Air permeable wear-resistant insoles comprising a web or matt layer of fibres, bonded with active carbon and bonded thereto a wear-resistant fabric which is different from and has greater wear-resistance than said web or matt layer, in which the ply bond strength of the said bond between the wear-resistant fabric and the said matt or web layer is greater than the ply bond strength of the matt or web layer itself, said insoles being produced by forming a web or matt of fibres loaded with active c...

A shoe insole that will allow plantar flexion of the wearer's foot in an upward direction but will inhibit such flexion in a downward direction past a normal horizontal condition. The insole includes a rigid first member that extends from a toe end to a rear edge situated midway between the heel and toe of the wearer's foot. A flexible second member overlies the first rigid member and is hinged thereto at a transverse edge located between the toe and rear edge of the first plate. The second plat...

This invention pertains to insoles and lasts for footwear. The insole has one or several protrusions which fit correspondingly disposed cavities in the outer sole thus assuring correct alignment of the outer sole and the insole at assembly. Lasting hooks are located around the insole which help to improve string-lasting and make possible a novel lasting method in conjunction with holes in the lasting margin of the upper. The last has two registration pins, one of them is firmly, the other one re...

A sneaker or canvas shoe having an insole comprising a soft pad which is encased in a sealed film envelope to prevent the pad from absorbing moisture, odors and contamination. The envelope includes a chamber disposed beyond an end of the pad into which air can be forced, from the area of the envelope surrounding the pad, when pressure is applied to the insole by the weight of the wearer of the shoe. A part of the air chamber is heat sealed to the toe portion of the shoe, during the manufacture o...

Insole formed as a composite of a network of reinforcing fibers embedded in a matrix of a thermoplastic material having a softening temperature in the order of 90.degree. C. and retains its softening for a reasonable time at a lower temperature that is not uncomfortable to the human skin. The insole is formed to the shape of the bottom of the wearer's foot by placing it while still soft in the shoe and allowing it to harden while being subjected to the wearer's standing weight.

A lasting insole for a welted shoe. The lasting insole includes: a support layer; a rib for connecting an upper and a welt to the support layer; and connecting structure for connecting the rib to the support layer. The connecting structure is located between the rib and the support layer. Stress encountered during use of the welted shoe is shifted away from the connecting structure. Preferably, the stress is shifted by spaced apart grooves. The grooves are formed by projections which are pressed...

A shoe insole formed by a resilient base piece adapted to be disposed primarily at the heel area and having a cupped peripheral wall. A heel piece is disposed within the base piece and constructed for improved shock absorption at the heel. A top cushioning layer is provided overlying the resilient base piece and heel piece. The top cushioning layer extends over the base piece from the heel area thereof and forwardly of the base piece so as to principally underlie the foot ball and toe area.

An article of footwear is disclosed. The article comprises an insole (3) and a sole element (9) secured to the lower surface (11) of the insole (3). The sole element (9) is formed from a material capable of absorbing impact energy. The article is constructed so that the sole element (9) extends through an opening (15) in the insole (3) and projects to or above the upper surface (7) of the insole (3) and forms a load transfer region for transferring load between a foot of a wearer of the footwear...

A custom molded insole for supporting the human foot in a ski boot or other footwear is disclosed. The insole is a one-piece, thin, contoured blank of semi-rigid, bendable, resilient material molded to include the complete detail of the full plantar surface of a foot. The insole provides a four-point contact with a supporting surface or ski boot at the heel, great toe, and at least two spaced metatarsal heads to provide natural balance and proper dynamic positioning of the foot and immediate ene...

A footwear heel disposed between the foot contacting and ground contacting surfaces member, preferably part of a complete heel to toe device, comprising in transverse cross-section a lower posting portion at the bottom surface sloping upwards towards the medial side wall and being less elastically compressible than the remaining upper portion of said member, the lateral and medial sides of said cross-section being substantially symmetrical with each other whereby the thickness of the upper more ...
