A shoe liner, which in one embodiment comprises a covering layer having fine nodules, a pad underneath the layer for supporting the arch of the foot, a support part supporting the foot arch, a heel bone support with a kidney shape cooperating with the support part to form a heel through whose rear limit is formed by the heel bone support; and in another embodiment, the shoe liner comprises two outer layers between which is sandwiched a contoured arch support that extends under the central portion of the wearer's foot.
An inner sole with a cushioning layer of polyurethane foam, with compression set less than 10%, laminated to a thinner layer of thermoformable polyethylene foam, which serves primarily as a vehicle for shaping the polyurethane.
A portable collapsible bed, comprising a mainframe having opposite ends and having legs adjacent each end. A subframe having opposite ends has one end pivotally connected to one end of the mainframe. The subframe has collapsible legs spaced a substantial distance from the other end of the subframe but closer to that other said end than to the one end of the subframe. The legs of the subframe define a seating face. The legs of the subframe are releasably secured in a first position at a substantial angle to the subframe, and are mounted for swinging movement from that first position in a direction away from the one end of the subframe into a second position in which the subframe legs lie against the other end of the subframe, that is, the end remote from the mainframe.
An insole the material for which is made from a elastomer showing gum-like elasticity under the normal temperature, and which is provided with a wedge-shaped profile, irregularities, curves, and the like for the purpose of making the sole incline or correcting the state of unevenness thereof. It is used by being inserted inside shoes, slippers, sandals, etc., or by being worn on the sole of the foot with the aid of socks, simple holders or band bodies being molded integrally with the holders. Further, it may be made by utilizing a foam-formed body, or by boring small holes for air permeation therein for retaining warmth or making it light-weight.
A body warmer for use in footwear is disclosed which is prevented from slipping in footwear and is capable of warming a desired portion accurately, and which includes an exothermic composition capable of generating heat in the presence of air, an air-permeable bag accommodating the composition, and an air-tight bag sealingly enveloping the air-permeable bag, the air-permeable bag being formed with a non-slip layer in at least a portion thereof.
A lightweight, flexible gymnastic shoe is disclosed. The shoe includes an upper formed of a lightweight synthetic fabric. A relatively broad closure strap has a first end fixed to a medial inside surface of the upper in the area of the arch and a second free end for detachable attachment to the medial outside of the upper. A hook and pile fastener selectively fastens the second end of the closure strap to the upper. A sole is attached to an outer bottom surface of the upper, and is formed of a relatively thin resilient material located only below the toe, ball and heel areas. A liner is located inside the upper and extends along substantially the entire length of the inside top surface of the upper. The liner is formed of a relatively low density cushioning material. A metatarsal pad is located along the liner only in the area of the first and second metatarsal heads of a wearer's foot, and a heel pad is located along the liner in the heel area. The pads are formed of a shock-absorbing material different from and having a higher density than the material of the liner. An arch support is formed of a built up area of material positioned below the medial arch area.
