Abandoned footwear
Abandoned footwear is regularly found intentionally placed or littered in inhabited areas. There are many hypotheses about why footwear are found more than other types of clothing or why footwear is noticed more than other types of clothing. Shoes are more sturdily constructed than most other types of clothing so they will last longer after being abandoned outdoors. Leather shoes, for instance, are estimated to last for 25–40 years outside. Some shoe abandonment is intentional, as in shoe tossing, in which shoes are tied together by their laces and thrown into trees, over power lines, or over fences. Other intentional shoe abandonment is for the purposes of a memorial, as in the case of ghost shoes.
