Abstract
A glider device includes a pair of swingably mounted foot platforms pivotally supported by links at their heel ends. A spring cage, in one embodiment, includes a tension spring in each link to resiliently support the heel end of the foot platform. The spring cage limits displacement of the tension spring and includes a compression spring that cushions the displacement of the tension spring. In the a second, preferred embodiment, a stack of rubber bushings is supported in the spring cage and compress and decompress to provide a cushioning action to the foot platform.
