Abstract:
A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation assemblies disposed in the shoe sole. A force mitigation assembly adapted for an athletic shoe includes a linkage to a wearer interface responsive to movement based on activity of the wearer. An attachment to a sole surface receives ground forces transmitted from frictional contact between the sole surface and a surface against which the sole is disposed, such as for running, turning, etc. A force mitigation assembly absorbs these forces received from the sole surface for directing the received force in a controlled manner. An elastic field in the force mitigation assembly is defined by a resilient material adapted to deform in response to the received force.
