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.

Footwear force mitigation assembly

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 structures disposed in the shoe sole. A footwear article includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation structure is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.
