A cushioned insole (10) has an upper layer (12) and a lower layer (14). The layers have a toe area, a heel area, an upper surface and a lower surface. The insole has a cushion (28) disposed between the lower surface of the upper layer and the upper surface of the lower layer in the toe area of the layers. In the heel area of the layers, a tack board (30) is disposed between the upper and lower layers. A rib (40) is attached to the upper surface of the upper layer and to the lower layer by stitch...

An insole for a shoe, which massages the reflex zones of the sole of the foot, has a flat basic sole (1) which matches the contour of the shoe and cushion-shaped elevations (5) associated with the reflex zones to be massaged. The elevations (5) are integrally formed on the basic sole (1) and consist, like the basic sole (1), of elastic foamed material having a Shore A hardness of 30.degree. to 45.degree.. The height of the summit region (7) of an elevation (5) above the upper surface of the basi...

An insole for a shoe made of foam resin containing fine bubbles, the thickness of which increases from the portion corresponding to the arch of the foot to the trailing end of the heel to give a slope on said insole, the bottom edge or corner of the heel is cut to provide cavities between the cut surface of the insole and the inner surface of the shoe to allow the insole to be deformed into said cavity due to the load on the insole for guarantee of cushion.

An insole structure for footwear comprised of upper and lower surfaces which form one or more internal cavities within the body of the structure, the cavities so formed containing a fluid such as water, air or a gel, providing thereby a durable and comfortable means for cushioning and supporting the feet inside footwear such as shoes, sandals, slippers and/or boots. The present invention may find embodiment in (i) a flexible contoured insole designed for insertion into conventional footwear or (...

A shoe insole is composed of a toe portion, a sole portion and a heel portion. The insole has a thickness of 2 mm or more. The toe portion and the sole portion have a hardness value ranging between 20 and 45 degrees in the Asker Type C, whereas the heel portion has a hardness value ranging between 30 and 50 degrees in the Asker Type C. The hardness values of the toe portion, the sole portion and the heel portion are decreased by at least 5 degrees for an increase in the thickness of the insole b...

An insole for articles of footwear comprises an apertured top layer formed from a non-absorbent, thermally non-conductive thermoplastic material which is affixed to a stabilizing layer formed of a non-woven material. The stabilizing layer, in turn, is affixed to a barrier layer and/or a cushioning layer to form insoles for articles of footwear intended for different activities.

An insole for a shoe or boot produced by molding together a stiff outer plastic shell, a dual foam inner layer of rubber-like material and a fabric upper layer engaged by the foot. A more dense foam is provided for the inner layer at the arch of the foot. The shell is feathered or thinned toward the fore foot area and extends only to the ball of the foot. The shell is provided with a cut out at the heel and a pad secured to the insole at the cut out cushions the heel at the strike position.

An odor and moisture absorbing insole or insock for covering the inner sole of footwear has a bottom open cell latex foam layer with a smooth bottom skin for engaging the bottom inner sole of footwear, an intermediate noncellular latex layer with discrete activated charcoal particles dispersed throughout and locked in this layer, a porous slippery abrasion resisting top fabric layer protecting the foot or sock of the wearer against discoloration or irritation, and spaced perforations extending t...

A laminar insole for footwear has a top, porous, non-woven, non-absorbent layer or mat of plastics material fibers, an intermediate moisture absorbing paper or other non-woven layer impregnated with deodorizing material, such as activated charcoal, coated on the paper fibers, and a bottom open-cell plastics foam cushion layer cured in-situ on the intermediate paper layer. The top and intermediate layers are stitch bonded together by pushing fibers from the top layer into and through the intermed...

A cushion insole for shoes comprising a unitary combination material that includes a skin of wear material which is integral with a layer of resilient foam material, the foam material being wrapped around and adhered to a boardlike support which is relatively rigid and stiff. The insole may be adhered to a sole.
