An insole for use in athletic shoes comprises an upper layer, a lower layer laminated on the upper layer, and a shock-absorptive foamed material layer laminated on the underside of the lower layer at least at the heel portion. The upper layer has a hardness of 30.degree.-50.degree., and the lower layer has a hardness of 50.degree.-70.degree.. The shock-absorptive foamed material layer has a hardness of 50.degree.-80.degree..

A footwear insole member comprising a first portion the area of the upper surface of which approximately underlies the area of the longitudinal arch and a second portion the area of the upper surface of which underlies at least about 10% of the medial area of the heel and from 0 to about 50% of the lateral area of the heel, the border of the area of the upper surface of said second portion including about 10% to about 65% of the outer edge of the heel area, said first and second portions being l...

A weighted shoe insert (1) comprising a weighted base member (3), formed either as an integral portion of a shoe (8) or as a discrete insert sandwiched between an upper adhesively backed cover (2) and a lower adhesively backed cover (4). The base member 3 contains a series of perforations (28) and edge contours (17) which facilitate the shaping of the base member to conform with the human foot. In a second preferred embodiment, the base member is composed of a series of discrete elements (92) in...

A multi-layer shoe insole comprises a lowermost metal layer connected to a polyethylene foam layer via a film of polyethylene. An uppermost layer in the form of a felt material is connected to the polyethylene foam via a textile net embedded in a layer of synthetic resin. The insole is provided with a removably attached arch support and a removably attached heel cup. The layers of the insole are stitched to one another by a pair of threads which also serve to maintain the peripheral edge of the ...

An insole construction for shoe comprising an insole layer having a forward portion, an instep portion having upwardly flared walls defining a flexible support for the wearer's instep, and a heel portion having upwardly flared peripheral walls defining a heel cup and having an enlarged opening through which a segment of the heel portion projects, and an insert positioned below and secured to the insole layer.

A shoe insole having superior cushioning and comfort, good resistance to buckling, and excellent retention of cushioning properties after wear. The insole consists of three layers: (a) a bottom layer having compressive strength of at least 0.3 kg/cm.sup.2 at 40% strain, (b) an intermediate layer having less compressive strength at 40% strain than the bottom layer, and (c) a top layer constructed of fabric. The three layers are laminated together and shaped to fit inside of an article of footwear...

An insole structure having an outer contour corresponding to the shape of the sole of the foot has outer layers between which are located inner layers. The outer layers are made from a wear resistant material such as beechwood, and the inner layers are made from a lighter material such as poplar. The separately cut layers are glued together and shaped to form an anatomically contoured, substantially rigid structure.

A shoe insole includes a magnetized insole body formed of a mixture including rubber and magnetic poweder, the body having a first and second generally flat surface, and reinforcing sheets juxtaposed to each of the first and second surfaes. The insole has projections projecting from at least one of the surfaces, the projections being formed integrally with the body, and at least one of the sheets having projecting sheet portions projecting into such projections.

An insole device configured to fit the profile of the human foot to promote proprioceptive stimulation of the Golgi tendon organ. The midfoot section of the insole device has an asymmetric domed structure that is presented to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system. The asymmetric domed structure displays physical properties to catalyst muscle group balancing by using the body's proprioceptive feedback mechanisms. The asymmetric dome...

A shoe insole in the form of a separate insole or an integrated insole attached to the shoe is manufactured from a material with a consistency ranging from flexible to rigid. The upper surface which is generally smooth and which is formed to fit the sole of the foot has at least one local depression opening into the upper surface of the insole with a gently rounded rim along the entire length of its edge and having within this rim a base lying a few millimeters deeper than the intact upper surfa...
