Abstract: The present invention is directed to a four-component releasable mounted cleat assembly for interlocking into a receptacle of an athletic shoe wherein an inner rotating component may reciprocally swivel within an outer stationary component. The outer stationary component having a plurality of rigid posts extending outward for firmly gripping turf. The inner rotating component has a plurality of resilient legs extending outward in a radial direction for rotatably gripping the turf, wherein each leg may swivel in clockwise and counter-clockwise directions about 15° in relationship to the outer stationary component. The cleat assembly has a locking component which is biasly rotated in a first direction to install it within the shoe receptacle, and a geometric construction of downwardly extending tongues causes a requirement for a greater torque remove the cleat than was necessary to install it.

Abstract: The present invention relates to a fluid filled apparatus that reacts with the stimulus of outside forces, furnished at the instep area of a shoe upper and the forefoot area of the shoe sole. The apparatus provides cushioning and a custom fit to the shoe in an area surrounding the forward portion of the shoe wearer's foot. In particular, the present invention pertains to a reactive energy apparatus comprised of anatomically shaped fluid filled bladders or pads that are furnished at the instep area of the shoe upper and the forefoot area of the shoe sole. The bladders engage and assume a complimentary custom fitting configuration around the instep and ball of the shoe wearer's foot by displacement of fluid contained in the bladders, and thereby provide cushioning and a custom fit around the shoe wearer's foot.
