Definitions

  • the technical solution concerns a footwear sole, formed of a combination of materials with different hardness and density, embedded in a polyurethane skeleton.
  • the midsoles consist of light-weight materials, to which a harder sole material is attached either by gluing or injecting.
  • the midsole is thus forming a compact layer between the bottom part of the sole and the foot or it is shaped into a form of a wedge.
  • Light-weight polyurethane (PUR) materials with the density of 300 - 600 kg/m 3 or light-weight ethylenevinylacetate (EVA) copoly ers with the density of 200 - 400 kg/m 3 or other foamy materials are conventionally used as the midsoles.
  • the sole is usually made of PUR material with the density of 600 - 1100 kg/m 3 , of cured rubber, of thermoplastic rubber or of polyvinylchloride (PVC).

  • a sole with sandwich structure of at least two layers with different density and/or hardness characterized in that the skeleton material with the density of 300 to 1100 kg/m 3 , and the hardness of 20 to 95 "ShA contains at least one layer wilth hardness and/or density different from that of the skeleton material, the layer being situated within the inner toe or heel part or under the whole foot, and the outer part is formed of the skeleton material, joining the shoe upper with the sole.
  • Density, hardness, thickness and design of the skeleton material depend on the specification of the footwear (sporting, orthopedic, health, working or outdoor footwear) .
  • the advantage of the technical solution consists in the increased comfort of the sole with the possibility to choose the size, form, hardness and structure of the materials in the heel or toe part or in the whole area of the sole under the foot. It is possible to make a sole with a number of layers of damping materials included in various parts of the sole.
  • tread structure in this solution essentially a layer structure is understood, wherein the treading layer may be of various shapes, and the layer of the material with different hardness and/or density is not identical with the area of the treading layer.
  • skeleton a part of the sole is understood, which is joining the shoe upper with the treading part of the sole.
  • the skeleton is formed of a skeleton material, which may comprise reaction polyurethane, natural or synthetic rubbers or other materials.
  • materials with density and/or hardness different from that of the skeleton material the following materials are understood: soft foamy materials, based on rubbers, polyurethanes, ethylenevinylacetate copolymers or other materials, or harder materials, based on rubbers, polyurethanes, polyvinylchloride (PVC), polyethylene (PE) or other hard materials with the density of 30 to 1200 kg/m 3 .
