiting the second lower race guide (50), the race is threaded upward into the second upper race guide (46) where it enters the guide (46) at the entry point. The race (30) then travels through the second upper race guide (46) and exits this race guide (46).

The race (30) then passes downwards and crosses itself for the first time as it enters a first lower race guide (48) attached to the outer side (41) of the upper. As shown in FIG. 9, this area can be referred to as the first crisscrossing zone (“X”). The race (30) travels through a first lower race guide (48) and then exits this race guide (48) at an exit point. The race (30) then extends upward and traverses itself again until its path terminates at the end plate (56) attached to the power shroud (24). This area is called the second crisscrossing zone ("Y"). As shown in Figures 9-10, the lace (30) extends only on one side of the shoe, yet still provides an optimal closure system and provides a comfortable fit. There is only one strand of lace. That is, a single lace (30) extends only along the lateral side of the shoe upper (12), as shown in Figures 9-10. In another example, the lace can be threaded so that it extends only along the medial side of the upper (12).

Referring to Figures 11 and 12, a fourth embodiment of shoe (10) is shown where there are two lace tightening assemblies (60a, 60b) and two power shrouds (24a, 24b). In this embodiment, upper (12) generally includes an instep region (18) with an opening (20) for foot insertion. The upper region (18) includes a tongue member (22) and two power shrouds (24a, 24b). A first power shroud (24a) extends from the medial edge (38) of the upper (12), covers the tongue member (22), and extends to the lateral side (41). Tightening the laces (30) pulls the first power shroud (24a) downward to cover the instep area (18). The first power shroud (24a) is pulled over the instep region (18) toward the outboard side (41) when the race (30) is tightened via the race tightening system (60a). In this way the shoe (10) is securely and comfortably attached around the foot. As shown in FIGS. 11-12, the first power shroud (24a) also includes i) a first upper race guide (44). A second power shroud (24b), on the other hand, extends from the outer side (41) of the upper (12), covers the tongue member (22), and extends to the inner side (38) (Fig. 12). The second power shroud (24b) also includes i) a second upper race guide (46). Additionally, a first lower race guide (48) is shown secured to the medial side of the upper (12) (Fig. 12).

As shown in Figures 11-12, the first upper race guide (44) attached to the first power shroud (24a) is oriented in an angled position. The first upper race guide (44) may be attached to the first power shroud (24a) by stitching, adhesive, or any other suitable fastening means. The first race (30) exits a first race tightening assembly (60a) attached to the upper (12) and enters a first upper race guide (44) at an entry point and then into this race guide. Exit (44). The race guide (44) has low friction, which allows the race (30) to be pulled smoothly and firmly through the guide (44). The first upper lace guide (44) in this embodiment of shoe (10) may have the same dimensions as the lace guides discussed above.

After the first race (30) exits the first upper race guide (44) at the exit point, it is threaded down and back into the same first race tightening system (60a). As previously discussed, the race tightening assembly (60a) may include a dial (62a) overlying a spool (not shown) for winding a race disposed within the housing. In one embodiment, dial (62a) is pushed inwards first to engage lace tightening system (60a). The dial (62a) is then rotated clockwise to tighten the lace (30). As the first race (30) is tightened, the first power shroud (24a) is pulled downward as represented by arrow B. This is an angular force acting on the power shroud (24a). Rotate dial (62a) counter-clockwise to loosen lace (30). In this way the tension of the first race (30) can be adjusted. Tension can be increased or decreased. Dial (62a) can be pulled to quickly release lace tightening system (60a) and loosen lace (30).

A second power shroud (24b), on the other hand, extends from the outer side (41), covers the tongue member (22), and extends to the inner side (38). The second power shroud (24b) includes i) a second upper race guide (46). A first lower race guide (48) is also shown secured to the medial side (38) of the upper (12). A second power shroud (24b) is pulled over the instep region (18) and tightened via a lace tightening system (60b) attached to the heel region.

