A footwear with a fluid which flows through integral chambers and passageways within the sole in which additional traction elements may be selectively and forcedly deployed and retracted. Valves on the footwear in combination with a control system, control the flow of the fluid allowing the user to choose between a range of traction deployment options to suit the needs of the user.

An actuation system including a gear assembly, a plurality of friction members, an outsole for an article of footwear and an actuator. The gear assembly having a plurality of gears and each friction member being coupled to a respective gear of the gear assembly and having a series of textured outer surfaces. The outsole having an inner portion, an outer surface, and a plurality of openings extending from the inner portion to the outer surface, each opening being configured to receive one or more friction members such that at least one textured outer surface of each friction member is exposed on the outer surface of the outsole. The actuator is configured to rotate one or more gears of the gear assembly such that each friction member rotates relative to the outsole.

A sports shoe, particularly for soccer use and the like, comprising an upper and a sole which is provided with one or more studs, each stud being associated with the sole by way of at least one elastically deformable element for the movement of at least part of the stud about its own longitudinal axis in such a manner as to follow the movements of change of direction, traction and stopping of the athlete who is wearing the sports shoe, the sports shoe further comprising a stripping prevention element that lies inside the sole and the stud, passing through the elastically deformable element in order to prevent accidental breakages of the elastically deformable element and/or the separation of the stud during the use of the sports shoe.

In an anti-slipping device for a shoe sole having an anti-slipping or anti-sliding component such as nails or spikes which are not secured to the sole but are secured on support elements which can be overturned to be hidden in slots made on the sole itself, each overturning support element is hinged at its ends on cubic blocks which are anchored to the sole due to a mushroom-shaped coupling element which is molded in once piece to the cubic block itself, made of the same thermo-polyurethane material as the support elements and which is snap-fitted in its seat arranged in the sole next to the slot where the overturning support element is accommodated after the overturning, without interfering with the integrity of the sole itself and thus allowing the replacement thereof without difficulty. Also included is a mechanism for avoiding the accidental loss of the support element when walking.

An outsole for a shoe includes i) a main tread to be secured to a shoe, the main tread having a sole portion and a heel portion, ii) at least one non-slip element integrated to the main tread and being positioned within one of the sole and heel portions; and iii) a retractable crampon, including at least one spike, that is mounted to the other one of the sole and heel portions of the main tread. The retractable crampon is movable between a deployed position, wherein the at least one spike extends from the main tread, and a retracted position, wherein the at least one spike is prevented from contacting the ground by the main tread.

The invention relates to a sole arrangement (10) for an anti-slid shoe (1). Said sole arrangement (10) comprises an upper and a lower sole member (20, 50) wherein the lower sole member (50) is vertically movable in relation to the upper sole member (20). Spike holding units (15) are arranged at the upper sole member (20) and are configured to hold spike members (8) extending in a vertical direction inside the sole arrangement (10). The sole arrangement (10) further comprises a locking system comprising spacing means (12) and a movable locking plate (30) arranged between the upper and lower sole members (20, 50), configured to control the vertical distance between the sole members (20, 50) to prevent the spike member (8) from protruding through the lower sole member (50). The spike holding unit (15) extends downwards through an opening (17) in the locking plate towards a spike opening (16) in the lower sole member (20).

A shoe with spikes is disclosed. The shoe includes an accommodation seat, at least one moving plate, a transmission module, a plurality of posts, a plurality of spikes, and a shoe plate. The accommodation seat includes a chamber. The moving plate is disposed in the chamber and controlled to move between a first position and a second position, and includes a plurality of push members. The transmission module is configured to move the moving plate. The posts extend from the accommodation seat toward the ground. The spikes are fixed to the posts and extend out of the chamber. When the moving plate is in the first position, the spikes protrude out of the shoe plate relative to the ground. When the moving plate is moved to the second position, the push members push the shoe plate, and the spikes do not protrude out of the shoe plate.

A non-slip arrangement for footwear, comprising a) a lower (1) and upper (2) layer, and at least one non-slip element, such as a stud (5), fastened in relation to the upper layer (2). The non-slip element is arranged in a non-slip device opening (7) formed in the lower layer (1) and extending through said lower layer (1). The arrangement further comprises a shift element (3), which is adapted between the upper and lower layers (1, 2) to be moved between said layers and, in relation to them, from a first position to a second position and vice versa. The shift element (3) comprises shapes which in its first position settle in said three-dimensional shapes of the upper and/or lower layer (1, 2). The shapes of the shift element (3) are arranged to move the upper layer (2) farther from the lower layer (1) in said second position, thus widening the distance between the layers (1, 2). In the first position, the tip (8) of said at least one non-slip element extends through the non-slip device opening (7) to the side of the bottom surface (9) of the lower layer, and in the second position, said tip (8) of the non-slip element remains in the non-slip device opening (7). Both the upper and lower layer (1, 2) comprise three-dimensional shapes on the surface adapted in the direction of the other layer, so that the protrusion-like shapes of the upper layer (2) are shaped to fit in the recess-like shapes of the lower layer (1).

In an anti-slipping device for a shoe sole having an anti-slipping or anti-sliding component such as nails or spikes which are not secured to the sole but are secured on support elements which can be overturned to be hidden in slots made on the sole itself, each overturning support element is hinged at its ends on cubic blocks which are anchored to the sole due to a mushroom-shaped coupling element which is molded in once piece to the cubic block itself, made of the same thermo-polyurethane material as the support elements and which is snap-fitted in its seat arranged in the sole next to the slot where the overturning support element is accommodated after the overturning, without interfering with the integrity of the sole itself and thus allowing the replacement thereof without difficulty. Also included is a mechanism for avoiding the accidental loss of the support element when walking.
