Definitions

  • the present invention relates to a sports shoe, in particular skiing or skating, comprising a hull made of plastic and an inner liner, said shell having at least one zone of rigidity less than the rigidity of the rest of the hull.
  • the present invention aims to provide a simple solution to the problem of pain felt in level of the metatarsophalangeal joint.
  • the width of the metatarsophalangeal joint varies as well as its position relative to the heel.
  • the shoe according to the invention is characterized in that that the lower stiffness zone is an area relatively flexible located on the side of the hull corresponding to the exterior and / or interior side of the foot, so as to be in front of the joint metatarsophalangeal.
  • This area may be reduced in size, but its flexibility must be sufficient for it to easily deform laterally under the pressure of the metatarsophalangeal joint without exerting a painful pressure on this area.
  • This lower stiffness zone is preferably obtained by injection, according to a bi-injection process, flexible plastic in said area.
  • the shell can of course have other areas of less rigidity.
  • FIG. 1 represents a ski boot, seen from the outside of the foot.
  • Figure 2 is a cross-sectional view along II-II in Figure 1, without the closure loop and Tightening.
  • Figure 3 is a cross-sectional view along II-II in Figure 1, without the closure loop and tightening representing a second embodiment of the invention.
  • the ski boot shown in Figure 1 is consisting of a shell 1, called a variable volume, intended to surround the foot and ankle and with a collar 2 articulated on the shell 1 at a point 3 located in the malleolar region, this collar 2 being intended to surround the lower leg.
  • This shoe according to a well-known construction, has two loops clamp 4 and 5 for clamping the shell 1 and two loops 6 and 7 for tightening the collar 2.
  • an inner comfort shoe 8 8
  • the shell 1 is consisting of two layers of plastic la and 1b associated by a bi-injection process, or multi-injection or by bonding or by another equivalent process.
  • the plastics used are preferably polyurethane.
  • the layer there, located inside the hull consists of a plastic with substantially elasticity greater than the elasticity of the outer part 1b which includes the sole 9 and the upper flap 10 of the shell which is made only of the most plastic rigid.
  • the part outer 1b of the shell has a cutout 11 positioned to surround an area of the hull located in front of the metatarsophalangeal joint of the foot.
  • This cut 11 delimits an area 12 in which one encounters only the least plastic rigid the.
  • the flexibility of the plastic is such that zone 12 can deform slightly under pressure of the metatarsophalangeal joint of the foot of so as to significantly reduce the pressure on this joint and, therefore, to avoid the appearance of pain there.
  • Layer 1b plastic has hardness between 58 and 68 shD for example 62 shD, while that the layer has a hardness of between 45 shD and 55 shD for example 54 shD.
  • zone 12 may vary within a certain extent, this extent should not however be too great not to affect the general stiffness of the front end of the hull.
  • the shell 1 consists of a single layer of material plastic and it has a cutout 11 similar to that of the first embodiment described above.
  • This cutout delimits an area in which meets a plastic element 13 less rigid than the rest of the hull, said element 13 being fixed to the comfort liner 8 itself and not the shell 1, as in the first embodiment.
  • the flexibility of this less rigid plastic element 13 allows also a slight deformation under the pressure of the metatarsophalangeal joint.
  • the tightness of the shell 1 is ensured during tightening of the shoe on the foot.
  • the flexible material could only be provided in the area 12.
  • the flexible material could be in the continuation of the rigid material, even to outside of it.
  • the element 13 made of less rigid plastic can surround, at least partially, the inner liner 8.
