Abstract: A mold used to form a midsole for an article of footwear and a method of manufacturing are disclosed. The mold includes a first portion and a second portion cooperating to define a midsole recess, the first portion including a major recess and plurality of wall segments extending throughout the major recess and cooperating to define a plurality of minor recesses. A fillet is provided at each intersection of adjacent wall segments. The mold may have a draft angle of less than or equal to approximately 2.5 degrees.

Abstract: A method of manufacturing a midsole includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

Abstract: A composite panel portion of an upper may include a contouring element located between a backing and an outer panel. The outer panel conforms to the contouring element and the backing so as to form a raised contour.
