Estimating the term…
Athletic shoe sole with cleats having exchangeble grip elements that are snap-locked to a mounting stud. The grip element can easily be inserted and removed again, without impairment of shoe sole stability or danger of damage thereto, by the provision of interactive engagement formations, comprised of a minimum of one raised area 16, 17, 26 and a complementary recessed area 19, 28, that have at least one inclined surface that produces a relative axial shifting between the gripping element and mounting stud when the gripping element is rotated about its longitudinal axis. Preferably, the raised areas 16, 17, 26 are arranged such that, in the snap-locked condition, they do not have operative contact with the recessed areas 19, 28, but can be brought into operative contact by rotating grip element 11 around its longitudinal axis x, and thereafter the grip element 11 can be pressed out over the catch point of the snap-lock device or snap-lock devices 8, 12 to release the grip element from the mounting stud.
Athletic shoe sole having cleats with exchangeable grip elements of the type including mounting studs attached to the sole and a grip element, at least a part of which is made of elastic material that is securable over a respective mounting stud by way of a snap-lock arrangement comprised of at least one exterior surface formation of each stud that is interengageable with a complementary grip element inner wall surface formation, wherein the sole is provided with disengagement means, that is operative by rotation of at least part of the grip element about its longitudinal axis, for producing a longitudinal displacement of the grip element relative to its respective mounting stud sufficient to shift the surface formations past a catch point thereof so as to release said snap lock arrangement securing the grip element of the cleat from the mounting stud thereof.
