Abstract: A shoe including a plate capable of being deflected in a direction substantially perpendicular to the major longitudinal axis of the shoe, an arch bridge integral with the plate and a substantially air-tight enclosure having at least two portions that converge toward each other relative to a vertical central axis of the air-tight enclosure to form an apex.

Abstract: A shoe includes a rear sole support for receiving a replaceable rear sole to provide longer wear. The shoe may also include a flexible plate supported by the rear sole support between the heel and the rear sole to reduce midsole compression and provide additional spring. A mounting member secures the rear sole to the rear sole support, and a locking member prevents rotation of the rear sole relative to the rear sole support during use. The replaceable rear sole and the flexible plate allow the shoe to be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.

Abstract: A shoe has an upper, a foot support region positioned below at least a portion of the upper to support the bottom of a user's foot, a sole secured below the foot support region, and a flexible member positioned below at least a portion of the foot support region and above at least a portion of the sole. The flexible member has a top surface, a bottom surface, a peripheral portion, and an interior portion. The interior portion of the flexible member deflects in use in a direction substantially perpendicular to a major longitudinal axis of the shoe. At least a portion of the peripheral portion is restrained from movement relative to the interior portion in a direction substantially perpendicular to the major longitudinal axis of the shoe.

Abstract: A shoe includes a heel/rear sole support receiving a rotatable and replaceable rear sole to provide longer wear. A flexible region positioned between the heel and the rear sole reduces midsole compression and provides additional spring. The flexible region is preferably curved or convex in shape and may be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.

Abstract: A shoe includes a heel support for receiving a rotatable and replaceable rear sole to provide longer wear. The shoe may also include a graphite insert supported by the heel support between the heel and the rear sole to reduce midsole compression and provide additional spring. The replaceable rear sole and the graphite insert allow the shoe to be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.
