ABSTRACT:
A spring shoe is provided, of the type which includes a top plate that holds a person's foot and a bottom plate coupled to the top plate through springs to allow for vigorous jumping, wherein the top plate is stabilized against unwanted motion in a simple and rugged mechanism. An elongated cross bar is provided which has a front end hinged to the front of the top plate and a rear end hinged to the rear of the bottom plate. The cross bar permits vertical motion and pitch of the top plate with respect to the bottom plate, while avoiding other unwanted motions of the top plate such as longitudinal and lateral shifting and tilting in roll.
