A shoe having a dynamic fitting and shock absorption system. Disposed within the shoe is an insert defined by a sensing means including a U-shaped pivot bar that straddles a movable footbed. The bar has an upper end attached to a strap extending over the instep and forefoot. The opposite end of the strap is attached to the footbed. The bar is pivotally secured to the sides of the footbed. The lower end of the bar rests on the shoe sole. Movement of the footbed in a downward direction upon foot strike pivots the bar toward a position parallel to the footbed dynamically tightening the strap on the foot and distributing a portion of the shock load to the midfoot and forefoot.
