Description

TECHNICAL FIELD This invention relates generally to shoes, and more particularly to golf shoes with improved outsoles. The outsole includes various regions or zones of traction members that provide traction for on- and off-course activities. The traction members are arranged on the outsole in a pattern without grooves. Traction members and unique patterns on the outsole provide a shoe with high traction and low turf trench characteristics. The outsole further minimizes damage to the putting green with a certain amount of traction.

Professional and amateur golfers today use specially designed golf shoes. Typically, golf shoes include an upper portion and an outsole portion, along with a midsole that joins the upper to the outsole. The upper has a conventional shape for inserting the user's foot, thus covering and protecting the foot within 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 contact and penetrate the ground and engage the ground surface. These elements help provide the golfer with better foot traction as he walks and plays the course.

The terms "spikes" and "cleats" are often used interchangeably in the golf industry. Some golfers prefer the term "spike". This is because cleats are commonly associated with other sports such as baseball, soccer, and soccer. Other golfers prefer to use the term "cleats." This is because spikes are commonly associated with non-grass sports such as track and bicycle. In the following description, the term "spike" is used for convenience. Golf shoe spikes can be made of metal or plastic materials. One problem with metal spikes, however, is that they are usually elongated pieces that extend downward with sharp points that can pierce the surface of the putting green, leaving holes and causing other damage. is. These metal spikes can also damage other surfaces on the golf course, such as clubhouse carpets and floors. Today, most golf courses require golfers to use non-metallic spikes. Plastic spikes usually have a round base with a central stud on one side. On the other side of the round base are radial arms with traction lugs for contacting the ground. Threads are spaced around the stud of the spike for insertion into a threaded receptacle on the outsole of the shoe, as further described below. These plastic spikes tend to cause less damage to greens and clubhouse floors because they can be easily secured and later removed from locking receptacles on the outsole.

If spikes are present on the golf shoe, they are preferably removably secured to receptacles (sockets) in the outsole. A receptacle may be located in a molded pod attached to the outsole. Molded pods provide additional stability and balance to the shoe. The spike can be easily inserted and removed from the receptacle. A slight clockwise twist after insertion of the spike typically secures the spike to the receptacle. A slight counter-clockwise twist of the spike allows it to be removed from the receptacle.

In recent years, "spikeless" or "cleatless" shoes have become more popular. The outsoles of these shoes contain rubber or plastic traction members, but do not contain spikes or cleats. These traction members protrude from the bottom surface of the outsole to contact the ground. Shoes are designed for on- and off-course use. In short, the shoe provides golfers with excellent stability and traction on the course, whether it's on the tees, fairways or greens. Additionally, the shoes are lightweight, comfortable, and can be used off the golf course. These shoes are comfortable to wear in the clubhouse, office, or other off-course locations.

As golfers shift their weight by swinging the club, their feet absorb tremendous forces. For example, when a right-handed golfer first places his feet before initiating the swing motion of the club (ie, when addressing the ball), his weight is evenly distributed between his front and rear feet. When a golfer initiates the backswing, the weight shifts primarily to the back foot. At the beginning of the downswing, there is a lot of pressure on the back foot. Therefore, the hind foot is called the driving foot and the front foot is called the stabilizing foot. As the golfer hits the ball following a swing, the weight is transferred from the driving foot to the front (stabilizing) foot. Although there are several pivots in the front and rear feet during the swing motion, this pivot motion needs to be controlled. It is important that the foot does not move or slip when making the shot. Good foot traction is important during the golf shot cycle. Accordingly, conventional golf shoes have traction members and spikes located at various locations throughout the outsole.

For example, U.S. Pat. No. 8,677,657 (Bacon et al.) describes a rigid thermoplastic polyurethane in which the front portion is molded into a relatively soft, flexible thermoplastic polyurethane and the heel portion is molded into a relatively rigid TPU. A golf shoe outsole with a pod is disclosed. Each pod includes a cleat receptacle for inserting and removing cleats. U.S. Pat. No. 7,895,773 (Robinson, Jr. et al.) discloses a golf shoe having a collapsible supportable gel pad housed in recesses in the outsole adjacent to the metatarsals. The shoe includes replaceable, relatively soft plastic spikes and non-replaceable, relatively hard rubber cleats. After a period of time (such as three months) and the replacement spikes wear out, the golfer can replace them to restore traction. If the golfer so desires, the height of the replacement spike can be selected to match the height of non-replaceable cleats that may have worn.

In other examples, the outsole may include traction members, spikes, and/or cleats arranged in a linear pattern with lateral and longitudinal rows extending across the outsole. For example, US Pat. No. 4,782,604 (Wen-Shown) discloses a golf shoe outsole with a plurality of removable metal spikes and a plurality of soft cleats arranged in a linear pattern. there is Metal cleats are placed on the ball and heel portions of the outsole. Soft cleats are placed around the sole for the purposes of positioning, bearing loads, and providing resilience.

