Embodiment Construction

[0023] Detailed description of the preferred embodiment

[0024] figure 1 An article of athletic footwear 80 including a powered cushioning and motion control airbag system 10 is shown in accordance with the present invention. The shoe 80 consists of an upper 75 covering the wearer's foot and a sole assembly 85 . The air bag system 10 is contained in a midsole layer 60 . An outer sole layer 65 for contacting the ground is secured to at least a portion of the midsole layer 60 to form a sole assembly 85 . A sock liner 70 is preferably disposed on the upper portion 75 of the sole. Depending on the midsole material and performance requirements of the shoe, the midsole layer 60 may also be formed partially or completely in contact with the ground surface so that some or all of the outer layer layer 65 may be omitted. The air bag system 10 is disposed in the heel region 81 of the shoe 80 and is encapsulated or contained therein by any conventional technique such as foam in a cut...

Abstract

An article of footwear with a bladder system providing cushioning and dynamic motion control in a multi-bladder system. The bladder system gives the needed amount of motion control by stiffening a portion of the footwear in response to the individual user's side-to-side motion. When used in the heel, the bladder system takes into consideration a center-of-pressure pathway of the foot to increase medial stiffness in response to lateral-to-medial rotation of the foot, so the more a user pronates, the stiffer the medial portion of the footwear is made. The bladder system provides comfort and control without the extra weight and bulk of prior art support structures. The bladder system dynamically changes the stiffness of a portion of the footwear when pressure is applied thereto, and returns to equilibrium when the pressure is removed.

Description

field of invention [0001] The present invention relates to a product of footwear having a powered variable motion control and cushioning airbag system. During walking, running or other sports, the airbag system provides different resistances to the left and right movements according to the strength of the left and right movements. Background of the invention [0002] Typical running involves the runner landing on the outside rear edge of the shoe in the heel area, followed by a downward turn toward the middle as the foot continues to stride. As the foot strike continues, the foot stops downward rotation as the foot swings forward and begins to rotate backward so that the foot reaches a neutral position. From a neutral position, the foot swings forward to the forefoot area, where toe deviation occurs on the ball and front of the foot. Toe-off typically involves the toes on the midfoot leaving the playing surface when the foot leaves the ground to start a new cycle. [0003...
