Size 8, sometimes size 9 (Canadian, I guess the same as America) , depends on the brand, and I'm not wearing shoes now, but the shoes I wearing for skateboarding are my trusty Cricas, and for running I wear Adidas (sp?).
Need new skating shoes soon.

Wow, big feet for a 13 year old. I'm 14 and my shoes are 4 sizes less than yours.
Meh, I guess I have small feet.
