Abstract
A footwear construction includes a sole assembly including a first midsole, a second midsole, a spring plate between the first and second midsoles, and an outsole. The plate can include an upward curving, multi-radii transition portion extending from a lowermost portion to a forward most portion of the plate so as to roll a wearer's foot forward into a next stride in a gait cycle of the wearer. The plate can include a lateral arm and a medial arm in the forefoot region separated by a plate slot extending rearward from the forwardmost portion of the plate toward the lowermost portion. The medial arm can be longer than the lateral arm. The plate can have a first bending stiffness during bending in a first direction, and a second bending stiffness greater than the first bending stiffness during bending in a second direction.
