Abstract
A footwear sole comprises a foot-shaped sole of a relatively cushioned, low density polymer foam, with a higher density, harder midfoot shank portion integrally fused within it. The sole may be a unitary footwear sole or may have an outsole or insole adhered thereto. A method of manufacture of the sole comprises forming a polymer foam sole piece, stamping out a portion of the midfoot, forming a shank of higher hardness polymer foam to fit the stamped-out midfoot portion of the sole piece, fitting the shank into the sole piece, and hot compression molding the sole piece and shank to form a unitary, integral sole. The sole of the invention is particularly useful as a sandal sole.