A second race (33) extends from a second lace tightening system (60b) in the heel area, threaded through the medial race channel (51) and through the channel through a trumpet or eyelet guide (54). out and form a loop between the upper race guide (46) and the lower race guide (48). The second race (33) first enters and exits the second upper race guide (46) at the entry point. After exiting the second upper race guide (46), the race (33) passes downward and enters the first lower race guide (48) at the entry point. The race (33) travels through the first lower race guide (48) and then exits this race guide (48). After exiting the first lower race guide (48), the race (33) extends upward until its path terminates at an end plate (56) attached to the second power shroud (24b). The lace guides have low friction so the laces can be pulled smoothly and firmly from the guides. In this embodiment of the shoe, the second upper lace guide (46) and the first lower lace guide (48) can have the same dimensions as the lace guides discussed above.

In this embodiment, a second lace tightening assembly (60b) is located in the heel region of upper (12). As shown in FIGS. 11-12 and discussed above, the race tightening assembly (60b) may include a dial (62b) covering a spool (not shown) disposed within the housing. In one embodiment, dial (62b) is pushed inward first to engage lace tightening system (60b). The dial (62b) is then rotated clockwise to tighten the lace (33). Tightening the second race (33) pulls the second power shroud (24b) downward as represented by arrow "C". The second power shroud (24b) is pulled downward in the direction of arrow C, which is an angled force acting on the second power shroud (24b). To loosen the second race (33) dial (62b) is rotated in a counterclockwise direction. In this way the tension of the race (33) can be adjusted. The tension can be increased or decreased in steps. The dial (62b) can be pulled up to quickly release the lace tightening system (60a) and loosen the second lace (33).

See FIGS. 13-16. In a fifth embodiment of the upper construction there is a single lace tightening assembly (81) and two power closure straps (82a, 82b). In this embodiment, the upper (12) generally includes an instep region (18) with an opening (20) having a heel collar (79) for foot insertion. The upper (12) may include a complete bootie structure (83) around the collar (79) of the foot-receiving opening (20). The bootie construction (83) enhances comfort and provides resistance to cold and wet environments. Other boot constructions (83) are made of breathable material to provide comfort in hot and humid environments, such as southern regions, and these boots can also be used in the shoe of this invention. . Booties (83) can be constructed from a wide variety of fabric and/or foam materials including Lycra™, Neoprene™, knits, spandex, and spandex blends such as cotton/spandex, nylon/spandex. , and polyester/spandex blends. Laminates such as mesh laminated to foam and liners, such as mesh foam core materials, and Tiong Liong Industrial Co.; , Ltd. Synthetic rubber and foam materials such as Ariaprene(TM) available from Ariaprene Inc. can be used. Although the bootie structure (83) is shown primarily in use with the upper shown in FIGS. 13-16, this is exemplary only and should not be considered limiting. It should be appreciated that bootie (83) can be used with any shoe construction of the present invention. Bootie (83) is particularly effective when upper (12) is made of a foldable material such as knit.

A first power closure strap (82a) extends from the medial side of the upper (12), covers the tongue member (22), and extends to the lateral side. As shown in FIG. 13, the first power closure strap (82a) also includes i) a first upper race guide (84a). On the other hand, a second power closure strap (82b) also extends from the medial side of the upper (12), covers the tongue (22) and extends to the lateral side. The second power closure strap (82b) also includes i) a second upper lace guide (84b). Additionally, a first lower race guide (85a) and a second lower race guide (85b) are fixed to the outer edge or side (41) of the upper (12). As shown in Figures 13-16, the lace (30) extends only one side of the shoe upper (12), yet still provides an optimal closure system and provides a comfortable fit. There is only one strand of lace. That is, it is shown in Figures 13-16 that a single lace (30) is threaded along only the lateral side of the upper (12) of the shoe. In another example, the lace can be threaded so that it extends only along the medial side of the upper (12).

Further, as shown in FIG. 13, the lace (30) extends from the lace tightening assembly (81) in the heel area and is threaded through the outer channel (52) and, upon exiting this channel, the two power closures. A loop is formed between the straps (82a, 82b) and the first and second lower race guides (85a, 85b). More specifically, the race (30) travels through a first lower race guide (85a) and then exits the guide (85a) at an exit point. After exiting the first lower race guide (85a), the race (30) extends upward until it enters the first upper race guide (84a) at the entry point. After exiting the first upper race guide (84a) at the exit point, the race (30) passes downward into the second lower race guide (85b). The race (30) travels through a second lower race guide (85b) and then exits the race guide (85b) at an exit point. After exiting the second lower race guide (85b), the race (30) extends upward into the second upper race guide (84b). The race (30) travels through a second upper race guide (84b) and then exits this guide (84b) and extends downward. The race (30) passes downward until its path terminates at an end plate (56) clamped to the outer edge of the upper (12).

