Liner (10) for sports shoes, method of making liner adapt to feet and sports shoes

Abstract

The present invention refers to a liner (10) for sports shoes, a method of customizing the liner to make the liner adapt to feet of a user and sports shoes with the liner, the liner comprising a sole(11), an upper (12) to which is associable at least one deformable hollow insert (18), adapted to custom fit said liner (10) to a user's foot. Specifically, in said deformable hollow insert (18) a plastically deformable filler material is injectable at room temperature in a reversible manner by applying an injection pressure by means of a device (23). Moreover, said plastically deformable fillingmaterial is suitable to be suctioned, at room temperature, with said device (23) from said deformable hollow insert (18) applying a suction pressure.

Description

technical field [0001] The present invention relates to linings for sports shoes, preferably ski boots and the like. In particular, the present invention relates to an apparatus and method for adapting a liner to the morphology of a user's foot and lower leg based on the needs of the user. In other words, the liner can be customized according to the purpose of the shoe by adapting the liner to the preferences and movements of the user. Background technique [0002] A liner worn by a user is inserted inside a sports shoe such as, for example, a ski boot. These liners provide insulation, cushioning and comfort during use and are usually made of multiple sections of different shapes and materials that are glued or sewn together. [0003] Liners are typically produced in different sizes, each of which has a predetermined size; however, users of the same size may have different foot shapes. Also, there may be asymmetry between the feet of the same user. [0004] For this reas...

Problems solved by technology

This solution has the advantage of not generating heat during the crosslinking; however, as in the previous case, it has the disadvantage that a relatively long waiting time is required to ensure complete crosslinking of the compound, so if the foot moves during the process , you may get an incorrect fit

It's actually very easy to make mistakes at this stage and cause damage beyond repair as the process is usually irreversible

[0016] Furthermore, the customization is usually carried out under environmental conditions different from those used in sports shoes and in which the lining is incorporated, so there is a risk that the results obtained when customizing the fitting procedure do not correspond to those used in practice by the user. Exercise requirements

[0017] Finally, it is not possible to carry out a subsequent custom fit or optimization of the lining after, for example, changes in the morphology of the foot over time or subsequent adjustments to the sneaker, possibly necessitating a complete replacement of the lining or lining
