AI Technical Summary

Benefits of technology

[0027]As resulting advantage, it is much easier to put on and remove the boot, because there is increased space for passage of the foot.
[0028]Generally speaking, the boot according to the invention offers greater comfort, whether in static mode or in dynamic mode, i.e., whether the wearer is in motion or not.

Problems solved by technology

Consequently, one's performance, especially in sports, is adversely affected.
Moreover, repeated foot movements in the upper can translate into friction that causes injuries to the foot.
However, known boots have been found to provide incomplete foot support.
In addition, putting on or removing such boots is not always easy.

first embodiment

[0037]The first embodiment described hereinafter relates more particularly to boots intended for the practice of cross-country skiing or telemark skiing. However, the invention applies to other fields, such as those mentioned above.

[0038]A first embodiment is described hereinafter with reference to FIGS. 1 to 6.

[0039]As shown in FIG. 1, a cross-country ski boot is provided to receive the user's foot.

[0040]As known, the boot 1 includes an upper 3 and an exterior sole 2, i.e., a walking sole. The boot 1 extends lengthwise from a rear end 4, or heel, to a front end 5, or tip, and width-wise between a lateral side 6 and a medial side 7.

[0041]As shown, the upper 3 includes a lower portion 10, provided to surround the foot, as well as a top portion 11, provided to surround the ankle. However, an upper could be envisioned to have only a lower portion, i.e., the boot thereby having a low upper.

[0042]According to the first embodiment being described, the boot 1 extends height-wise from the b...

second embodiment

[0081]The boot 1 is not provided with a flap, a blocking device, or connection(s) for fastening the boot to a binding. This boot is adapted, for example, for walking, or for operating a snowshoe.

[0082]For example, the boot 1 includes an additional connection or guide 80 for the second linkage 32. This guide is located on the upper 3, on the lateral side 6, plumb with the upper subdivision 18 of the opening 17. The guide 80 maintains the linkage 32 on its nominal trajectory.

[0083]The invention is embodied from materials and according to implementation techniques known to one of ordinary skill in the art.

[0084]The invention is not limited to the particular embodiments illustrated and described hereinabove, and encompasses all of the technical equivalents that fall within the scope of the claims that follow.

[0085]In particular, in any case, the structure of a tightening device can be inverted, in the sense that the specific characteristics associated with a medial side can be applied ...

Abstract

A boot including a sole and an upper, the boot extending length-wise from a heel to a front end, and height-wise from the sole to an upper end, the boot having an opening for foot insertion, and including a lateral portion, a medial portion, as well as a tightening device, the tightening device including a first linkage, a second linkage, as well as connections of the linkages to the upper. The first linkage runs from one portion to the other, in the area of the instep. The second linkage passes through an initial sliding connection located on one of the portions, then through a first intermediate sliding connection located on the other portion, then extends along the upper by going around the heel, between the sole and the upper end, so as to arrive at a fixed end connection located on that of the portions which carries the initial connection.
