Purchased at the time of release and stored in a dark place, compressed in a compression bag. I started wearing them in the summer of the year before last. I've only worn them for about six months. I wore them in rotation with other basketball shoes. There is scuffing on the openings of both shoes. There is yellowing on the soles. There are scuffs on the heels and in various places. The insoles are unused because I used different ones. After wearing them, I put in desiccant and stored them in a compression bag after they dried.
