I usually buy two pairs because I hate scuffing them. Ill wear one until they´re two fucked up to wear again and buy a new pair of something else (although I always keep clean all white ones in rotation) but know that I have a clean pair put away so I dont feel as bad.
I used to collect matchbox cars, then basketball cards, now I collect sneakers, I really dont see why that is so weird to people, Im sure you all collected something at one point no?
