Technical field

The present invention relates to the field of insole replacement of footwear.

In general, shoes, especially sneakers, have an insole located within the foot-receiving area when sold. The insole is positioned so that the user's foot rests on the insole while wearing the shoes. In general, such an insole is removable and can be replaced with a replacement insole that can utilize a variety of features beneficial to the particular needs of the user or user's feet.

Adequate degree of cognitive abduction, in normal gait (walking or turning the foot inside while running). However, some individuals have biomechanical properties that can cause excessive overgrowth and excessive internal rotation of the legs. It has also been reported that people with overturning tend to exhibit misalignment of the patella (knee bone).

Biomechanical considerations, including congenital higher quadriceps calves or Q-angles, have been reported to be more likely to cause patellar misalignment than men due to excessive foot casting, especially for women. Patellar misalignment is particularly associated with the onset of patellofemoral pain syndrome (PFPS), which is one of the most common causes of knee pain in women.

A device aimed at addressing the problems discussed above is described and claimed in U.S. Patent No. 7,721,467, assigned to Spenco Medical Corporation.

The present invention is an insole for placement within a shoe for use in reducing patella (knee bone) misalignment associated with overeating and reducing a user's knee joint stress. The insole has an upper seat and a support base cushion. The support base cushion has an area between the forefoot mid-cushion region extending from the toe end of the insole to the metatarsal region, and an arch to the heel extending from the metatarsal region of the insole to the heel end. The insole has a front foot cushion fixed to the mid-cushion area of the front foot. The insole also has a medial support cradle, a lateral support cradle, and a heel cushion all secured to the underside of the support base cushion in the area from the arch to the heel.

The inner support cradle is placed under the arch region of the foot and provides an elevated arch to the insole and, on the other hand, also provides support to the arch of the user's foot. In addition, the inner support cradle extends back around the lateral side of the heel, providing a semi-rigid support and structure in the heel cup of the insole. The inner support cradle reduces over-spin and knee stress.

The outer support cradle is a separate cradle that is positioned along the side of the support base cushion of the insole and provides semi-rigid support and structure to the side of the insole below the metatarsal area. The outer support cradle provides lateral support to the foot to reduce stress on the knee.

The heel cushion has a portion that extends upward from the bottom of the heel region of the foot in contact with the bottom of the user's foot and the bottom of the insole in use along the outer side portion of the heel end of the supporting base cushion. The structure of the heel cushion includes not only the lateral side heel end support but also the key impact zone for the heel strike by the user's feet, which is the later outer aspect of the heel "soft spot " ). The heel cushion works in conjunction with a harder inner support cradle to resist excessive rotation. This insole is particularly suitable for dealing with the asymptomatic tendency and knee stress problems of women.

In the process of walking or running, there is an insole for dealing with individuals, especially women, with problems of overeating and patellar misalignment.

The interlocking insole is for insertion into the bottom of the shoe of the user's shoe. It is to be understood that each leg normally has a right foot and a left foot, which are usually mirror images of each other, although the feet may have slight differences due to injury, wear and genetic characteristics. Thus, a pair of shoes typically have a pair of shoes that are mirror images of each other; One pair holds the right foot of the wearer, and the other pair holds the left foot. Also, the insole over the bottom of the shoe usually comes in pairs. One of the pairs of insole is configured to fit inside the shoe on the left foot, and the other is configured to fit inside the shoe on the right foot. For purposes of illustration, it is to be understood that only the right insole of the present invention is depicted and that the left insole is mirror image thereof.

Generally, the insole of the present invention has a first lower surface and a second lower surface configured to rest on the bottom of the user's shoe, a toe end and a heel end; (a) an upper sheet essentially extending to the full length of the inner bottom of the complementary user's shoe and having a toe end and a heel end and a foot receiving upper surface and an opposite lower surface; (b) Cushion region extending from the toe end of the insole to the metatarsal region and a metatarsal region extending from the metatarsal region of the insole to the heel of the insole, A support base cushion having an area from the arch extending to the distal end to the heel, or a rear region; (c) a front foot cushion having a first front foot cushion upper surface and a second front foot cushion lower surface fixed to the front middle-cushion region of the lower surface of the supporting base cushion; (c) an inner support cradle secured to the base cushion lower surface of the support base cushion; (d) an outer support cradle secured to the base cushion lower surface of the support base cushion; And (e) a heel cushion secured to the base cushion lower surface of the supporting base cushion.