US Pat. No. 9,332,803 (Kasprzak) discloses a golf shoe outsole with cleats distributed along the forefoot and heel regions. The cleats are arranged in rows along the longitudinal length of the outsole. Cleats are basically cruciform. The forefoot region includes the ball of the thumb region and the toe region. The thumb ball and heel areas have higher and wider cleats than other areas of the sole. The cleat height along the thumb ball area and heel area is approximately the same.

In another version, the traction members are arranged in a circular pattern, with each traction element positioned in a ring having substantially the same radius and center as the other traction elements within the ring. For example, US Pat. No. 8,011,118 (Gerber) discloses a shoe having an outsole with a circular tread pattern. The circular tread pattern includes a first circular tread having a first radius, the first circular tread extending less than 360 degrees circumferentially about the center of the circular tread pattern. The circular tread pattern also includes a second circular tread having a second radius greater than the first circular tread. And the second circular tread also extends less than 360 degrees circumferentially about the center of the circular tread. According to the '118 patent, the circular tread pattern provides sufficient traction in all directions, but also allows the wearer to pivot around the pivot portion.

However, one drawback of some conventional golf shoes is that they can damage the turf of a golf course. For example, traction members, spikes, and cleats can drag along surfaces and damage grass blades and roots. This damage is called trench effect. This crack in grass and roots creates an uneven surface on putting greens and other courses. There are relatively high and low surfaces, which lead to turf discoloration and browning. The digging into the ground and the grooves in the turf from the outsole of the shoe create problems for golfers at all stages of the game. For example, grass trenches can affect a golfer hitting the ball off the tee, hitting the fairway, putting on the green, and even walking the course. Even the most careful golfers can damage the green when walking or putting. This is especially a problem when the putting green is wet. Grooving the grass and dirt can slow the overall flexibility and pivoting motion of the shoe. Also, turf digging and clogging on the outsole can cause golfers to feel awkward and uncomfortable when walking the course or swinging the club to make a shot. When the traction members and cleats are arranged linearly across the outsole, this turf trench effect occurs in both the 90 degree and 0 degree directions, as explained in more detail below. On the other hand, if the cleats are arranged in an overlapping circular pattern (double radial configuration), there will tend to be few turf trenches in the 90 degree direction, but more turf trenches in the 0 degree direction. . In yet another example, when the cleats are arranged in a concentric pattern, trenches can occur in various directions, including rotational directions, as described in more detail below.

Accordingly, there is a need for golf shoes with improved outsoles that can provide high levels of stability and traction. Shoes must hold and support the medial and lateral sides of the golfer's foot. This is because golfers shift their weight when making golf shots. The shoe must be non-slip and provide good traction so that the golfer can maintain his balance. At the same time, the outsole of the shoe should have minimal turf trench properties. Golfers who wear shoes must be able to walk and play the course comfortably with minimal damage to the turf of the course. The present invention provides a new golf shoe construction that provides golfers with improved traction as well as other beneficial properties, features and advantages, including minimal turf trenching properties.

U.S. Pat. No. 8,677,657 U.S. Pat. No. 7,895,773 U.S. Pat. No. 4,782,604 U.S. Pat. No. 9,332,803 U.S. Pat. No. 8,011,118

The present invention provides a golf shoe with an outsole having tiles of various zones. Each zone includes various traction members for gripping both golf course and off-course surfaces. The traction members are arranged on the outsole in a pattern without grooves. The traction members and the unique pattern of traction members on the outsole help provide the shoe with high traction and minimal turf trenching properties. This outsole further minimizes damage to other surfaces such as putting greens and clubhouse floors. This shoe reduces golf course damage for a given amount of traction.

The shoe includes an upper portion and a sole portion with a midsole joining the upper to the outsole. Looking at the bottom surface of the outsole, the outsole includes sets of spiral paths that intersect each other. For example, one set of helical paths is called set A; the other set of helical paths is called set B. Each helical path in set A has a common origin and includes multiple helical segments radiating from that point. The curvature of each helical segment in set A is different. Similar to the helical paths of set A, each helical path of set B has a common origin and includes a plurality of helical segments radiating from that point. The curvature of each helical segment in set B is also different. The first set of helical paths (A) is logarithmic or normal and the second set of helical paths (B) is the inverse of the first set (A). These sets of helical paths (A) and (B) can thus be superimposed on each other. When the spiral paths of sets (A) and (B) are superimposed on each other, the curved sub-segments of the spiral segments of set A and the curved sub-segments of the spiral segments of set B are joined together to form a quadrilateral tile. Pieces are formed. The intersections of these sets of spiral paths (A) and (B) form the four corners of these tile pieces. In the outsole of this invention, these tile pieces include protruding traction members .

