Definitions

  • This invention relates to footwear and more particularly to sole units for boots and shoes.
  • U.S. Patent No. 4071963 discloses a sole unit for an article of footwear which sole unit has a sole portion and a heel portion and is moulded from a resilient material, a plurality of cavities formed in the upper surface of the sole portion and heel portion of the unit, a system of channels formed in the upper surface of the unit, which channels interconnect the cavities, and a bulge formed on the bottom surface of the sole unit at the location of each of said cavities.
  • the cavities are formed substantially wholly in the general thickness of the sole unit.
  • each of the cavities has a reduced cross-sectional area where is opened to the associated channel or channels.
  • the said reduced cross-sectional area may for example be approximately one-quarter of the maximum cross-sectional area of the cavity.
  • FIG. 1 there is shown a shoe 10 the upper 11 of which is lasted to an insole 12 made from leather, or a permeable plastics material or other suitable permeable material.
  • a moulded sole unit 13 is bonded to the insole and lasting margin 14 of the upper.
  • the sole unit is moulded from a resilient plastics material such as foamed polyurethane and has a multiplicity of cavities 15 formed substantially wholly within the general thickness of the sole unit.
  • the cavities are open to the top surface of the unit and are interconnected by a series of channels 16 which are also open to the top surface of the unit.
  • the cavities are grouped chiefly in the middle of the sole area and the middle of the heel area of the unit, and at least two channels communicate with each cavity.
  • the cavities are somewhat egg-shaped and there is a bulge 17 on the bottom surface of the sole unit at the location of each cavity, so that the pressure exerted by the foot on any bulge expels air from the associated cavity, and the action of walking pumps air from one cavity to another along the channels and in this way absorbs the shocks of impact of the foot with the ground.
  • perspiration from the foot of the wearer can pass through the pores of the insole and be evaporated by the air flow along the channels, so that improved dispersion of the perspiration is achieved.
  • Each cavity has a reduced cross-section where it joins the channels so that a neck 18 is formed which tends to restrict the rate of flow of air into and out of the cavities.
  • the diameter of the cavity at the neck is approximately half of the maximum diameter of the cavity.
  • the maximum diameter is typically in the range of 8 to 12 mm.
  • the bulges on the underside of the sole unit may have a height of 6 to 8 mm.