More particularly, the insole has a forefoot region and an area from the arch to the heel. The area from the arch to the heel may also be called the rear area. In the second lower surface of the insole, the area from the arch to the heel further forms an inner support cradle attachment area, an outer support cradle attachment area, and a heel cushion attachment area.

The paw mid-cushion region of the insole includes a portion of the top sheet, a portion of the supporting base cushion, a front middle-cushion layer, and a front foot cushion from the foot receiving top surface of the insole to the second bottom surface of the insole. The paw mid-cushion region extends from the toe end to the metatarsal region and ends at the forehead region boundary.

The region or back region from the arch to the heel includes a portion of the top sheet, a portion of the support base cushion, an outer support cradle, an inner support cradle, and a heel cushion. The area from the arch to the heel extends from the metatarsal area or adjacent to the forehead area boundary to the heel end.

The inner support cradle is secured to the inner support cradle attachment region of the support base cushion in the region from the arch to the heel. The inner support cradle has a curved portion forming an arch support of the user's foot and an inner heel support cup portion. The inner support cradle has a ridge with a peak at about 2.2 to 2.9 cm +/- 0.2 cm as measured from the support surface (the shoe contact area in use) to the highest point of the inner arch. The ridge is configured to lie adjacent to the user's arch when the insole is in use. The inner heel support cup portion extends from the ridge to the back side and partially surrounds the heel portion of the insole and thus forms a heel support cup on the inner side surface of the insole.

The outer support cradle is secured to the support base cushion in the outer support attachment region.

The outer support cradle has a first shoe inner bottom contact portion and a second side portion extending upward from the first shoe inner bottom contact portion to create a support on a side surface of the user's foot. The inner support cradle extends upward from the bottom portion of the first shoe inner portion to a height of about 2.15 to 2.2 cm. The outer support cradle extends from the heel end essentially in close proximity to the forefoot region boundary but does not extend to the heel end. The outer support cradle has a rear end adjacent the heel cushion attachment region of the support base cushion.

The first shoe bottom contact portion of the outer cradle has an upper boundary along the shape of the front cushion and provides a rounded area (which in one embodiment may be essentially semicircular in one embodiment) to be placed under the metatarsal portion of the user's foot during use . Preferably, the rounded area lies adjacent to the metatarsal cushion preferably integral with the supporting base cushion. This metatarsal cushion may be integral with the support base cushion by providing indentation in the mold used to form the support base cushion. It appears as an elevated area (or convex protrusions) when viewed from the top of the insole.

The indentation will be filled with the polymer during the manufacturing process and thus the upwardly extending portion of the support base cushion will be formed. Alternatively, but less preferably, a separate metatarsal cushion is secured to a portion of the top surface of the base cushion, and then both structures are secured to the top layer.

The first shoe bottom contact portion of the outer support cradle gradually decreases in width as it extends from the round area toward the heel cushion attachment region. This allows the support base cushion to be exposed in the area between the inner support cradle and the outer support cradle to provide resilience to the exposed area. The exposed area will directly contact the inner bottom of the user's shoe during use.

A heel cushion is secured to the supporting base cushion in the heel cushioning area. The heel cushion has a first inner shoe contact portion and a second side portion extending to the upper side. The structure of the heel cushion provides a "soft seat" which is the posterior lateral side of the heel in the critical impact zone for the heel grounding by the user's foot. The ductile outer boundary (ie, the side section extending to the upper side) is compressed upon contact to attenuate the impact at the heel ground and adjust the ground repulsion. Thus, it works in cooperation with a harder inner support cradle and resists in excess of the revolution. The lower boundary, which is the softness of the heel cushion, serves to buffer the central heel area. Preferably, the first inner shoe contact portion of the heel cushion has a shape similar to that shown in Fig. This shape provides the optimum ductility for the critical impact zone.

