A method of forming a midsole includes the steps of placing a first mold member and a second mold member in contact with one another, injecting a first material into the first mold member to form first and second portions of a midsole preform, positioning the first and second portions in a third mold member of a second mold assembly; placing a second material in the third mold member; placing the third mold member and a fourth mold member in contact with one another, subjecting the second material and the first and second portions to heat to form a midsole preform, placing the midsole preform in a fifth mold member, placing the fifth mold member and a sixth mold member in contact with one another; and subjecting the midsole preform to heat and pressure to form a midsole.

Method of manufacturing sole assembly for article of footwear

An article of footwear with a heel cushioning system is disclosed. The heel cushioning system includes a sole, a curved plate and tread members. The tread members may lift a heel portion of a sole above a ground surface. The curved plate may deflect when a force is applied to the sole.

Article of footwear with heel cushioning system

Footwear sole structures include: (a) a chassis member including a lateral side, a rear heel portion, and a medial side, wherein the chassis member includes an opening defined between the medial side and the lateral side; (b) an impact-attenuating member engaged with the chassis member, wherein the impact-attenuating member includes a lateral side arm and a medial side arm that extend toward a forefoot portion of the sole structure, and wherein the impact-attenuating member further includes a rear heel portion joining the lateral and medial side arms; and (c) an outsole element extending beneath the impact-attenuating member, wherein the outsole element extends around the rear heel portion of the impact-attenuating member and engages the rear heel portion of the chassis member.
