Regarding ski weighting with.

[Conventional technology]

As a ski boot equipped with a tightening adjustment device that can change the degree of tightening on the front and instep of a skier's foot, there is known a ski shoe disclosed in Japanese Patent Application Laid-open No. 8054/1983.

The ski shoe tightening adjustment device disclosed in the above-mentioned known technology includes:
A plate member formed of a relatively rigid material is arranged between the outer shell and the inner boot, which face the front and instep parts of the foot, and a plurality of tightening adjustment members provided on the outer shell are arranged on this plate member. The degree of tightness against the foot can be adjusted by connecting the adjustment member with the inner boot and moving the plate member toward or away from the inner boot by manually operating the adjustment member.

[Problem that the invention seeks to solve]

In the conventional ski boots as described above, the adjustment member is provided in a screwed structure on the front part and the instep part of the outer shell.
Although it is possible to directly adjust the tightness of the front and instep with the foot inserted into the shoe, in order to take the foot out of the shoe without much effort, the adjustment member must be loosened.
Moreover, after putting on the shoes again, the tightening force must be readjusted, which makes the operation complicated and troublesome.
The setting of the adjustment mechanism changes.

In addition, since the plate member only presses the front and instep of the foot from the top side, it is almost impossible to adjust the tightness on both sides of the foot, resulting in insufficient fit and hold of the foot within the shoe. Therefore, there was a problem in that the operability of the ski, such as edging operations, was deteriorated.

C. Purpose of the Invention The present invention has been made to solve the above-mentioned problems. To provide a ski shoe which can be simultaneously made possible with one touch without causing any discomfort, and which has good fitting and holding properties for the foot inside the shoe.

[Means for solving problems]
