The support plate (2) is rotatably attachable to the shoe heel with its rotation axis located in a plane close to that of the heel wear surface. The plate can be rotated at least through 180 deg. It moves from a first position, in which its one wholly smooth side surface coincides with the wear surface of the heel, to one in which its side (4) in which the studs (5) are fixed, coincides with the heel wear surface. |