In this embodiment, a single lace tightening assembly (81) is located in the heel area of the upper (12). As shown in FIG. 13 and discussed above, the race tightening assembly (81) may include a dial (88) covering a spool (not shown) located within the housing. In one embodiment, the dial (88) is pushed inwards first to engage the lace tightening system (81). The dial (88) is then rotated clockwise to tighten the lace (30). As the race (30) is tightened, the first and second power closure straps (82a, 82b) are pulled downward as represented by arrow D. The power closure straps (82a, 82b) are pulled downward in the direction of arrow D, which is an angled force acting on the first and second power closure straps (82a, 82b). To loosen the lace (30), rotate the dial (88) counterclockwise. In this way the tension of the race (30) can be adjusted. The tension can be increased or decreased in steps. The dial (88) can be pulled to quickly release the lace tightening system (81) and loosen the lace (30).

The power closure straps (82a, 82b) are preferably made of a lightweight, high strength fabric material. For example, fabrics made of polyamide (nylon), aramid such as Kevlar™, polyurethane, polypropylene, polyester, etc. can be used to make the power closure straps (82a, 82b). Also, spandex or rubber cloth materials such as styrene butadiene rubber (SBR) and neoprene (tm) synthetic rubbers can be used to form the power closure straps (82a, 82b). Natural and synthetic rubber materials can be used. Examples of synthetic rubber materials include polybutadiene, polyisoprene, ethylene-propylene rubber (“EPR”), ethylene-propylene-diene (“EPDM”) rubber, styrene-butadiene rubber, styrene block copolymer rubber (“SI”). , "SIS", "SB", "SBS", "SIBS", "SEBS", "SEPS", etc., where "S" is styrene, "I" is isobutylene, "E" is ethylene, and "P" is is propylene and "B" is butadiene), polyalkenamers, butyl rubbers, nitrile rubbers, and blends of two or more thereof. Natural leather, synthetic leather, knitwear, non-woven fabrics, natural fibers and synthetic fibers can also be used. For example, synthetic fiber fabrics made from nylons, polyesters, polyolefins, polyurethanes, rubbers, and combinations thereof can be used. Microfibers and nonwovens can be used, as well as textured knits and rolled fine fabrics. All of these fiber and fabric structures can be reinforced with various materials. Hot melt thermoplastic polyurethane (TPU) can also be applied to these structures.

In yet another embodiment, power closure straps (82a, 82b) are formed from small straps, stitching, or other suitable fastening such that power closure straps (82a, 82b) function as a single power shroud structure. Means can be combined together. In still other embodiments, a single power closure strap can be used. Such power closure straps can have a single unitary unitary construction.

Referring to Figure 17, in a sixth embodiment, the shoe upper (12) has the same construction as the above-described shoe upper shown in Figures 13-16, except for the following differences. i) There is a half bootie construction (87) around the collar (79) of the foot receiving opening (20) as opposed to the full bootie construction (85) shown in Figures 13-16. ii) Instead of the two power closure straps (82a, 82b) shown in Figures 13-16, there are two power connector webbings (90a, 90b) extending through channels (98a, 98b).

Power connector webbings (90a, 90b) extend through channels (98a, 98b) of tongue member (22). In another example, the power connector webbings (90a, 90b) may extend inside the bootie, i.e., the channels (98a, 98b) may connect with the tongue member (22) and liner of the bootie (87). can extend between The power connect webbing (90a, 90b) can be considered "floating". In yet another example, webbing (90a, 90b) can extend over bootie (87). The power connector webbings (90a, 90b) can be placed inside or on the instep region so that they extend between the medial and lateral sides of the upper (12). The webbings (90a, 90b) may be made from any suitable fibrous material such as, for example, polyamide (nylon), aramid such as Kevlar™ fibers, polyester, polypropylene, polyethylene, polyurethane, rubber. Other suitable fiber and fabric materials that can be used to make the webbing are described above.