For example, looking at the outsole of the right shoe, the forefoot region of the outsole is tiled with a first (lateral) zone extending along the perimeter of one of the forefoot regions, including protruding traction members. include. These traction members in the lateral zone are primarily used for golf-specific traction, i.e., they help control the lateral traction of the forefoot and prevent foot slippage during golf shots. help prevent. The third (medial) zone tiles include projecting traction members extending along the opposite perimeter of the forefoot region. These traction members in the inner zone have a large contact area and prevent slipping on hard, wet and smooth surfaces. All traction members maximize ground contact with a predetermined amount of traction member material (rubber, etc.) within that particular zone. A second (intermediate) zone tile containing protruding traction members is positioned between the first and third zones. These traction members in the intermediate zone are relatively softer and more flexible than the traction members in the adjacent outer and inner zones. These traction members provide comfort and tend to distribute pressure from the medial (second) zone to the periphery of the sole, ie, lateral (first) and medial (third) zones. be. The intermediate zone thus acts as a comfort zone that relieves pressure on the center of the sole and pushes it outward and inward of the sole. As further described below, the pattern of traction members in the outer and inner zones provides improved traction on both hard and soft surfaces. In one preferred embodiment, the traction members are made from a rubber material and the traction members in all zones provide maximum grip per volume of rubber material used. The midfoot and rearfoot portions of the outsole include similar zones and traction members, as further described below.

There may be an elliptical pattern (OV1) with a center point superimposed on the spiral path, the center point of the elliptical pattern (OV1) and the origin of the first set of spiral paths (A) being the same fixed point. and the first segment of each helical path has a proximal end and a distal end, and the elliptical pattern intersects the distal end of the first segment. There may be an elliptical pattern (OV2) with a center point superimposed on the spiral path, the center point of the elliptical pattern (OV2) and the origin of the second set of spiral paths (B) being at the same fixed point. and the second segment of each helical path has a proximal end and a distal end, and the elliptical pattern intersects the distal end of the second segment.

Referring to the drawings, like reference numerals are used to designate like elements, and with particular reference to Figure 1, one embodiment of the golf shoe (10) of the present invention is shown. A shoe (10) includes an upper portion (12) and an outsole portion (16) with a midsole (14) joining the upper portion (12) to the outsole portion (16). The surfaces shown are for the right shoe, and the components of the left shoe are mirror images of the right shoe. Note that shoes may be made in a variety of sizes, so the size of the shoe components may be adjusted according to the size of the shoe.

The upper (12) has a traditional shape and is made from standard upper materials such as, for example, natural leather, synthetic leather, non-woven materials, natural fabrics, and synthetic fabrics. For example, breathable, mesh synthetic fiber fabrics made from nylons, polyesters, polyolefins, polyurethanes, rubbers, and combinations thereof can be used. The materials used to construct the upper are selected based on desired properties such as breathability, durability, flexibility and comfort. In one preferred example, upper (12) is made of a mesh material. The upper materials are sewn or glued together to form the upper structure. Referring to FIG. 1A, the upper (12) generally includes an instep region (18) with an opening (20) for inserting the foot. The upper includes a vamp (19) for covering the front part of the foot. The instep region includes a tongue member (22) and a saddle strip (21) covering the quarter section (23) of the upper and attached to foxing (29) in the heel region. The upper (12) may include an optional ghille strip (31) extending from the rear region of the instep region (18). A lace (24) is typically used to tighten the shoe to follow the contours of the foot. However, other tightening systems may be used, including a metal cable (lace) assembly with a dial, a spool, and a locking mechanism to lock the cable in place. Such lace tightening assemblies are available from Boa Technology, Denver, Colorado 80216. The above-described upper (12) shown in Figures 1 and 1A is but one example of an upper design that may be used in the shoe construction of the present invention, and other upper designs may be used without departing from the spirit and scope of the present invention. can be used.

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, the midsole (14) is molded as a separate piece and then attached to the outsole (14) by stitching, adhesives, or other suitable means using standard techniques known in the art. 16) (not shown). For example, the midsole (14) can be heat pressed to adhere to the top surface of the outsole (16).

Overall, the outsole (16) is designed to provide stability and traction to the shoe. The bottom surface (27) of the outsole (16) includes a plurality of traction members (25) that help provide traction between the shoe and the course and grass. The bottom surface of the outsole and the traction member can be made of any suitable material such as rubber or plastic and combinations thereof. Thermoplastic resins such as nylons, polyesters, polyolefins and polyurethanes can be used. Suitable rubber materials that can be used include, but are not limited to, 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. "S" is styrene, "I" is isobutylene, "E" is ethylene, and "P is propylene and "B" is butadiene), polyalkenamers, butyl rubbers, nitrile rubbers, and blends of two or more thereof. The structure and function of the outsole (16) of the present invention are described in further detail below.

In FIG. 2A, a first set of helical paths (A) is shown. Each helical path (30) has a common origin (32) and includes multiple helical segments (eg, A1, A2, and A3) radiating from that origin (32). The curvature of each segment (A1, A2 and A3) is different. Referring to FIG. 2B, a second set of helical paths (B) is shown. Similar to the helical paths of set (A), each helical path (34) of set (B) has a common origin (36) from which multiple helical segments (e.g., B1, B2, and B3). The curvature of each segment (B1, B2 and B3) is different. The first set of helical paths (A) is logarithmic or canonical and the second set of helical paths (B) is the inverse of the first set (A). These sets of helical paths (A) and (B) can thus be superimposed on each other as shown in FIG. 2C.

