Abstract
Footwear construction having a comfort cradle device disposed in a midsole socket for support above the outsole contact with a walking or running surface and in which the cradle device is shaped to afford self centering and position stability for the wearer's foot. The cradle device is interlocked with the midsole through a system of fingers that move in response to the shift in applied load to return energy to the cradle.