The first power webbing (90a) also includes i) a first upper race guide (84a). The second power webbing (90b) also includes i) a second upper race guide (84b). Additionally, a first lower race guide (85a) and a second lower race guide (85b) are fixed to the outer edge (42) of the upper (12). The lace (30) extends from the lace tightening assembly (81) in the heel area and exits through a trumpet or eyelet guide (54) in the lace channel (52) and into the lace guide. The race forms a loop between the two power connector webbings (90a, 90b) and the first and second lower race guides (85a, 85b). A race tightening assembly (81) may be used to tighten or loosen the race (30) as described above.

Referring to Figures 18-21, in a seventh embodiment, the shoe upper (12) also includes two power connector webbings (90a, 90b). The power connect webbings (90a, 90b) can be placed inside or on the instep region so they extend between the medial side and lateral sites of the upper (12). The webbings (90a, 90b) may be made from any suitable fibrous material such as, for example, polyamide (nylon), aramid such as Kevlar™ fibers, polyester, polypropylene, polyethylene, polyurethane, rubber. The first power webbing (90a) also includes i) a first upper race guide (93a). A second power webbing (90b) also extends from the medial side of upper (12), covers tongue (22), and extends to the lateral side of upper (12). The second power webbing (90b) also includes i) a second upper race guide (93b).

The race (30a) extends from the heel region lace tightening assembly (89) and is threaded through the outer race channel (52a) and through the eyelet (54) to the first lower race as it exits that channel. Enter the guide (91a) and then exit the guide (91a). After exiting the first lower outer guide (91a), the race (30a) extends downward until it enters the first upper outer race guide (93a) at the exit point. After the race (30a) exits the first upper outer race guide (93a), the race (30a) extends downward and enters the second lower outer race guide (91b) at the entry point. The race (30a) travels through a second lower race guide (91b) and then exits the guide (91b). After exiting the second lower race guide (91b), the race (30a) extends upward into a second upper outer race guide (93b). The race (30a) travels through a second upper outer race guide (93b) and then exits this guide (93b) at an exit point and extends downward. The path of the lace (30a) may then terminate in a termination plate (56a) secured to the lateral edge (41) of the forefoot region (21). In this version there are two races (30a, 30b). The lace (30a) extends along the lateral side (41) of the shoe upper and the lace (30b) extends along the medial side (38) of the shoe upper (12). The shoelaces (30a, 30b) are not connected. However, the system closes tightly around the foot to provide a comfortable, smooth fit. In this version there are two races (30a, 30b). Both races (30a, 30b) extend from the same race tightening assembly (89). In other examples, the races can extend along the outer side and the races extending along the inner side can connect, as described below. That is, there is a single race that runs along the outside and inside, forming a continuous loop. For example, the laces can be connected via a forefoot connector screw guide (97) as shown in FIGS. 22-25 and discussed below.

The path of the lace strands (30a) along the outer side (41) of the shoe has been previously described. In the path of the second lace strand (30b) along the medial side (38), the lace extends from the lace tightening assembly (89) in the heel area and passes through the medial lace channel (52b), which Upon exiting the channel through eyelet (54), it enters and then exits first lower inner race guide (91d). After exiting the first lower inner race guide (91d), the race (30b) enters the first upper inner race guide (93d) at the entry point, extends upwards and then exits the guide (93d). After exiting the first upper inner race guide (93d), the race (30a) passes downward and enters the second lower inner race guide (91c) at the entry point. Race (30b) travels through a second lower race guide (91c) and then exits guide (91c). After exiting the second lower race guide (91c), the race (30b) extends upward into the second upper inner race guide (93c). Race (30b) travels through a second upper inner race guide (93c) and then exits guide (93b) at an exit point and extends downward. The path of the lace (30b) may then terminate in a termination plate (56b) secured to the medial edge (38) of the forefoot region (21). Thus, one lace strand (30a) extends along the outer side (41) and the other lace strand (30b) extends along the inner side (38). Each path of lace strands (30a, 30b) terminates in end plates (56a, 56b) on the lateral and medial sides (41, 38) of the shoe upper.

