Abstract
A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.
