Abstract: A shoe having a closure system is disclosed. The shoe has an upper and a sole attached to the upper. A first strap member is attached to the medial side of the shoe at two longitudinal locations. A second strap member is attached to the lateral side of the shoe at two longitudinal locations. A first adjusting member is slidably coupled to both the first and second strap members. The first adjusting member is slidable along the first and second strap members towards the front of the foot to tighten the upper about the forefoot of the foot. A second strap member is slidably coupled to both the first and second strap members. The second adjusting member is slidable along the first and second strap members toward the rear of the foot to tighten the upper about the ankle and heel of the foot.

The flap has a first position wherein the flap is positioned in an overlying relationship to the upper and a second position wherein it is positioned in an overlying relationship to the sole such that the ground engaging element can contact the surface upon which the sole is being used.

Abstract: A bladder assembly for an athletic shoe and having at least first and second chambers. The chambers are independently and separately pressure adjustable by the user to conform to different concavity areas of his foot, such as the arch, ankle and metatarsal areas, to thereby enhance fit, comfort and athletic performance. Both chambers are inflatable by the same articulated on-board pump and deflatable by the same on-board depressible plunger. A dial on the lateral side of the upper allows the user to select which of the chambers is to be pressure adjusted, that is, which of the chambers is in pressure communication with the pump and the plunger. When the dial is in a neutral position, accidental inflation or deflation of either chamber is prevented.
