I would say a lot. Shopping, malls, night out to casual dinner, etc.. I'm a Nike fan boy as every sporting items of mine are Nike. I would not consider buying Adiadas, Filas, Reebok, etc.. of any sort.
Trust me, I'm a Nike fanboy myself. But wearing them casually just doesn't seem to work. At one point I did use my ballistecs every single day. Then I found supra and never looked back since.
