Definitions

  • ABSTRACT [30] Foreign Application Priority Data Feb. 4, 1972 In a footwear, particularly a ski boot, which has an Sweden......................... 1334/72 upper of cellular rubber attached to a sole of plastic [52] US. 36/25 AL material, there are provided leather joining elements [51] in the zones of the toe portion and the heel portion. Each joining element is sewn to the upper and the sole h c r. a e
  • the present invention relates to footwear, especially ski boots having an upper of cellular rubber, for instance of synthetic styrenel-butadiene-latex foam rubber with closed cells, and having a sole of plastic material, for instance a blockcopolymer of styrene and butadiene.
  • the present invention has for its purpose a boot design eliminating the disadvantages hitherto encountered in using. the cellular rubber upper material, per se suitable for boots, namely the difficulty of connecting it with the sole and even the stiffness of the material.
  • this purpose is attained by connecting the cellular rubber upper which is glued or sewn to the sole with the sole by means of a joining element of leather at the parts which are exposed the most to stress and strain by walking or skiing, namely the toe portion and the heal portion, this joining element being sewn with seams to the toe portion and the heel portion of the upper and of the sole.
  • the disadvantages of the stiffness of the cellular rubber material are eliminated by having the shank portion of the boot made of a relatively soft leather, preferably containing an insert of foam rubber, which portion is sewnon the upper of cellular rubber by a seam. In this manner the stiff cellular rubber material is prevented from engaging the ankle portion so that galls are avoided at this vulnerable portion.
  • FIGURE illustrates the invention in a perspective, partially cutaway view.
  • the boot is shown having a sole 1, an upper 2 and a shank 3.
  • the sole material is a block polymerizate of styrene and butadiene having the advantages that the sole material does not become brittle in the cold and that it has low water absorption.
  • a link consisting of spring steel and making the arch portion of the boot more rigid is inserted between the sole and the leather insole.
  • a toe joiningand reinforcing element 4 of leather is sewn on one hand to the upper by means of a seam 5 and on the other hand to the sole by means of a seam 6.
  • a wedge 7 known per se is inserted between the leather joining element and the sole.
  • the leather joining element extends from the tip of the toe of the sole and rearwardly along the whole toe portion of the boot and upwardly to almost the full height of the toe portion.
  • a similar Giring and reinforcing element of leather 10 is inserted between the heel portion 8 of the boot and the heel 9.
  • This heel joining element is sewn to the upper by means of a seam 11 and to the heel 9 by means of a seam 12.
  • the seam of the toe joining element as well as that of the heel joining element extend all through the sole so that a reliable connection is obtained between the upper and the sole.
  • the shank portion 3 consists of an envelope 13 of soft skin having an inlay of foam plastic 14.
  • the shank portion 3 is sewn to the cellular rubber upper by means of seams 15, and the two skin strips which enclose the foam plastic filler 14 are sewn together by means of a seam 16.
  • the invention provides a boot the upper of which consists of a water proof, low weight and porous cellular rubber material which in a reliable way is connected to the plastic sole by means of a leather toe joining element and a heel joining element also of leather, the boot also having a shank portion of soft skin with a foam plastic filler.
  • the shank portion allows the boot to be conveniently worn by the foot without the risk of galls even in the case of extensive ankle movements and when skiing.
  • a footwear such as a ski boot, having a toe portion and a heel portion and including an upper of cellular rubber and a sole of plastic material attached to the upper, the improvement, comprising:
