The invention concerns an insole for footwear. The insole comprises a liquid-filled sole with a top sheet and a back sheet between which is formed at least one chamber with liquid. On top of the liquid-filled sole there is provided a net. The net creates a spacing between the top sheet and the foot, and the net is capable of containing air absorbing moisture from foot perspiration. By using a net on top of a liquid-filled sole it is achieved that the foot perspiration formed because of frictiona...

An insole (10) exhibits on its upper side facing the sole of the foot, in the region of the foot's reflex zones, flat, somewhat lenticular softly resilient massaging cushions (3,4,5,6,7,8), made of latex rubber for example, corresponding in contour and extent to the respective reflex zone to be stimulated.

In insole for promoting muscle activity has a first fluid cell confined to a toe area of the insole and a second fluid cell in the heel area. The cells are connected by at least one communicating duct which allows fluid to flow there between as a person walks on the insole. The duct has a valve system for controlling the flow as between the cells in a manner such that it may flow faster in one direction than the other.

An insole includes an abrasion-resistant fabric top covering adhered to a layer of molded modified dense polyurethane contoured to provide maximum shock absorption under those areas of the foot most subject to impact loading and a minimum thickness of polyurethane under the remaining portions of the foot. In addition, a series of grooves extending primarily parallel to the axis of the foot are formed in the lowermost surface of the shock absorbing polyurethane. These grooves provide volume into ...

An insole has a capillarily-conductive layer of hydrophobic fibers superimposed on a moisture-storing layer of absorbent fibers with a moisture-permeable bond between the layers.

An improved insole for a shoe comprising a plastic injection molded insole conforming to the shape of the foot and particularly the heel wherein a first oval cushion (typically 3 to 4 cm in length and 2 to 3 cm in width) of soft rubber is centrally located in a corresponding oval opening in the heel region and an optional teardrop shaped second cushion is attached to the top of the injection molded insole in the metatarsal region. Such an insole reduces fatigue, particularly in the case of prolo...

A foam latex insole includes a number of ribs on its undersurface. The ribs face the top-sole of a shoe when the insole is placed therein, and are formed of foam latex which is closed-pored and somewhat firmer than the foam latex which forms the continuous part of the insole. The ribs can be straight, curved or sharply bent, and form a labyrinth of ventilation channels between the top-sole of the shoe and the underside of the foot. The arrangement of the rib is such that a pumping effect is deve...

An insole includes a top wall and a bottom wall constructed from an air-impervious material. The top and bottom walls are heat-sealed at a durable side wall ridge to form an envelope having a heel, intermediate and front zones. A porous pad is contained within the envelope. Vent openings are provided only at the intermediate and front zones for ingress and egress of air from the envelope as the wearer walks on the insole. The total area of the vent openings in the front zone is greater than the ...

An insole for insertion in footwear having a laminated structure. The upper layer of the laminated structure is a split suede leather and the lower layer or laminate is resilient having an outer surface with frictional characteristics to prevent slipping relative to the footwear. Resilient padding is interposed between the layers in the metatarsal area and extending rearwardly at least to an area corresponding to the area of the long medial arch.

An insole includes a first layer made of a first slice foam material formed by a foamable polyurethane resin composition. A second layer is made of a second slice foam material formed by bonding together particles of comminuted previously formed foam material with a foamable polyurethane resin composition. The second layer is adhered to an upper surface of the first layer. The second layer has a thickness being greater than that of the first layer.
