Abstract
Description
- The present invention relates to a sports shoe, in particular for trekking or hiking, and relative manufacturing method.
- The increased performance required in sporting activities, in particular for trekking and hiking in low, medium and high altitudes, requires an improvement in the movement of the ankle, especially in the descent phase, without thereby altering the characteristics of stability and security offered by boots.
- To obtain this increase in the antero-posterior movement of the leg with respect to the foot some variants of the collar have been developed in the prior art, i.e. the upper part of the shoe upper which surrounds the ankle area of the user and which delimits the access opening of the user's foot inside the shoe.
- A particularly critical portion of the collar is the rear portion which interfaces with the user's Achilles tendon.
- Indeed, said rear portion must allow a wide range of movement of the ankle, so that in descent the leg can move as freely as possible at the rear. At the same time the aforesaid collar needs to lock and support the leg with respect to the movements on the frontal anatomic plane; this function is very delicate in that the collar must also avoid creating pressure points all over the area of the leg in question which would make the shoe very uncomfortable and tiring to use. The collar must also laterally support the malleolus-tibial portion of the foot, maintaining rigidity and torsion.
- The solutions of the prior art are aimed at increasing the deformability of the rear part of the collar through the creation of facilitated deformation zones, i.e. more easily deformable portions in order to accommodate the anteroposterior rotational movement of the foot.
- Said portions are obtained for example by means of preformed dies with localised, high frequency welding to reduce the resistant cross-section of the collar, localised weakening of the fabric/material which form lines of weakening and thus of preferential deformation of said collar.
- It is also known of, for example, to make collars provided with gusset inserts which allow a greater elastic deformability thanks to the extensibility/compressibility of such gussets.
- These solutions are however not optimal for achieving the right balance of comfort and leg support.
- In fact, the weakening portions constitute pressure points for the user's ankle; moreover where there are no pressure points, the known solutions do not guarantee the necessary rigidity and therefore support to the ankle and to the user's leg.
- As a result the solutions of the prior art are focused on obtaining preferential elastic deformation zones which, however, constitute a compromise, often not very effective, between the comfort of the user and the foot support function.
- The purpose of the present invention is to overcome the drawbacks and limitations mentioned with reference to the prior art.
- Such drawbacks and limitations are resolved by a sports shoe according to claim 1 and by a manufacturing method of a sports shoe according to claim 13.
- Other embodiments of the shoe according to the invention are described in the subsequent claims.

- In particular, said method of manufacture of a
sports shoe 4, in particular for trekking or hiking, comprises the steps of: - - preparing an upper 8 that delimits, at least partially, a
housing space 10 of a foot of a user, the upper 8 being provided with an upper portion suitable to embrace an area of the foot near the malleolus-tibial portion, - - preparing a

- As may be appreciated from the description, the sports shoe according to the invention makes it possible to overcome the drawbacks of the prior art.
- In particular, the present invention does not set out to create solutions in which the collar has weakened portions with facilitated deformation which would not provide the best performance in terms of comfort or in terms of support to the foot.
- Instead, the present invention solves the technical problem by providing a collar having a preformed portion, i.e. arched, as a function of the natural anatomy of the rear portion of the foot, in correspondence with the Achilles tendon.
- Thanks to the fact that this portion is preformed with respect to the anatomy of the foot, first of all correct support is given to the foot. In addition, this configuration improves the comfort of the shoe because it befits the natural rotation-posterior tibial malleolus. At the same time, it also ensures the elastic effect accompanying the anterior-posterior rotation of the foot: in fact, during the anterior rotation the portion of the Achilles tendon is detached from the rear portion of the collar, while during the posterior rotation there is a direct contact between the portion of the Achilles tendon and the rear portion of the collar. The rear portion of the collar is already crimped according to a generic anatomical curvature of the foot and thus presents a good yielding and propensity to bend further back, naturally accommodating the posterior rotation of the foot. During the subsequent forward rotation said collar naturally tends to return to its rest configuration, and therefore to rotate forward again, again newly accommodating and supporting the Achilles tendon area. In fact, thanks to the fact that the collar is preformed according to the natural curvature of the Achilles tendon, the collar is no longer a passive element limited to yielding elastically under the thrust action of the foot, as occurs in the solutions of the prior art which provide predefined weakening lines.
- Instead, the collar of the present invention is an active support element that yields elastically under the thrust of the leg in its rotation backwards and, at the same time, anatomically supports the leg in its forward rotation.
- Moreover, no pressure points are created drastically reducing the comfort of the shoe.
- Moreover, thanks to the at least partial overlap of the edges of the collar it is possible to obtain collars having a much more accentuated curvature or thrust compared to the solutions of the prior art. This way it is possible to reproduce more faithfully the actual anatomy of the Achilles tendon, not otherwise obtainable with the known high-frequency welds of the prior art: obviously considerably increasing the comfort.
- Furthermore, as seen, the collar preferably has a "W" shape in the upper area, from the rear side, so as to ensure a constant pressure on the upper part of the leg in question by the upper portion of the boot. This shape makes it possible to obtain a constant mean lateral containment, without having an increase in pressure on malleoli and lateral/medial parts of the leg upon reaching maximum plantar flexing of the ankle.
- This way a further improvement of the comfort of the footwear is achieved without sacrificing the support function of the foot and ankle by said footwear.
- A person skilled in the art may make numerous modifications and variations to the solutions described above so as to satisfy contingent and specific requirements while remaining within the sphere of protection of the invention as defined by the following claims.
