Non-slip arrangement for footwear

A non-slip arrangement for footwear, comprising

• a) a lower (1) and upper (2) layer adapted at least partly overlapping,
• b) at least one of said upper and lower layers (1, 2) comprises, on the surface adapted in the direction of the other layer, three-dimensional shapes such as recess-like and/or protrusion-like shapes,
• c) at least one non-slip element, such as a stud (5), fastened in relation to the upper layer (2),
• d) which 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),
• e) 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,
• f) which 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), and
• g) which 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),
• h) whereby 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
• i) in the second position, said tip (8) of the non-slip element remains in the non-slip device opening (7), characterised in that 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).