In another version, the race (30) passes downward through a second upper outer race guide (93b) and then a channel (not shown) running between the upper (12) and the midsole (14). ). A lace (30) passes through this channel and runs along the medial side (38) of the upper of the shoe. Thus, the same race (30) is threaded through upper inner race guides (93c, 93d) and lower inner race guides (91c, 91d). The race (30) passes through a second lower inner race guide (91d) and then through an inner race channel (52b) and back to the race tightening assembly (89). Thus, in this example, the lace (30) forms a continuous loop so that it extends along both the lateral and medial sides and around the heel area of the shoe upper (12).

Referring to Figures 22-25, in an eighth embodiment, the shoe upper (12) has the same shoe construction as the shoe upper shown in Figures 18-21, with the following additional elements: i) a third lower outer race guide (95) located on the outer side of the upper; ii) a third lower inner race guide (96) located on the inner side of the upper; and iii. ) Forefoot Connector Thread Guide (97) attached to the forefoot region of the upper. In this embodiment, the lace (30) is a continuous loop such that the lace extends along both the lateral and medial sides of the shoe upper (12) and around the heel region of the shoe upper (12). to form

The race (30) extends from the heel area lace tightening assembly (89) and is threaded through the outer race channel (52) and upon exiting this channel enters the first lower race guide (91a) and then into the outer race channel (52). Finally, exit this guide (91a) at the exit point. After exiting the first lower outer race guide (91a), the race (30) extends upward until it enters and exits the first upper outer race guide (93a) at the entry point. After exiting the first upper outer race guide (93a) at the exit point, the race (30) passes downward and enters the second lower outer race guide (91b) at the entry point. The race (30) travels through a second lower race guide (91b) and then exits this guide (91b) at an exit point. After exiting the second lower race guide (91b), the race (30) extends upward into the second upper outer race guide (93b). The race (30) travels through a second upper outer race guide (93b) and then exits this guide (93b) at an exit point and extends downward. The race (30) is then threaded through a third lower race guide (95) on the outboard side. After exiting the third lower race guide (95), the race (30) extends upward and is threaded through the forefoot connector thread guide (97) and onto the medial side of the upper (12).

As shown in Figures 23-24, the same race (30) then enters the first lower inner race guide (115a) and then exits this guide (115) at an exit point. After exiting the first lower inner race guide (115a), the race (30) extends upwards until it enters the first upper inner race guide (117a) at its entry point and passes through this guide (117a). Get out. After exiting the first upper inner race guide (117a) at the exit point, the race (30) passes downward and enters the second lower inner race guide (115b) at the entry point. The race (30) travels through a second lower race guide (115b) and then exits the guide (115b) at an exit point. After exiting the second lower inner race guide (115b), the race (30) extends upward into the second upper inner race guide (117b). The race (30) travels through a second upper inner race guide (117b) and then exits the guide (117b) at an exit point and extends downward. The race (30) passes through a third lower inner race guide (96) and then through an inner race channel (52b) and back to the race tightening assembly (89). Thus, in this example, the lace (30) forms a continuous loop such that the lace extends along both the lateral side (41) and the medial side (38) of the shoe upper (12) and the It extends around the heel area of the upper (12).

In a ninth embodiment, as shown in Figures 26-29, there is a first (outer) upper connector thread guide (94) located on the outer side of the shoe upper. In Figures 26-29, the first (outer) upper connector screw guide (94) is coupled to the second (inner) upper connector thread guide (107) as further described below. The lace (30) extends from the lace tightening assembly (99) in the heel area and exits the trumpet or eyelet guide (54). The race (30) then enters the lower outer race guide (104) at the entry point and exits this guide (104). After exiting the lower outer race guide (104), the race (30) passes above and enters the first (outer) upper connector thread guide (94) at the entry point. The race then travels through the upper connector thread guide (94) and extends downward. The path of the lace (30) may then terminate in a termination plate (56) secured to the lateral edge (41) of the forefoot region (21).

