<p>The present invention relates to a joint-sparing shoe, mainly for sport or orthopedic use, the shoe comprising a shoe upper (2) and a shoe sole (3) connected fixedly to the shoe upper (2), wherein at least in the front part of the shoe a region is formed, in which a lower sole layer (5) of the shoe sole is adapted to rotate along a circle in a guided manner in response to a torsion load, and then to return to its initial position relatively to an adjacent sole layer (4), wherein the sole layers (4, 5) are connected to each other by means of at least one binding element providing a stable connection thereof while, at the same time permitting their rotation with respect to each other. According to the invention, the sole layers (4, 5) which are capable of rotating with respect to each other in a guided manner, but can rotate only when the torsion load reaches a critical value, at which the knee ligaments are jeopardized, are provided with and fitted with a plurality of concentrically alligned ached ribs (7, 7') and circular grooves (8, 8'), wherein the gap between said two sole layers (4, 5) are filled with an elastically deformable adhesive material (9), and wherein for the stable connection of the sole layers (4, 5), for their limited rotation with respect to each other and for their return to their initial positions, binding studs (6) made of a rubber-like elastic material are provided as binding elements, said binding studs being fixedly and/or integrally connected to both sole layers (4, 5) and arranged equidistantly in one or more circular grooves (8, 8'). The shoe of the present invention can preferably be used in sports where it is important to ensure the possibility of turning of the front part of the sole, but its orthopedic application can also be useful e.g. for the rehabilitation of patients after surgical operation of their knee joints.</p> |
