  • FIGS. 18, 24, 25, 26, 14 and 15 differ from FIGS. 18, 24, 25, 26, 14 and 15 in that the sole 25 is designed with the elastic bending zone 26 instead of the pivot bearing 7 . It is also possible to provide the elastic bending zone 26 of the sole 25 in addition to the pivot bearing 7 .
  • the front cap 1 is flexibly, ie elastically bendable, connected to the main shell 2 in the toe base joint area 20 via the bending zone 26 .
  • the movable front cap 1 allows the sole of the foot to roll over the bending zone 26, as shown in FIGS. 37 and 39, for example.
  • the shell shoe can be fixed in a defined stretched position. In this stretched position, the front cap 1 is connected to the main shell 2 via a locking device 16 (FIGS. 16, 17) or via a cable pull (not shown) in such a way that it functions statically as a closed shell.

  • a larger lever for clamping can be achieved (distance from the pivot bearing 7 or from the bending zone 26 is larger), whereby the clamping force for fixing the front cap 1 increases.
  • the shell shoe according to the invention therefore has an additional bending zone 26 in the area of the sole 25 in the area of the metatarsophalangeal joint 20, which means that when it is designed as a touring ski boot, it is possible to roll first over the bending zone 26 and then over the third axis of rotation Z - is made possible.
  • 37 and 38 show this additional rotational movement over the bending zone 26 and only then over the third axis of rotation Z, similar to FIGS. 4 and 5. This enables a significantly more favorable rolling geometry and thus an ergonomic gait.
  • the rotatable front cap 1 in the shell shoe designed as a touring ski enables improved mobility between the ski and shoe in the ascent mode through rotary movements around the bending zone 26 and the axes of rotation Y, Z, resulting in an ergonomic rolling movement of the foot on the ascent can take place with skis.

Abstract

L'invention concerne une chaussure rigide, en particulier pour le ski, la chaussure rigide comprenant une région d'articulation métatarsophalangienne (20), une région de cou-de-pied (21), une région métatarsienne (22), une région de talon (23) et une région d'articulation de la cheville (24), la chaussure rigide comprenant également un bout dur avant (1) dans la région d'articulation métatarsophalangienne (20), ce bout dur avant étant relié de façon mobile à la coque principale (2), et une tige (3) et une coque principale (2) de la chaussure rigide étant interconnectées dans la région d'articulation de la cheville (24) de manière à pouvoir tourner autour d'un second axe de rotation (Y). Afin d'améliorer la rigidité et la stabilité en torsion, la chaussure dure comprend un dispositif de stabilisation (30) par l'intermédiaire duquel le bout dur avant (1) est stabilisé vis-à-vis de la torsion par rapport à la coque principale (2).