In this version there are two lace strands (30a, 30b). The lace (30a) extends along the outer side (41) of the shoe upper as described above. The lace (30b), on the other hand, extends along the medial side (38) of the shoe upper (12). The races (30a, 30b) are not connected. The path of the lace strands (30a) along the outer side (41) of the shoe has been previously described. In the path of the lace strand (30b) along the medial side (38), the lace extends from the lace tightening assembly (99) in the heel area and is threaded through the medial lace channel (52b). As the race (30b) exits the channel through the eyelet (54) it enters the lower inner race guide (113) and then exits this guide (113). After exiting the lower inner race guide (113) at the exit point, the race (30b) passes upwards and enters the second (inner) upper connector thread guide (107) at the entry point. The race (30b) then travels through the upper connector thread guide (107) and then extends downward. The path of the lace (30b) may then terminate in a termination plate (56) secured to the medial edge (41) of the forefoot region (21). Although in this version there are two separate lace strands (30a, 30b), the system closes tightly around the foot and provides a comfortable and smooth fit. Both lace strands (30a, 30b) extend from the same lace tightening assembly (99).

In another version, the race (30) passes downward from the first (outer) upper connector thread guide (94) and then through a channel (not shown) running between the upper and midsole. can do. The lace (30) passes through the channel and travels up along the medial side (38) of the shoe upper (12). Thus, in this example, there is a single lace (30) forming a continuous loop, so that the lace (30) extends along both the lateral and medial sides of the shoe upper, and along the shoe upper. Extends around the heel area. In this version, the same lace (30) extends along both the lateral and medial sides of the upper (12) of the shoe. That is, the race (30) is threaded through a channel (not shown) and passes upwardly into the second (inner) upper connector thread guide (107) at the entry point. The lace then travels through the second (inner) connector thread guide (107) and then out until it passes the lower inner lace guide (113) on the inner edge of the shoe upper (12). extends downward. The race (30) is then threaded through the inner race channel (52b) and back to the race tightening assembly (99). Thus, in this example, the same lace (30) forms a continuous loop so that it extends along both the lateral and medial sides of the upper (12) of the shoe.

The first (outer) and second (inner) upper connector thread guides (94, 107) can be coupled together by a wide variety of fastening means, including but not limited to: Including molded plastic, metal wire (100, 101), carbon fiber, carbon fiber composites, fabrics, webbing, fibers and other lacing systems. In another example, when bootie (83) is used in instep region (18), connector thread guides (94, 107) can go inside the bootie member.

In this embodiment, the lace tightening assembly (99) is located in the heel area of the upper (12). As shown in FIGS. 27 and 28 and previously described, the race tightening assembly (99) may include a dial (88) covering a spool (not shown) located within the housing. In one embodiment, the dial (88) is pushed inwards first to engage the lace tightening system (99). The dial (88) is then rotated clockwise to tighten the lace (30). Tightening the race (30) pulls the first upper (outer) connector thread guide (99) downward as represented by arrow E. The second upper (inner) connector screw guide (107) is retracted downward as represented by arrow F. To loosen the lace (30), rotate the dial (88) counterclockwise. In this way the tension of the race (30) can be adjusted. The tension can be increased or decreased in steps. The dial (88) can be pulled up to quickly release the lace tightening system (99) and loosen the lace (30).

In the tenth embodiment, as shown in Figures 30-33, the power shroud (110) has two sections. an upper section (111) and a lower section (112). The power shroud (100) is a one-piece unitary structure with an upper section (111) and a lower section (112). The upper and lower parts (111, 112) can be made of any suitable material, including Neoprene™ synthetic rubber, to provide high comfort and a smooth fit. Other comfortable, elastic materials such as knits, spandex, and spandex blends such as cotton/spandex, nylon/spandex, and polyester/spandex blends can be used. Natural leather, synthetic leather, knitwear, non-woven fabrics, natural fibers and synthetic fibers can also be used. For example, synthetic fiber fabrics made from nylons, polyesters, polyolefins, polyurethanes, rubbers, and combinations thereof can be used. Microfibers and nonwovens can be used, as well as textured knits and rolled fine fabrics. All of these fiber and fabric structures can be reinforced with a variety of materials. Hot melt thermoplastic polyurethane (TPU) can also be applied to these structures.