When the helical paths of sets (A) and (B) are superimposed on each other, the curved sub-segments of the helical segments from set A and the curved sub-segments of the helical segments from set B are spliced together to form a quadrilateral tile piece. to create In FIG. 2C, a four-sided tile with spiral subsegment sides (33, 35, 37, and 39) is shown. The intersections between the superimposed sets of helical paths (A) and (B) form the corners of these tile pieces. In the shoes of the present invention, these tile strips are positioned on the outsole and include protruding traction members, which are described in further detail below.

The geometry of the helical path is shown in more detail in FIG. 3A. In this figure, the first set of logarithmic (standard) helical paths (A) (FIG. 2A) includes an elliptical pattern (OV1) and an elliptical pattern (OV2) intersecting various helical paths. Elliptical patterns (OV1 and OV2) are used herein to further describe the helical paths (A and B), and it should be understood that this is for illustrative purposes only. The elliptical patterns (OV1 and OV2) do not appear as visible marks or markings on the outsole of the shoe. More specifically, the elliptical pattern (OV1) has a center point (40) and, as shown in FIG. 3A, the center point (40) of the elliptical pattern (OV1) and the first The origin (32) of segment (A1) is the same fixed point. The first segment (A1) of each helical path (A) also has a proximal end (42) and a distal end (44). The elliptical pattern (OV1) intersects the distal end (44) of the first segment (A1) of the helical path (A).

As further shown in FIG. 3A, an elliptical pattern (OV2) with the same center point (40) also overlies the spiral path (A). The center point of the elliptical pattern (OV2) and the origin (32) of the second segment (A2) of the spiral path (A) are the same fixed point. The second segment (A2) of each helical path (B) also has a proximal end (46) and a distal end (48). The elliptical pattern (OV2) intersects the distal end (48) of the second segment (A2) of the helical path (A).

A first set of logarithmic (normal) helical paths (A) and a second set of logarithmic (inverted) helical paths (B) are superimposed on each other as shown in FIG. Although shown with patterns (OV1 and OV2), this is for illustration purposes of FIG. Note that the number of spiral paths in these patterns and the number of spiral segments in a given spiral path are not limited. Although in FIGS. 3A and 3B a helical path comprising three helical segments (A1, A2, and A3) is shown for illustrative purposes, there may be an unlimited number of segments, these segments being It can be scaled to any dimension as further described below.

4A-4C, path lengths of some exemplary helical segments, including helical paths, are shown in more detail. In FIG. 4A, an example of a first set of logarithmic (standard) helical paths (A) is shown, the helical paths comprising a plurality of helical segments. The length of helical pathway segments increases with certain growth factors. Specifically, in this example, the helical path (50) comprises a first helical segment (A1); a second helical segment (A2); a third helical segment (A3); a helical segment (A4); a fifth helical segment (A5); and a sixth helical segment (A6). These helical segments are multiplied by a constant growth factor along the entire helical path. For example, if the length of helical segment A1 is 0.4 inches, the length of helical segment A2 is 0.6 inches, the length of helical segment A3 is 1 inch, and the growth factor is 1.6. is. The growth factors of the various segments are the same while the helical pathway continues to grow, as shown in Table 1 of FIG. 4B. That is, the growth factor remains consistent throughout the helical pathway (eg, growth factor can be 1.6). This example of a growth factor can be expressed in geometric equations as shown in Table 2 of FIG. 4C. As shown in FIGS. 4A-4C, there may be multiple helical segments and multiple elliptical patterns intersecting the various segments of the helical path.

Another example of a spiral pathway comprising multiple spiral pathway segments (A1, A2, A3, A4, A5, and A6) with different growth factors is shown in FIGS. 5A-5C. In this example, the length of helical segment A1 is 0.29 inches, the length of helical segment A2 is 0.45 inches, the length of helical segment A3 is 0.75 inches, and the growth. The factor is 1.61. As shown in Table 3 of FIG. 5B, the growth factors of the various segments are identical as the helical pathway grows and extends outward. That is, the growth factor remains consistent throughout the helical pathway (in this example the growth factor is 1.61). This growth factor can be expressed in a geometric equation as shown in Table 4 of FIG. 5C. The spiral path growth is therefore organic and undisturbed and can be described by mathematical equations as shown in the examples of FIGS. 4A-4C and 5A-5C. The spiral path achieves a natural and organic look on the outsole of the shoe.

Note that the origin of the spiral path can be at various locations. Referring to Figures 6A-6D, there is shown the outsole (64) of a right shoe that includes spiral paths that overlap each other as described above. In FIG. 6A, the origin (52) of the helical path (54) is shown at the arch region (56) of the outsole. In Figure 6B, the origin (58) of the spiral path (54) is shown in the central midfoot region of the outsole. In FIG. 6C, the origin of the helical path (54) is outside the outer (pinkie) edge (60) of the midfoot region of the outsole. And in FIG. 6D, the origin (62) is shown in the central midfoot region of the outsole and the length of the helical segment and helical path is reduced (66). The helical segments and helical paths shown in FIG. 6D are of much smaller scale than the helical segments and helical paths shown in FIGS. 6A-6C.

