A hopping and dancing shoe comprises a sole member, a base member parallel thereto, and a spring therebetween. Two means are provided by the spring to resist yawing of the sole member relative to the base member: (1) the spring has an axial extension of each end which is connected to the sole member and base member, respectively; and (2) the extreme outer coils of the spring are in contact with the sole member and base member, respectively, to provide frictional contact there between.

A shoe containing a cushioned sole assembly includes in one embodiment a spring cushion feature inserted between two flexible hinged sole segments and in a second embodiment a spring cushion fastened to an adjustable hinged spring mounting plate. The cushion assembly can be a part of the shoe manufacture or the assembly can be a separate unit fastened and adjusted to the sole of a shoe by clamp brackets. The sole cushioning assembly can be adapted for any tipe of shoe including jogging and other athletic shoes, protecting the feet of joggers and others from injuries that occur during use on hard surfaces, shoes for workers, providing comfort for those who must stand on hard surfaces for many hours during a day and insulating the feet of the user from surfaces that have extreme hot or cold temperatures.

An exercise shoe includes a shoe body and a frame fastened to the underside of an outsole of the shoe body. The frame is provided therein with a circular body in which a spring is located such that both ends of the spring are engaged with the retaining rings of two control rod members, and that the spring can be expanded or compressed by the control rod members so as to adjust the resilience of the frame. The frame is provided with a skidproof bottom to prevent the exercise shoe from skidding on a surface.

Front and rear springboard assemblies having telescoping members biased apart by springs are provided for atachment at front and rear positions to a skateboard-like deck to provide a springboard device which can be moved foward along a path by successive leaps and bounds. In one embodiment, the assemblies are configured as attachments to be mounted on a conventional skateboard in place of wheeled trucks. In another embodiment, the assemblies are configured to serve as spring-loaded mounts onto which wheeled trucks are attached.
