Abstract: A cushion for use inside footwear having an interior for receiving a foot of a wearer. The cushion includes a liner made of cushioning material. The liner is sized and shaped for reception on an interior surface of the footwear in a position for engaging the foot when the foot is inserted into the interior of the footwear for cushioning an interface between the foot and the interior surface of the footwear with which the liner is engaged. The liner includes a visual cushioning indicator for visually indicating the operability of the cushion to perform a cushioning function during an immediately prior use by the wearer and for subsequent use.

Abstract: An indoor exercise shoe which is lightweight and has an improved traction feature. The outsole of the shoe includes a primary midfoot element positioned to underlie the arch of the foot. Traction inserts of high traction material are mounted in openings in the primary midfoot element. The traction inserts project outwardly from the midfoot element for engaging and gripping a surface, such as the pedal of a stationary bicycle, under conditions when the midfoot region of the outsole is relied upon for traction.

Abstract: An exercise shoe is capable of adapting its fit while being worn. The shoe has a quarter which is split into an upper portion and a side portion on each side of the shoe. In the gap between the upper portion and each respective side portion is an elastic gore which will stretch to permit the upper portion and side portions to move apart from each other as the foot moves during exercise or should the foot swell while being worn. A comfortable fit may be maintained without manipulating the shoelaces. The elastic gore has a substantial resiliency to pull the upper and side portions of the quarter back together as the foot contracts to maintain a secure fit.
