Abstract
The present invention relates to a shoe sole having a resilient insert which provides fluidic cushioning and support to the foot of the wearer. The resilient insert has a heel chamber, a forefoot chamber and a passageway, which fluidly connects the heel chamber to the forefoot chamber. As the wearer walks or run and applies impact forces to the shoe sole, fluid within the resilient insert flows back and forth between the heel chamber and the forefoot chamber to provide continuous cushioning and support to the heel and fore portion of the wearer's foot. The resilient insert and components of the sole are specifically constructed and assembled to avoid friction and turbulence therein, which can result in the production of audible and undesirable noises within the interior of the shoe sole.