Referring to Figure 7, the outsole of Figure 6A is shown in more detail, in which the focal point (52) of the spiral path (54) is on the medial side (thumb side) of the outsole, in the arch area. . The generation of intersections (68) and quadrilateral tiles (70) between the various arcuate paths (54) is now shown in more detail. The curved sub-segments (72, 73, 74, 75) of the spiral segment are joined together to create a substantially quadrilateral tile piece (70) on the outsole of the shoe. The intersections of the superimposed sets of helical paths (A) and (B) form the corners of these tile segments (eg corners can be found as 76, 77, 78, 79). These individual tile pieces (70) include various traction members (not shown in FIG. 7), as further described below.

As noted above, in one example, the outsole includes a first set of arcs having a center point medial (thumb side) of the forefoot region and extending generally longitudinally along the forefoot region. have a route. The radius of each arcuate path increases from the center point as the arc extends along the forefoot region. A second set of arcuate paths has a center point at the rear end of the forefoot region and extends generally transversely along the forefoot region. The radius of each arcuate path increases from the center point as the arc extends along the forefoot region.

When the first and second arcuate paths are superimposed on each other, quadrilateral tile strips are formed on the surface of the forefoot region. In one embodiment, the first and second arcuate paths can be confined to the forefoot region, have varying radii, and have intersection points. That is, in one embodiment, only the forefoot region can include four-sided tile strips with protruding traction members. Other regions (eg, the midfoot region and the rearfoot region) may not include traction members, or may include traction members of different construction. In other embodiments, as previously discussed, the overall outsole may include arcuate paths, intersections, and resulting quadrilateral tiles. In still other embodiments, selected areas of the outsole other than the forefoot region can include arcuate paths, intersections, and tile strips.

For example, the outsole may have a first set of arcuate paths extending generally longitudinally along the rearfoot region with a center point positioned medial (thumb side) of the rearfoot region. The radius of each arcuate path increases from the center point as the arc extends along the rear foot. A second set of arcuate paths locates a center point at the trailing edge of the rear foot region and extends generally transversely along the rear foot region. The radius of each arcuate path increases from the center point as the arc extends along the rear foot. When the first and second arcuate paths are superimposed on each other, an intersection is formed between the first and second sets of arcuate paths. The intersections form quadrilateral tile strips on the surface of the rear foot region.

Generally, the anatomy of the foot can be divided into three bony regions. The rear foot region generally includes the ankle (talus) and heel (calcaneus) bones. The midfoot region includes the cuboid, cuneiform, and navicular bones that form the longitudinal arch of the foot. The forefoot region includes the metatarsals and toes. Referring back to FIG. 1, the outsole (16) has a top surface (not shown) and a bottom surface (27). The midsole (14) is joined to the top surface of the outsole (16). The upper (12) is joined to the midsole (14).

Referring to Figure 8, the outsole (16) generally comprises: a forefoot region (80) for supporting the forefoot area; a midfoot region (80) for supporting the midfoot including the arch area; region (82); and a rear foot region (84) for supporting the rear foot, including the heel area. Generally, the forefoot region (80) includes the outsole portion corresponding to the joints connecting the toes and metatarsals to the phalanges. The midfoot region (82) generally includes the outsole portion corresponding to the arch region of the foot. The rear foot region (84) generally includes the outsole portion corresponding to the rear portion of the foot including the calcaneus.

The outsole also includes an outer (little finger side) (86) and an inner (thumb side) (88). A lateral (86) and medial (88) extend through each foot region (80, 82, and 84) and correspond to opposite sides of the outsole. The lateral or lateral edge (86) of the outsole is the side corresponding to the lateral region of the wearer's foot. The outer edge (86) is the side of the wearer's foot that is generally furthest from the wearer's other feet (ie, the side near the fifth toe). The medial or medial edge (88) of the outsole is the side corresponding to the medial region of the wearer's foot. The medial edge (88) 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).

More specifically, the lateral and medial sides extend around the perimeter or perimeter (90) of the outsole (16) from the outsole's leading edge (92) to its trailing edge (94). The front end (92) is the portion of the outsole corresponding to the toe area and the rear end (94) is the portion corresponding to the heel area. The peripheral region generally has a width of about 3 to about 6 mm, measured linearly from the outer or inner edge of the outsole toward the central region of the outsole. Perimeter width varies along the contour of the outsole, from the forefoot region to the midfoot region to the rearfoot region (80, 82, 84).

The outsole regions, sides, and areas mentioned above are not intended to distinguish the exact areas of the outsole. Rather, these regions, sides, and areas are intended to represent general areas of the outsole. The upper (12) and midsole (14) also have such regions, sides and areas. Each region, side, and area may include a front section and a rear section.

