Cushioning system for footwear and related method of manufacture

摘要

A footwear cushioning system including an insole platform and an insert that cooperate with one another. The insole platform includes a recess defined in the heel and/or forefoot area. The insert includes a footbed and heel and/or forefoot cushion extending from the footbed. The cushions interfit with the respective heel and/or forefoot recess of the insole platform. In a preferred embodiment, the insole platform includes a shank secured thereto, surrounding the heel recess. The insole platform is preferably shaped to define both heel and forefoot recesses and the insert includes cushions that interfit with both recesses. A midsole is secured to the insole platform and an outsole is further secured to the midsole. To assemble the cushion system, the insole platform is secured to the upper. The midsole is then secured to the insole platform. The outsole is adhered to the under surface of the midsole. The insert is fitted into the upper over the insole platform so that the heel and/or sole cushions rest within the corresponding heel and/or sole recesses of the insole platform.
