A heel-cup structure for climbing shoes having increased edge-contact properties and friction on uneven surface where the heel area has a protrusion around the outer sole area under the heel and rimmed indentation between the heel counter and the outer sole. The heel-cup structure with protrusion of the outer sole made of soft, polymeric, synthetic rubber material provides a device to latch onto a thin edge of the rock surface in contact, to effectuate edging and heel-hooking.

This disclosure relates to recyclable footwear. Components of an article of footweare.g., an upper and a solemay be secured to one another using one or more cables. The article of footwear may also comprise a heel counter and/or toe cap, which may serve as anchor points for the one or more cables, improving stability. Thus, the article of footwear may be constructed without the use of an adhesive and may be easily disassembled, improving recyclability. Methods of recycling articles of footwear are also disclosed.

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.