[Forefoot region]
As shown in Figure 8, the forefoot region (80) of the outsole includes first (lateral) zone tiles (96) that include projecting traction members (98) extending along the perimeter of the forefoot region. a third (inner) zone tile (100) comprising projecting traction members (102) extending along opposite perimeters of the forefoot region; and positioned between the first and third zones, It includes a second (middle) zone of tiles (104) that includes protruding traction members (106).

Referring to Figures 8, 9 and 9A, the traction members (98) of the tiles (96) of the first (outer) zone are triangular shaped top surfaces (109) and non-recessed areas (110). 108), this non-recessed area (110) forms a contact surface with the ground, and the total contact surface is in the range of about 10 to about 35% based on the total surface area of the tile (70) It is in. In one preferred embodiment, the total footprint is in the range of about 17% to about 28%. These traction members (98) are primarily used for golf-specific traction. In short, these traction members control the lateral traction of the forefoot and prevent the foot from slipping during golf shots.

For example, during normal golf play, golfers make shots with various 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 facing the ball, their right and left feet are in a neutral position. As the golfer makes the backswing, the right foot presses down on the medial forefoot and medial area of the heel, and with the right knee still tucked in, the right foot exerts torque with the ground, causing external foot rotation. resist. 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 toward the front foot and rotates internally as the heel lifts. As mentioned above, great pressures are applied to the outside of the foot during various stages of the golf shot cycle. In this invention, the first zone of the outsole is designed to provide lateral support and stability to the foot. That is, the first zone provides support around the outer (little finger side) edge of the outsole. This first zone helps to hold and support the outside (pinkie side) of the foot as the golfer shifts his weight as he makes the shot. The shoe offers excellent traction and lateral movement control. Thus, golfers have improved stability and balance during all phases of the game.

8, 10 and 10A, the traction members (106) of the second (intermediate) zone tiles (104) are three-sided with three ramps (113, 115, 117). Having a pyramidal shape, the sloping surfaces extend from the pyramidal base and apex (118) and the total footprint ranges from about 5 to about 40% based on the total surface area of the tile (70). In one preferred embodiment, the total footprint is in the range of about 12 to about 33%. Because only one edge (118) of the traction member (106) is in contact with the ground, the grip force per volume of the tile (70) is maximized. These traction members (106) provide comfort and tend to distribute pressure from the medial (second) zone to the periphery of the sole, i.e. the lateral (first) and medial (third) zones. These traction members (106) in the intermediate zone are relatively softer and more flexible than those in the adjacent outer and inner zones. The intermediate zone thus acts as a comfort zone that relieves pressure on the center of the outsole and presses it against the outside and inside of the outsole. Also, when sufficient shoe pressure is applied and the mid-zone traction member (106) is somewhat compressed and flattened, it makes relatively good contact with the ground and provides some grip.

Finally, referring to Figures 8, 11 and 11A, the traction members (102) of the tiles (100) of the third (inner) zone are provided with two inclined surfaces (111, 112) and are triangular in shape. With the recessed stop surface (114), this forms a ground contacting surface, the total ground contacting surface area being in the range of about 20 to about 60% based on the total surface area of the tile (70). In one preferred embodiment, the total footprint ranges from about 27 to about 53%. These traction members (102) have a large contact area and prevent slipping on hard, wet and smooth surfaces. Maximum contact by the traction member (102) is maintained in this third zone (100). The traction member (102) also helps push water out of the shoe as the person follows the normal gait cycle, as will be described in more detail below.

Typically, when a person begins to walk naturally, the outer portion of the heel strikes the ground first, with the foot slightly recumbent. When a person shifts weight onto the front foot, the arch of the foot flattens and pushes the foot down. The foot also begins to rotate slightly inward to a pronated position. In some cases, the foot may rotate inward excessively, a type of walking called hyperpronation. In other instances, the foot does not rotate inward sufficiently, which is called underpronation. Normal foot pressure is applied downwards and the foot begins to move into its normal pronation position, which helps absorb shock. After the foot reaches this neutral (intermediate stance) position, the person pushes on the ball of their foot and continues walking. At this point, the foot is rotated slightly outward again. The traction members described above in the tiles of the third (inner) zone are particularly effective in providing maximum contact with the ground to prevent a person from slipping and losing balance when walking.

[Middle foot area]
As also shown in FIG. 8, the midfoot region (82) of the outsole further includes a one-zone tile (116) that includes a protruding traction member (106) extending along the midfoot region to provide a traction member. has the shape of a three-sided pyramid, which has three sloping faces (113, 115, 117) extending from the base and apex (118) of the pyramid (see Figures 10 and 10A), with a total footprint of It ranges from about 5% to about 40% based on the total surface area of the tile (70). Thus, the traction members (106) in the tiles (116) of the zone of the midfoot region are similar to the traction members (106) found in the tiles of the second (mid) zone (104) located in the forefoot region (80). Similar. In one preferred embodiment, the total footprint is in the range of about 12 to about 33%. As noted above, these traction members (106) provide comfort and tend to distribute pressure from the central region of the midfoot region towards the peripheral edges of the outsole.

