Footwear or Footwear Accessory for Traversing a Range of Different Terrains

Abstract

A footwear accessory is used for traversing different types of terrain including a sole, a heel, and opposing sides. Each side has a support wall and an expandable portion joined to the support wall by a support rib. The expandable portion moves between unexpanded and expanded positions to increase contact area on soft terrain. The footwear accessory is generally used in a pair, where a user attaches one of the footwear accessories to each foot and/or existing footwear worn by the user. The user's bare foot or footwear (boot, shoe, etc.), for example, is supported by, and within a cavity defined by, the sole, the heel, and the sides. The user then walks and/or runs across different types of terrain wearing the footwear accessory.
