1. A frame for a clap skate, which frame comprises: a lower frame part for carrying a runner or wheels; an upper frame part with means for coupling to a sole and a heel of a skate shoe; a hinge which couples the lower frame part and the upper frame part hingedly to each other, which hinge is situated at a distance above a foremost zone of the lower frame part and defines a first free degree of freedom of rotation in a main plane, or a plane varying a maximum of about 30° therefrom, of the runner or the wheels; and a resetting means for urging the upper frame part relative to the lower frame part to a rest position determined by a positioning means, in which rest position the lower frame part and the upper frame part have a smallest possible mutual distance; wherein the hinge comprises a ball joint, and wherein the hinge defines a second free degree of freedom of rotation within a range of ±30° perpendicularly of the first free degree of freedom, such that the upper frame part can perform an upward and downward as well as a lateral pivoting movement relative to the lower frame part.
