Definitions

  • the toe and heel parts of the sole are adequately hard to take up the pressure to which they are subjected by the ski binding, while the ski boot as a whole does not unduly restrain the rolling motion of the foot on the ski.
  • the present invention relates to a ski boot with an outer sole of rubber or plastic which is cast upon the upper and preferably directly upon the same.
  • the outer sole of the known ski boots has a relatively high Shore hardness which usually amounts to more than 85. This was regarded as necessary in order to insure that the sole would take up the pressure to which the toe and heel parts of the sole are subjected by the ski binding.
  • the area of the sole of the ski boot which is affected by the rolling motion of the foot is therefore made of such a softness, for example, of about 70 Shore, that it will permit the foot to carry out such a rolling motion along the ski without any restraint, and this soft area is designed so as not to affect the pressure resistance of the sole at the toe and heel areas thereof.
  • the area of the outer sole which according to the invention is made of a softer degree is generally made of a length of 8 to 10 cm., as seen in the longitudinal direction of the sole.
  • a multistage injection method for example, one consisting of two stages, in which the areas which are to be filled out in the mold during the first injection stage are blocked off from the area which is to be filled out during the second injection stage.
  • the accompanying drawing illustrates a ski boot with a cast-on outer sole in which the different areas of this sole as previously described should have diiferent degrees of Shore hardness.
  • the outer sole 2 of rubber or plastic is cast upon the upper 1 of a ski boot and is provided at the toe and heel areas with projecting bulges 3 which are drawn upwardly for a certain distance along the outer side of the upper.
  • the softer part of the outer sole, shown at S lies within the area of the rolling motion of the foot, there being harder parts H ahead of and behind this softer part. While, as aforesaid, the softer part of the sole will have a Shore hardness of about 70, this value may, in practice, lie within the range of about 65 and Shore, while the harder parts of the sole will be at least about Shore and may, in practice lie within the range of about 88-95 Shore. These numerical values, it will be understood are not strictly limitative but serve to exemplify the considerably lower Shore hardness of the ball part as compared to the Shore hardness of the remainder of the sole, as stated throughout the instant specification and claims.
  • a ski boo-t having an upper and an outer sole made of rubber or plastic and cast on said upper, said sole having a ball part which is spaced from the front and rear of the boot and front and rear parts constituting the remainder of said sole, said ball part being d sposed below the region to be occupied by the ball of the wearers foot and having a Shore hardness of between about 65 and 75 and the remainder of said sole having a Shore hardness of at least about 85.