[Rear foot area]
Turning to the rear foot region (84) and FIG. 8, the traction members (84) found in this region (84) are similar to the traction members (80) found in the front foot region (80). However, the zones of the rear foot region (84) are reversed with respect to the zones of the front foot region (80). Thus, as shown in Figure 8, there are a first (outer) zone tile (120) comprising protruding traction members (102) extending along the perimeter of the rear foot region (84); Third (medial) zone tiles (122) including protruding traction members (98) extending along the opposite perimeter (medial) of (84); and rearfoot first and third zone tiles. There is a second (intermediate) zone of tiles (124) that includes a protruding traction member (106) positioned between (120, 122).

First, the traction members (102) of the tiles (120) of the first (outer) zone of the rear foot are triangular shaped non-slip tiles with sloping sides (111, 112) and forming a ground contacting surface. With the recessed surface (114) (see FIGS. 11 and 11A), the total ground contact surface area is in the range of about 20 to about 60% based on the total surface area of the tile (70). Thus, the traction members (102) in the tiles (120) of the first (outer) zone of the rear foot are found in the tiles (100) of the third (inner) zone that remain in the forefoot region (80). Similar to (102). As previously discussed, these traction members (102) provide a high contact surface area to prevent slipping on hard, wet and smooth surfaces. Additionally, the horizontally facing sidewalls of the traction member help prevent slippage when the golfer is walking down the slopes of the golf course. Maximum contact by the traction member (102) is maintained at the rearfoot first (outer) zone tiles (120) and the forefoot third (inner) zone tiles (100). be.

On the other hand, as also shown in FIG. 8, the traction member (106) of the tile (124) in the second (middle) zone of the rear foot of the tile (124) has three ramps (106) extending from the base of the pyramid. 113, 115, 117) and vertices (118) (see FIGS. 10 and 10A), with a total footprint of about 5 square meters based on the total surface area of the tile (70). to about 40%. Thus, the traction members (106) in the rearfoot second (intermediate) zone tiles (124) provide the traction found in the second (intermediate) zone tiles (104) located in the forefoot region (80). Similar to member (106). As previously discussed, these traction members (106) provide comfort and tend to distribute pressure from the central zone of the rearfoot region to the perimeter of the sole.

Finally, in FIG. 8, the traction member (98) of the tile (122) of the third (medial) zone of the hindfoot has a triangular top surface (108) comprising a recessed area (109) and a non-recessed area (110). ), the non-recessed area forming a ground contact surface (see FIGS. 9 and 9A), the total ground contact area being between about 10% and about 35% based on the total surface area of the tile (70). is in the range of As previously discussed, these traction members (98) are primarily used for golf-specific traction. In short, these traction members control the lateral traction of the forefoot and rearfoot to prevent foot slippage during play.

The above-described traction zones of the outsole of the present invention help provide improved traction on all surfaces. Additionally, these shoes are ideal for use on the golf course, as each amount of traction provided reduces turf trenching. The shoe of the invention helps prevent damage to the turf of the course, especially the putting green. In contrast, many prior art golf shoes include traction members arranged in a linear or dual radial configuration. These conventional grooved outsole constructions provide low traction force per total area of penetration of the traction member. And this can result in more turf damage per amount of traction. Additionally, the outsoles of these conventional shoes may not have good traction on all surfaces. Such grooved outsoles do not provide optimal traction for injuries occurring on the course. As shown in FIG. 12, this turf trench effect of prior art outsoles containing traction members (130) and grooves (132) in a straight configuration (rows along the longitudinal length of the outsole) is 90 degrees ( 90°) and 0° (arrow C-0°). Then, as shown in FIG. 13, with traction members (134) arranged in overlapping circular patterns (136, 138) (a dual radial configuration) on the prior art outsole, low turf in the 90 degree direction. There may be a trench (arrow D-90°), but there is a pronounced turf trench in the direction of 0 degrees (arrow D-0°). Referring to FIG. 14, with traction members (140) arranged in a concentric circular pattern, there may still be grooves in this geometry and trenches in various directions. For example, trenches can occur in a linear direction (arrow D-x°) and in a rotational direction (arrow D-y°). Thus, as shown in FIG. 14, trenches can occur in both linear and arcuate patterns. As shown in FIG. 15, in yet another example of a prior art outsole, the traction members (140) may be arranged in a single logarithmic spiral, with grooves still formed. This geometry causes significant trenching in both the 90 degree (arrow D-90°) and 0 degree (arrow D-0°) directions.

