An insole insert for application into a shoe, and which is formed as a laminar material of various layers of paper, polymer, stranded thermoplastic or thermosetting material, foams of select consistencies and texture, in addition to a felt or microfiber type of upper layer, to add to the cushioning and softness of the insert, when applied. The insert, when subjected to heat and pressure, particularly pressure applied by the foot, conforms to the contours of the foot, and sustains such, even afte...

A podiatric insole in the form of a flat flexible envelope of the outline of a wearer's foot and containing a liquid or semi-liquid flowable cushioning medium. A transverse wall divides the interior of the insole into front and rear chambers, the transverse wall extending along the forward edges of the metatarsal pressure points of the foot of the wearer. The rear chamber has longitudinal walls directing the flowable medium forwardly and rearwardly in such chamber and the front chamber may also ...

An insole for use with footwear includes a first layer including a heel portion of a first thickness, a mid portion connected to a front section of the heel portion and having a substantially constant thickness which is much less than the first thickness, and having an upward curvature, an upper surface extending along the mid and heel portions and on which a person stands, and a lower surface extending along the mid and heel portions, the lower surface including a shallow recess in the mid port...

An insole assembly for a shoe or other article of footwear. The assembly includes a soft, cushioning foam blank having an upper surface which is contoured to engage the plantar surface of a foot, and a thin, substantially rigid, resiliently flexible cap which is mounted to the bottom of the blank so as to extend around the heel end and forwardly along the medial and lateral sides thereof. The rigid cap includes an upstanding wall which engages and buttresses the perimeter of the foam blank, and ...

A composite insole for shoes is disclosed including a generally rigid upper layer and a resilient and compressible lower layer which underlies the upper layer throughout and is laminated thereto. Spaced upper elements of a shoe are impressed through a binding element, attached to the insole, into the resilient and compressible lower layer in order to provide a substantially uninterrupted bottom binding surface to which a shoe outsole is attached. Heel attachment, without openings, and with a smo...

A sock combined with an insole comprises an insole; at least one surface of the insole is formed with elastic hooks; the hooks being deformed due to an external force, but restoring as the force disappears; and a sock having a sock body and an opening; the sock body having a sock sole; whole or part of the lower bottom of the sock sole being formed with curl wires for grasping the hooks so that the sock is tightly secured to the insole to avoid the relative motion between the sock and the insole...

An electrically heated insole construction adapted to be fitted into a shoe or boot, the insole having a layer of plastic mesh material with the openings in the mesh providing air insulation spaces, and a layer of plastic electrically insulated material overlying the mesh material in a toe portion of the insole and having an electrically conductive circuit printed thereon.

A shoe include an outsole, an insole, an upper, and a reinforcement member. The insole is attached to the outsole along an upper surface thereof and is provided with at least one aperture extending through the insole to the upper surface of the outsole. The upper includes an elongate element extending into the aperture. The reinforcement member is attached to the insole at least along an upper side of the aperture for protecting material of the insole from stresses arising from movement of the e...

A shoe insole structure which includes a non-springy, acceleration-rate-sensitive viscoelastic cushioning layer carrying, on its upper surface, a low-friction, abrasion-resistant, load-distributing, moisture-wicking overlayer.

An insole construction for footwear comprising a base member, an intermediate member formed of a foam and having a plurality of substantially uniformly spaced raised cushioning elements on the upper surface thereof, and a flexible cover member surrounding the intermediate member and extending beneath the base member. The intermediate member preferably is formed of a foam such as polyurethane foam. The raised cushioning elements are of a height of approximately 6 millimeters above the upper surfa...
