Definitions

  • the invention relates to footwear with a sewn-in inner sole and an attached synthetic or rubber outer sole, p rticularly a foamed polyurethane outer sole, as well as an intermediate sole between the inner sole and the outer sole.
  • Shoes are manufactured either in crimped or pinched form or by sewing in the inner sole. While shoes with a pinched supporting layer generally have a stiff inner sole or a stiff intermediate sole, shoes with a sewn-in inner sole are flexible. This flexibility, however, proves to be disadvantageous, particularly in street shoes. In order to correct this deficiency, such shoes generally are provided with supporting layer reinforcements or intermediate soles. Various reinforcements are known which are placed onto the inner sole before soling.
  • suspension devices may, for instance, be straps or slots.
  • FIG. 1 is a perspective view of a shoe with an inner sole and an intermediate sole held thereon by straps connected to the upper of the shoe;
  • FIG. 2 is a perspective view, similar to FIG. 1, but showing a modification in which the intermediate sole is held by straps cut off the inner sole;
  • FIG. 3 is a perspective view, similar to FIG. 1, but showing a modified two-piece intermediate sole.
  • a shoe 1 has an upper 2 to the lower part of which there is sewn an inner sole 3 along the line 4. Below the inner sole 4 there is provided a reinforcement layer that forms an intermediate sole 5.
  • the intermediate sole 5 is held against the inner sole 3 by straps 6, 7 and 8.
  • the intermediate sole 5 may be made of cardboard, pressed leather fibers, cellulose fibers, or the like.
  • the upper 2 with the sewn-in inner sole 3 is provided with straps, 6, 7 and 8. Thereafter the intermediate sole 5 is moved between the straps 6, 7, 8' and the inner sole 3. Then the last (not shown) is mounted on a sole form and subsequently the outer sole, for instance made of polyurethane, is foamed up.
  • FIG. 2 illustrates a modification wherein the intermediate reinforcing sole 5 is placed in slots that are formed by cut out suspension straps 9 and 10 in the inner sole 3.
  • an inner sole 3 of several layers may be used and only the outermost layer be slotted to form the suspension straps 9 and 10.
  • FIG. 3 there is held in the region of the ball of the foot a first intermediate reinforcing sole portion 11 and in the heel region a second intermediate reinforcing sole portion 15 that is not connected to the portion 11 and is spaced therefrom for a distance across the middle of the inner sole 3.
  • the portion 11 is held by straps 12 and 13, while the portion 15 is held by a strap 14.
  • the straps 12, 13 and 14 are connected to the upper 2.
  • Footwear comprising:
  • suspension means operable to hold up to and throughout soling said intermediate sole means in predetermined position adjacent said inner sole, in which position the internal surface of said intermediate sole means engages at least the major portion of the outer surface of said inner sole, prior to the mounting of said outer sole.
  • said suspension means comprising at least one strap connected to said upper and engaging said intermediate sole means.
  • said suspension means comprising at least one strap cut from at least the outermost layer of said inner sole and defining with said inner sole a slot, said intermediate sole means being disposed in said slot and engaged by said strap.
  • said holding means including a plurality of straps engaging the external surface of said intermediate sole means.
  • said intermediate sole means including a plurality of intermediate sole portions, said suspension means including at least two straps,
