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.
