Abstract
A method of manufacturing a midsole for an article of footwear includes placing first and second preforms in a first mold, closing and heating the first mold to produce a midsole preform with a peripheral preform flange, removing the midsole preform from the first mold and allowing it to further expand and cool, placing the midsole preform in a second mold, with a volume of a midsole recess of the second mold being less than a volume of the midsole preform, and a volume of a peripheral recess of the second mold being less than a volume of the peripheral preform flange, closing the second mold thereby compressing the midsole preform and the peripheral preform flange, and heating the second mold to form a midsole with a peripheral flange, allowing the second mold to cool, opening the second mold, and cutting away a peripheral flange of the midsole.
