A sock is provided having a first compression area 1 which raises the compressive force in a wale direction from a position A behind the toe area of a sole portion of the sock to a position C which includes the boundary between an arch portion B and a heel portion 6, a second compression area 2 provided on the periphery to raise the compressive force in a course direction at the position A behind the toe area, a third compression area 3 provided on the periphery to raise the compressive force in a course direction at an ankle portion D, and a fourth compression area 4 provided on the periphery to raise the compressive force in a course direction from the position C which includes the boundary between the arch portion B and the heel portion 6 to a position E at the base of the instep portion. The advantageous effect of protecting and restoring the shape of the longitudinal plantar arch is produced by the various compression areas, thereby stabilizing the position of the various compression areas while the sock is worn.

A composite footwear insole has a front portion (2) designed to interact with the foot at the metatarsal region and at least partly at the plantar arch, and a rear portion (3) designed to interact with the heel. The rear portion (3) has at least one layer (4) of gel material whose size is at least substantially equal to that of the rear portion (3) to uniformly support the heel and absorb stresses acting thereon.

A sole for footwear, formed by an upper surface which, on at least part of the heel region and the plantar arch region, at its outer edge, is lower than its inner edge. The highest point of the upper surface is arranged approximately at the radiographic projection of the scapho-cuneiform joint of the foot of the user on the sole.

An inner sole includes a heel air bag for supporting the heel and a first arch air bag for supporting the plantar arch which is connected to the heel air bag through a passageway. The heel air bag and the primary arch air bag are coupled to the bottom surface of the inner sole. A second arch air bag is disposed over the first arch air bag to communicate with the primary arch air bag. When the heel air bag is pressed, air pressure is uniformly applied to the second arch air bag through the first arch air bag.

A dynamic ventilation system for socks including an ergonomic and asymmetric strip structure (3) which contains the plantar arch so as to create internally an integrated aerating sector (4). Further, the system has a first structure with a transparent zone in which an air circulating system is created that is provided for regulating the temperature of the foot and leg, containing a certain quantity of air between skin and sock so as to create an “air chamber” with an effect of insulating from the external environment and a second structure having a plurality of contact sectors (5) that have greater support on the skin that are interrupted by free portions (6) for the passage of air. The system further includes a pair of ribs (11) that create a passage / tunnel for circulating air in addition to increasing Achilles tendon protection in which each rib is a cushion that fills with air.

It is intended to provide a sock which offers a comfortable fitting feel without causing fatigue, congestion and so on even over prolonged wearing. Namely, a sock having such a length as at least covering from the toe to the ankle and being knitted with knitting yarn, wherein a knitted fabric made of a face yarn and a back yarn is provided in the inner half of the plantar arch area in the foot sole and an auxiliary yarn is further inserted together with the face yarn to thereby present a constricted and less expandable fabric.

The present invention proposes a method for making cushioning and shock-absorbing insoles, including 1) fixing the arch support layer on the arch of the mold; 2) baking the memory shock-absorbing layer until it softens; 3) softening the softened The memory shock-absorbing layer is placed in the insole forming groove of the mold, the arch support layer is set at the arch of the memory shock-absorbing layer, and a hot-melt film layer is placed between the arch support layer and the memory shock-absorbing layer, and the mold is placed on the insole The bottom in the forming groove is also provided with a vacuum suction pump; 4), the vacuum suction pump carries out surface suction texture treatment to the bottom surface of the arch support layer and the forefoot and heel of the memory shock absorbing layer respectively. The arch support layer is thermally compounded on the arch position of the memory shock-absorbing layer according to the temperature and pressure of the blister and the heat-melt effect of the hot-melt film layer, and the memory shock-absorbing layer compounded with the arch support layer is obtained; 7), Cutting step, 8), put the memory shock-absorbing layer compounded with the support layer into the injection mold and inject the insole body.

The present invention provides a pad capable of effectively curbing fall of a plantar arch. A pad in accordance with the present embodiment, for supporting the plantar arch of a sole of a foot, is provided in a supporter, made of a stretch cloth, including a plantar part and an instep part, which is connected to the plantar part. The pad is located in the plantar part and has an apex, which is provided at a position corresponding to an area in the sole of the foot which area corresponds to the navicular bone of the foot.

The invention provides a making method of a ventilation buffer shoe pad. The method comprises the steps that material selection and cutting are carried out; a foot arch supporting layer bottom surfaceV groove is formed, composite groove suction is carried out, a lower layer memory film and an upper layer memory film are subject to high-frequency compositing, a damping ventilation memory film layer in the shoe pad shape is obtained, and the damping ventilation memory film layer composited with the supporting layer is placed in an injection mold to be subject to injection molding to form the shoe pad body; the formed shoe pad body is subject to demolding, and trimming, and the damping ventilation shoe pad is obtained. The whole manufacturing process is simple and ingenious, the whole shoe pad is firm in connection, and the forming efficiency is high.

The present invention provides an upper part (U) of each of sports shoes having a first opening (1) surrounding the instep of a foot and allowing the foot to be upwardly projected therethrough when the sports shoes are worn and a second opening (2) closed by a tongue piece (T) which are arranged continuously to each other, comprising an inside extension part (51) covering a part of the inner surface of the plantar arch of the foot, an outside extension part (50) covering a part of the outer surface of the hypothenar of the foot, a front part (3) disposed at the front of the both extension parts (50) and (51), and a rear part (4) disposed at the rear thereof. The extension parts (50) and (51) cross one side-face of the upper part (U) starting at the upper surface of a sole (S) to the second opening (2). The Young's Modulus of the extension parts (50) and (51) in the foot longitudinal direction (L) is set smaller than the Young's Moduli of the front part (3) and the rear part (4).
