Abstract

The present invention relates to flexible footwear that comprises flexing means, either in the sole or in the upper, or in both, and said means in turn comprise a groove placed transversely and recovering means placed transversely to said groove such that, when the footwear flexes along the groove, the action of said recovery means cause the footwear to recover, promoting recovery of the initial form of the footwear upon completion of each step, and thereby enhancing walking comfort.

Claims (13)

1. Flexible footwear characterised in that it comprises flexion means (1) that in turn comprise at least one groove (1.1) placed transversely in the anterior part of said footwear and recovery means (1.2) placed transversely to said groove (1.1), such that when the footwear flexes along the groove (1.1) it is recovered by the action of said recovery means (1.2), which are longitudinal configurations that in their ends extend beyond the width of the groove (1.1), these ends being placed in incisions (1.3) of the groove (1.1).
2. Flexible footwear according to claim 1, characterised in that the recovery means (1.2) are placed perpendicular to the tangent to the groove (1.1).
3. Flexible footwear according to claim 1, characterised in that the recovery means (1.2) are placed forming a broken line along the groove (1.1).
4. Flexible footwear according to claim 1, characterised in that the recovery means (1.2) are placed in two's, forming crosses along the groove (1.1).
5. Flexible footwear according to claim 1, characterised in that the flexion means (1.2) are placed in the sole (2) of the footwear.
6. Flexible footwear according to claim 5, characterised in that the flexion means are formed integrally with the sole (2) of the footwear.
7. Flexible footwear according to claim 5, characterised in that the flexion means (1.2) are formed separately to the sole (2) of the footwear and are joined to it by gluing or sewing.
8. Flexible footwear according to claim 1, characterised in that the flexion means (1.2) are placed in the upper (3) of the footwear.
9. Flexible footwear according to claim 1, characterised in that the groove (1.1) of the flexion means has a concave curvature with respect to the front end of the footwear.
10. Flexible footwear according to claim 1, characterised in that the groove (1.1) of the flexion means has a convex curvature with respect to the front end of the footwear.
11. Flexible footwear according to claim 1, characterised in that the groove (1.1) of the flexion means is straight.
12. Flexible footwear according to claim 1, characterised in that there are at least some flexion means in the anterior part (4) of the footwear and/or at least other flexion means in the mid area (5) of the footwear, coinciding with the two flexion areas of the foot.
13. Flexible footwear according to previous claims, characterised in that the flexion means of the upper (3) and of the sole (2) coincide in the same transverse section of said footwear so that the flexion and its recovery take place at the same time in the flexion means of the upper (3) and of the sole (2).
