The invention relates to a sole for footwear having a structure for minimizing injury to the wearer from twisting or turning movements which may occur during sporting activities, and/or for enhancing performance by assisting rotational movement of the foot. A first invention is a shoe sole comprises a turntable within the sole and connected thereto by a resilient web which provides a seal between the periphery of the turntable and sole. The web is resiliently deformable in response to rotation of the turntable in either direction from a rest position to apply resilient bias to restore the turntable towards it rest position. There may be additional biasing means. There are ten further disclosures of the turntable involving: using glue to fix the turntable and to provide the seal and resilient bias; a separate turntable having a wiper seal with the sole and additional biasing means; means for limiting the extent of the rotational movement; coil and leaf springs and interengaging portions of the sole and turntable to provide the resilient bias; a circular race of ball bearings to support the turntable; multiple turntables; means for fixing cleats or studs to the turntable. A second invention is a sole having annular rows of deformable fins which permit limited rotation of the sole.

[ What is claimed is:] [1.] A sole for footwear, the sole having a recess in which is mounted a turntable for rotation in opposing directions of rotation from a rest position, said turntable having an outer periphery separated from the sole by an annular space, and a resiliently deformable sealing structure of annular form extending around said outer periphery of the turntable and closing said space against ingress of dirt and mud, said resiliently deformable structure being attached to the sole and to the periphery of the turntable such that rotation of the turntable relative to the sole results in resilient deformation of the sealing structure, said deformation applying a resilient bias to the turntable acting in a direction to return the turntable to said rest position after rotation.
