Abstract:
1. A method of forming a midsole with a first mold assembly having a first mold member and a second mold member with a first recess formed in the first mold member, and a second mold assembly having a third mold member and a fourth mold member with a second recess formed in the third mold member, comprising the steps of: placing the first mold member and the second mold member in contact with one another; injecting a first material into the first recess in the first mold member to partially cure and form a first portion of a midsole while the first mold member is maintained at a temperature below an ambient temperature; removing the first portion of the midsole from the first recess; positioning a second material and the first portion of the midsole in contact with one another in the second recess in the third mold member of the second mold assembly; placing the third mold member and the fourth mold member in contact with one another; and subjecting the second material and the first portion in the second mold assembly to heat and pressure such that the first material completely cures and the first portion and the second material bond to form a midsole.
