A method for mass producing midsoles for articles of footwear includes the following steps: forming first midsole portions of an article of footwear in predetermined sizes with a hollow area for receiving an insert and an aperture in at least one side of the first midsole portion for viewing the insert; forming inserts in predetermined sizes and shapes for placement in the hollow area of the first midsole portions; matching the predetermined size of the inserts to one or more predetermined sizes of first midsole portions; forming the size and shape of the hollow area and aperture for a given size first midsole portion to accommodate the predetermined size and shape of the insert; placing inserts into the hollow area of size matched first midsole portions; adjusting the position of the at least one aperture gasket along the side of the mold to align with the aperture in the first midsole portion; inserting the aperture gasket into the aperture of the first midsole portion to completely seal the aperture; pouring an encasing material into the hollow area of the first midsole portion and around the insert; closing the mold around the hollow area of the first midsole portion; and allowing the encasing material to cure around the insert to secure the insert to the first midsole portion whereby the insert and encasing material form a second midsole portion.
