Abstract
This disclosure relates to recyclable footwear. Components of an article of footwear—e.g., an upper and a sole—may 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.