As shown in FIG. 30, the first and second upper race guides (114, 122) may be coupled to the upper section (111) of the power shroud (100) by stitching or other means. Alternatively, guides (114, 122) may be an integral part of shroud (100). The lace (30) extends from the lace tightening assembly (119) in the heel area and exits the trumpet or eyelet guide (54). The race then enters the first lower race guide (116) at an entry point and exits this race guide (116) at an exit point. A first lower race guide (116) is oriented in an angled position. After exiting the first lower race guide (116) at the exit point, the race (30) passes upward and enters the first upper race guide (114) at the entry point. The race (30) is threaded through a first upper race guide (114) and then exits a race guide (118). After exiting the first upper race guide (114), the race extends downward to a second lower race guide (120) where it enters guide (120) at an entry point. The race (30) then travels through the second lower race guide (120) and exits this race guide (120). The race (30) then passes upward as it enters the second upper race guide (122). The race (30) travels through a second upper race guide (122) and then exits this guide (122). The race (30) then extends downward until its path terminates at an end plate (56) fixed to the outer edge (41) of the upper (12). In the embodiment shown in Figures 130-33, a loop is formed between the upper and lower race guides. However, there are no intersecting zones within the loop. As shown in Figures 30-33, the lace (30) extends only on one side of the shoe, yet still provides an optimal closure system and provides a comfortable fit. The lace (30) may then terminate in an end plate (56) secured to the lateral edge (41) of the forefoot region (21).

In other versions there are two lace strands. As mentioned above, one lace extends along the outer side (41) of the upper (12) of the shoe. Another lace strand extends along the medial side (38) of the shoe upper (12). Races are not combined. Rather, the lace strands terminate in end plates on each of the lateral and medial sides of the shoe.

34-41, in this upper construction embodiment there is a single lace tightening assembly (125) and three power closure straps (128, 129, 130). In this embodiment, the upper (12) generally includes an instep region (18) with an opening (20) having a heel collar (79) for foot insertion. As shown in Figures 34-37, in one example the heel collar (79) is low profile. In another example, as shown in Figures 38-41, the heel collar (79) has a high profile. The path of the laces (30) along the medial side of the shoe may also vary as shown in Figures 36 and 40.

Referring back to FIG. 34, the race (30) extends from the heel region lace tightening assembly (119) and is threaded through the outer race channel (52) and upon exiting this channel, the first upper race. Entering the guide (132), which is attached to the first (upper) power closure strap (128), exits the guide (132) at an exit point. After exiting the first upper outer race guide (132), the race (30) extends downward until it enters the lower outer race guide (134) and then exits the lower outer race guide (134) at the exit point. Get out. The lower outer race guide (134) is attached to the second (middle) power closure strap (129). After the race (30) exits the lower race guide (134), it is threaded upwards into a second upper side race guide (136) which in turn leads to a third (136) Bottom) Attached to the power closure strap (130). The race (30) travels through a second upper race guide (136) and then exits this guide (136). The race (30) then passes downward until its path terminates at an end plate (56) fixed to the outer edge (41) of the upper (12).

In this version there are two lace strands (30a, 30b). The lace (30a) extends along the lateral side (41) of the shoe upper and the lace (30b) extends along the medial side (38) of the shoe upper (12). The races (30a, 30b) are not connected. However, the system closes tightly around the foot to provide a comfortable, smooth fit. The route of the lace strands (30a) along the outer site (41) of the shoe has been described above. In the path of the lace strand (30b) along the medial side (38), the lace extends from the lace tightening assembly (119) in the heel area and is threaded through the medial lace channel (52b), which passes through the eyelet (54). ), it enters the lower inner race guide (113) (Fig. 36). In another example (shown in FIG. 40), the race (30b) can enter the upper inner race guide (124) before entering the lower inner race guide (113). The race (30b) then exits the race guide (113) and then enters the upper inner race guide (190) attached to the second (middle) power closure strap (129). The race (30b) then passes downward until its path terminates at an end plate (56) fixed to the inner edge (38) of the upper (12).

