ABSTRACT:
A stability device that increases foot security on the footbed of a shoe, provides lateral or medial stability, shock dampening, and optimizes flexibility. The stability device includes a resilient bladder insert having a horizontal sole portion underneath a wearer's foot, and a vertical foot portion positioned to a lateral or medial side edge of a wearer's foot. The horizontal sole portion and the vertical foot portion are in fluid communication and are proximal the first or fifth metatarsal regions of the foot. The stability device can be generally L-shaped to cradles a portion of the foot. A compression force of a foot landing onto horizontal sole portion causes an increase in fluid pressure in the foot portion which stiffens the veridical foot portion forming a bumper-like wall for absorbing side impacting force from the foot and serving to keep the foot on the footbed.
