1. An impact absorbing footwear device, comprising:
a lower plane defining a frictional interface to a floor surface;
an upper plane configured to laterally engage the lower plane, the upper plane aligned with the lower plane for coordinated movement, the upper plane defining an interface to a wearer of the footwear appliance; and
at least one impact absorbing structure for absorbing forces between the upper and lower planes in response to the coordinated movement;
the impact absorbing structures including an elongated resilient member extending between a plurality of uprights extending orthogonally between the upper and lower planes, the elongated resilient member disposed for deflecting in response to an opposing lateral force between the upper and lower planes.
