Abstract:
1. Footwear comprising: a main shoe body provided with a recess on a bottom thereof; an upper body fixed to the recess and having a first plurality of magnets arranged at intervals in a circumferential direction; a lower body having a second plurality of magnets arranged at intervals in a circumferential direction, and rotatably connected with the upper body, such that the lower body is rotatable relative to the upper body while the lower body maintains a connection with the upper body, wherein said connection prevents vertical displacement between the upper body and the lower body; and rollers mounted to the lower body, wherein the first plurality of magnets of the upper body and the second plurality of magnets of the lower body are arranged so as to rotate the lower body to an initial position in which the second plurality of magnets are magnetically connected with the first plurality of magnets, from a different position in which the lower body is rotated from the initial position, by magnetism acting between the first plurality of magnets of the upper body and the second plurality of magnets of the lower body.