In another version, the lace (30) passes downwards and then it can pass through a channel (not shown) running between the upper sole and the midsole. The lace (30) passes through this channel and travels up along the medial side (38) of the shoe upper (12). Thus, in this example, the lace (30) forms a continuous loop so that it extends along both the lateral and medial sides of the shoe upper and around the heel region of the shoe upper. In this version the same laces (30) run along the inner side of the upper of the shoe. That is, the race (30) passes upwards and enters the inner upper connector thread guide (109) at the entry point. The race then travels through the inner connector thread guide (109) and then extends downward until it passes the second lower race guide (113) on the inner side (38). The race (30) is then threaded through the inner race channel (52b) and back to the race tightening assembly (119). Thus, in this example, the lace (30) forms a continuous loop so that it extends along both the lateral and medial sides and the heel area of the upper (12) of the shoe.

As shown in FIGS. 34-41 and discussed above, the race tightening assembly (119) may include a dial (121) covering a spool (not shown) located within the housing. As the race (30) is tightened via the race tightening assembly (119), the upper power closure strap (128) is pulled downward as represented by arrow H. The central power closure strap (129) is pulled downward as represented by arrow I. The lower power closure strap (130) is pulled downward as represented by arrow J. The race guides have low friction so that the race (30) can be pulled smoothly and firmly from the guides. Rotate the dial (121) counter-clockwise to loosen the lace (30). In this way the tension of the race (30) can be adjusted. The tension can be increased or decreased in steps. The dial (121) can be pulled up to quickly release the lace tightening system (110) and loosen the lace (30). The lace (30) thus forms a continuous loop such that the lace extends along the lateral and medial sides of the shoe upper (12) and around the heel region of the shoe upper (12). do. Adjusting the lace (30) provides a substantially uniform application of force to the upper of the shoe. The shoe is evenly tightened against the wearer's foot. This helps prevent pressure points on the wearer's foot.

In yet another embodiment, as shown in Figures 42-45, the shoe upper (12) has the same shoe construction as the shoe upper shown in Figures 26-29, with the following modifications: . i) The first (outer) upper connector thread guide (94) located on the outer side of the upper of the shoe is made of webbing rather than plastic material. ii) There is an upper race guide (135) adjacent to the outer race channel (52a). iii) There are two lower race guides (104, 137). iv) There is a forefoot connector thread guide (140) attached to the forefoot region of the upper.

The golf shoe of the present invention provides a secure yet comfortable fit. In one embodiment, the tension in the race is substantially the same as it passes through different race guides. In other embodiments, the tension can vary. Adjusting the laces applies a substantially uniform force to the upper of the shoe. The system of the present invention evenly distributes lateral (lateral), medial (medial), and downward clamping forces along the length of the foot. The lace guide is pulled evenly across the instep area, closing the instep area and pulling the foot down. Thus, the shoe is evenly tightened against the wearer's foot. This helps prevent pressure points on the wearer's feet. The foot is drawn into the heel area along the lateral and medial side regions to provide a secure yet comfortable fit.

Additionally, the lace tightening system of the present invention can be incrementally adjusted to tighten or loosen the lace as desired by the wearer. The golf shoe of this invention provides a high level of comfort and stability and is custom fit. The lace tightening system is micro-adjustable to provide the perfect fit for golfers and shoe fitting preferences. Various embodiments of golf shoes have both high levels of stability, power, and traction, as well as high levels of flexibility. The shoe provides stability, power, and traction so there is no slippage and the golfer can maintain balance when swinging the club. At the same time, the shoes are highly flexible, allowing the golfer to comfortably walk around the course and perform other golfing activities.

The shoe of the present invention also helps provide the golfer with strength and stability when shifting his weight during the golf swing. For example, when a golfer initially places his feet (ie, when addressing the ball) before initiating the swing motion of the club, his weight is evenly distributed between his front foot and his back foot. When a golfer initiates the backswing, the weight is primarily transferred to the back foot. At the beginning of the downswing, there is a lot of pressure on the back foot. Therefore, the rear foot is sometimes referred to as the driving foot and the front foot as the stabilizing foot. As the golfer continues the swing to drive the ball, the weight is transferred from the driving foot to the front (stabilizing) foot. During the swing motion, there is some degree of rotation of the front and rear feet, and this rotation must be controlled. It is important that both the front and back feet do not move or slip substantially when making the shot. The golf shoe of this invention helps prevent this movement and slippage. The golf shoe of the present invention helps provide stability and support by evenly distributing lateral, medial, and downward clamping forces along the length of the foot.