More specifically, as shown in FIG. 12, if the traction members (130) are arranged in a collinear pattern and there is proximity between the members, this tends to create a turf trench. Second, the outsole construction of Figure 12 includes linear channels (132) in which no traction members are located, and these channel regions do not provide traction. A turf trench causes intensive damage to the turf, but poor traction results in no turf damage. However, the characteristics of turf trenches and urban areas are related. As the shoe slips and one traction member reaches the location of an adjacent traction member, traction is reduced as the traction member penetrates weakened or damaged turf. This sliding of multiple traction members through the same turf causes turf trenching. Meanwhile, the linear channel does not provide traction power. These linear channels contain no traction members, so the outsole (such as a rubber material) is in direct contact with the ground and has no grip.

In the present invention, as shown in FIG. 16 and discussed above, the outsole traction members (140) are arranged in an eccentric configuration, with each adjacent traction member positioned at a different radial location from a given center of rotation. This improves the shoe's traction on all surfaces. No channeling occurs, and little or no turf trenching for the amount of traction provided. The outsole of this invention does not have a linear channel configuration with closely spaced traction members that can create turf trenches. Rather, the outsole of the shoe of the present invention has traction members that provide optimum traction given the number of traction members in the outsole. In other words, these outsoles do less damage to the golf course for a given amount of traction.

Another advantage of the shoes of the present invention is that they can be worn while engaging in activities other than the golf course. For example, the shoes can be worn in clubhouses, offices, homes, and other ordinary places as casual "off-course" shoes. On all floorings and other surfaces, the outsole construction has a high traction force per volume of traction member for the amount of traction force provided. Additionally, the shoes are lightweight and comfortable, making them easy to wear while walking or during other activities. For example, the shoes may be worn while playing recreational sports such as tennis, squash, racquetball, street hockey, softball, soccer, soccer, rugby, sailing, and the like. Therefore, the shoe can be worn when engaging in many different activities on many different surfaces. This shoe offers unique traction and grip on both hard and soft surfaces.

Generally, the outsole described above comprises: (a) a forefoot region comprising first, second (intermediate) and third zone tiles with traction members; (b) one zone with traction members; a rearfoot region including first, second (intermediate), and third zone tiles with traction members, the outsole comprising: Note that only one example of an outsole that can be used for this shoe construction is shown. As previously discussed, the unique pattern of outer, inner and central zone traction members provides improved traction on both hard and soft surfaces. This geometry of the traction member helps provide the shoe with high traction force per volume of traction member and minimal turf trench characteristics for the amount of traction provided. However, it should be noted that other patterns of traction members may be used without departing from the spirit and scope of the present invention.

Furthermore, the traction members located on the outsole can have shapes different from those described above to achieve optimum traction force depending on the number of traction members. That is, the outsole can include a wide variety of traction members to maximize grip on a particular surface and reduce damage to that surface for the amount of traction achieved. Traction members may be of many different shapes including, but not limited to, annular, rectangular, triangular, square, spherical, elliptical, star, diamond, pyramid, arrow, cone, blade, and bar shapes, for example. can have Also, the height and area of the traction members per given tile on the outsole and the volume of the traction members can be adjusted as desired. As previously discussed, these variously shaped traction members are arranged on the outsole in a non-groove pattern. Various traction members and unique patterns on the grooveless outsole help achieve a shoe with high traction and low turf trench characteristics.

For example, referring to Figures 17a and 17b, two outsole constructions (142a, 142b) having different sets of traction members are shown. In Figure 17a, the outsole structure (142a) comprises a set of traction members (144) specifically designed to provide good traction on soft surfaces such as soccer pitches, lacrosse, rugby, soccer fields, etc. Equipped with These traction members (144) have specific shapes and dimensions to provide a high level of stability and traction on the course. This outsole construction helps to retain and support the medial and lateral sides of the golfer's foot as the golfer shifts his weight as he performs the golf shot. The outsole (142a) of this shoe provides excellent traction so that it is non-slip and allows the golfer to maintain balance.

Referring to FIG. 17b, the outsole structure (142b) is used for hard, particularly smooth surfaces such as boat decks, polished concrete and marble floors of sidewalks, painted surfaces of sidewalks, and the like. It has a set of specially designed traction members (146) to provide high traction on the surface. These traction members (146) have specific shapes and dimensions to provide good grip and traction on a variety of surfaces. For example, the shoes can be worn while walking, in the clubhouse, office, home, or during various recreational activities as described above. The traction member (146) maintains high contact with the surface and provides stability. The traction member (146) prevents slipping on hard, wet and smooth surfaces.

The outsoles (142a, 142b) are provided with different traction members (144, 146) as shown in Figures 17a and 17b to protect the outsole from on-course or off-course wear, i.e. hard and soft surfaces. Note that the wear of both can be optimized. However, in both outsole structures (142a, 142b), the outsole generally comprises the tread pattern described above, which includes (a) first, second (intermediate) and third zones; (b) a midfoot region containing tiles with traction in one zone; and (c) first, second (intermediate), and third zones of A rear foot region includes tiles with traction members. That is, although the types of traction members (144, 146) in the outsole are different, the geometry of the traction members resembles the non-grooved pattern described above. This pattern helps provide a shoe with high traction force per volume of traction member and turf trench characteristics with minimal traction force provided.
