Abstract
A support and cushioning system for an article of footwear. The system includes a resilient insert disposed between a midsole and an outsole of a shoe. The resilient insert includes several chambers disposed in a heel portion of the resilient insert. These chambers are fluidly interconnected to each other via heel chamber interconnection passages. The resilient insert also includes several chambers disposed in a forefoot portion of the resilient insert. These chambers are also fluidly interconnected to each other. A connecting passage connects at least one of the chambers in the heel portion and at least one of the chambers in the forefoot portion of the resilient insert. A bladder having a fluidly interconnected heel chamber and forefoot chamber is also inserted above the midsole to provided added cushioning to the wearer. In one embodiment, the resilient insert contains air at ambient pressure and the bladder contains air at slightly above ambient pressure.
