A sole insert for use in footwear includes a toe plate portion, a metatarsal portion and a heel portion all formed in an integral molded member. The heel portion includes a thickened block-type reinforcing frame merging smoothly into a similarly constructed-type metatarsal portion of reduced thickness which in turn merges into the flat toe portion. The toe portion includes laterally extending weakened portion such that the insert will resist to torsional twisting but will flex about a lateral axis located in the toe portion.
A shoe structure which provides a comfortable, lightweight, strong and stable support structure which provides cushioning and shock absorption in the heel and a smooth transition from the midfoot to the forefoot for a high heel shoe. The shoe structure comprises a molded shank member having a midfoot portion and a heel portion having an integrally formed basket for receiving a heel pad, a shank stiffener embedded in the shank member, and an insole board having a forefoot portion and a midfoot portion, the midfoot portion having upper and lower layers between which the midfoot portion of the molded shank member is enclosed.
The present invention relates to a sole, especially for a sport bdot, adapted to sports that require a foot movement or to gliding sports. The sole, especially an external sole, is constituted by a front part and a rear part. The rear part covers at least the base of the heel zone and is rigid and substantially non-flexible. Preferably, the rear part extends substantially up to the so-called metatarsophalangeal bending zone. The present invention also relates to a method for manufacturing a sole, especially a sole such as described hereinabove. In addition, it relates to a boot having a sole such as described hereinabove.
A boot for a ski or an in-line roller skate has a flexible upper and a sole allowing the foot to flex during walking. Its sole has a rigid part in the rear region of the boot, over about one half of the length of the sole, this rigid part being designed so as to form an interface between the heel and a binding of the ski or in-line roller skate. The interface may be standard, that is to say independent of the boot size.
