An article of footwear includes an upper and a sole structure with a sole member. The sole member can be manufactured using a system that modifies the forefoot cushioning of the sole member over a series of footwear purchases. The modifications can be configured to correspond to a customer's evaluation of the forefoot cushioning previously purchased. The sole member can include a set of apertures or incisions that are formed along various surfaces of the sole member to adjust the cushioning characteristics of the sole member.
