The 574.

No matter how well you think you know what something / someone looks like, this goes to show that drawing from memory (at least for me) always comes with some kind of inaccuracy.

These shoes - the New Balance 574 - are the same (model of) shoes I've been wearing since I was 18.  I think I've gone through three or four pairs in that time, but the same color, size, etc.  Still, though, I had a tough time with this sketch!
