The invention relates to a frame for a sporting device for coupling to a shoe, such as a ski which is slidable or rollable by means of wheels, in particular a cross-country ski, or a skate frame for an ice-skate or roller-skate, which frame comprises: an upper sub-frame with means for coupling to a shoe to be worn by a user; a lower sub-frame which is coupled via a pivot mechanism to said upper sub-frame for pivoting in a main plane and which is provided with or adapted to be provided with a runner or wheels; and resetting spring means for urging both sub-frames toward each other. The frame according to the invention has the special feature that the sub-frames are mutually pivotable and translatable in the said main plane. A specific embodiment has the feature that the sub-frames form part of a mechanism comprising at least four mutually pivotable and/or translatable (optionally theoretical) rods.
