FOOTWEAR WITH BLADDER FILTER

摘要

An article of athletic footwear (100) having an air-filled bladder (190) disposed in a sole structure (120) is disclosed. The air-filled bladder is in fluid communication with ambient air through a filter (130) that permits ambient air to enter the bladder but restricts liquids and particulates from entering the bladder. In operation, the filter and bladder may be portions of a bladder system that absorb shock when the footwear contacts a playing surface. Alternatively, the filter and bladder may be portions of a bladder system that ventilates the interior of the footwear. The filter may be formed of expanded polytetrafluoroethylene that is attached to a carrier.