The width of the first inner shoe contact portion is from about 37 mm to about 48 mm ± 0.50 mm from the smallest size insole to the largest size insole. The length of the first inner shoe contact surface from the foremost to the trailing edge is from about 38 mm to about 49 mm +/- 0.50 mm. For a typical female size 11-12, the preferred length is 49 mm and the width is 47.70 mm. The depth of the heel cushion from the first inner shoe contact area extending upward toward the foot contacting surface is in the range of about 3.0 to about 3.5 mm ± 0.50 mm. For a typical female size 11-12, the preferred depth is 3.5 mm.

A side portion extending to the second upper side of the heel cushion forms an outer portion of the heel support cup while the inner support cradle described above provides an inner portion of the heel support cup and cushion, And provides elasticity to the outer portion. The side portion extending to the second upper side of the heel cushion surrounds the outer lateral side of the insole to a region substantially adjacent to the second side portion of the outer supporting cradle.

The support base cushion is preferably made from a buffer material. Most preferably, it is made from polyurethane ("PU") and has a hardness of about 40 Asker C ± 3.

The inner support cradle is made from a material that is fairly rigid, such as thermoplastic polyurethane (TPU). The preferred hardness is 64 Type D ± 3. As long as the properties are similar, other materials may be used. The outer support cradle is made from the same or similar material used for the inner support cradle.

The inner support cradle and the outer support cradle preferably have a thickness in the range of 0.5 mm to 1.5 mm. The preferred thickness is 1 mm because it also provides sufficient stability and support but also allows the cradle to be bent with the insole.

The front foot cushion is preferably made from a buffer material. Most preferably, it is made from ethylene vinyl acetate ("EVA") and has a hardness of 21 ascur C ± 3.

The heel cushion preferably comprises a thermoplastic rubber gel ("TPR").

Although other gels may be used, it is preferred that the gel used has the properties described in the following paragraphs.

The Shore / Asher hardness test provides a measure of hardness. In a most preferred embodiment, the heel cushion is 30 asqueath C 3.

The Shore / Asher hardness is measured in commercially available durometer. The material to be tested is placed on a rigid, flat surface. The as- cabor tester is equipped with a "C" scale and an appropriate indenter type, typically hemispherical. The as- cabor tester is placed on the material to be tested without additional pressure. The needle is deflected to provide a reading.

The topsheet is fabricated from an insole or foot profile with fabric sheet material. The fabric may be selected from any fabric that is placed adjacent to the foot in use and that can be laminated with the supporting base cushion layer. The preferred sheet material is a polyester fabric, but other fabrics such as brushed nylon and others can be used. Optionally, a fabric that reduces friction between the material and the human foot may be used. The fabric can have any desired color.

Most preferably, an antimicrobial fabric, such as an antimicrobial polyester, is used. Antimicrobial fabrics are preferred for inhibiting odor-causing bacteria. Fabrics having these properties are commercially available. One suitable fabric may be obtained from SILPURE ™ technology fabrics using silver technology for antimicrobial purposes and through Thompson Research Associates, Toronto, Canada. In a preferred embodiment, a fabric sold under the trademark Ultra-Fresh Silpure FBR-5 is used, which provides for the inhibition of bacterial growth even after extensive washing. Other types of antimicrobial techniques, preferably other fabrics that utilize long-term sustainability, may be used.

The support base cushion, the heel cushion, and the inner cradle and the outer cradle are preferably formed through an injection molding method and fixed to each other. Preferably, the mold used to make the insole has a two-sided profile. This enables faster assembly and thus eliminates the need to replace the mold during the injection molding process. A support base cushion is formed on one side of the mold and a heel cushion is formed on the opposite side of the mold. Although standard injection molding assembly line methods are preferably used, any molding method that produces a structure having the properties contained herein can be used and is known in the art.

The total thickness and size of the insole may vary depending on shoe size, application, and whether the insole is removable or permanent insole. The length of the insole of the female is in the range of about 231 mm to 299 mm, the width in the vicinity of the toe region is in the range of 76 to 99 mm, the maximum thickness is in the range of about 24 to 30 cm, About 21.5 cm. In a typical female size 11-12, the length is approximately 298 mm, the width is approximately 69 mm near the heel, and 98.4 mm near the metatarsal area. Size 11 - 12 The height of the insole is in the range of about 4 mm to 21.5 mm from near the heel near the toe. The length and width of the insole will depend on the shoe size that is intended to place the insole, but at the same relative area the thickness will be similar to a typical insole.
