Few people I know have a turnaround on gear as the footwear nerds. The year is split into multiple seasons, they buy a bunch of shoes for that season, wear them only a few times if at all, and when next season comes it all goes to the trash. Because next season is warmer/colder/wetter/drier, and next year same season the stuff is all out of fashion and they need to buy new models. It' sickening.
