Abstract: A visual wear indicator is disclosed capable of giving a visual indication of the degree of wear on an athletic or other type of shoe. In general, the visual wear indicator may operate by having two different colored regions, each having a viscosity which varies a function of pressure. Before pressure is applied, the boundary between the two regions is clear. However, over time, as the midsole and/or outer sole of the shoe wear away, the pressure exerted on the visual wear indicator increases during activity. As the pressure increases, the viscosity of the regions eventually decreases. When the viscosity decreases, the regions bleed together, and the boundary between the regions becomes less clear. The degree of mixture between the regions may be calibrated to give a clear visual indication of when the shoe has worn down to the point where the shoe is unable to provide a desired level of support and stress absorption.

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.
