Abstract
A footwear sole structure for dynamically directing interacting forces between a user's foot and the footwear during a stride, including an inner sole located adjacent the user's foot, a mid-sole located between the inner sole and the footwear, and a rib ribbon force transfer structure located between the inner sole and the mid-sole wherein the rib ribbon includes a plurality of ribs spaced along and transversely to a spine axis and attached to a longitudinally extending spine. The rib ribbon resists flexing about an axis parallel to the spine axis and allows a relatively greater degree of flexing about an axis transverse to the spine axis and the rib ribbon is located along a path between the inner and mid-soles to dynamically direct the interacting forces between a user's foot and the footwear as the user's weight shifts from a heel to a toe position during a stride.
