Hummm...Boy's size 6 might be too short. I think that is the biggest boy's size. Since width and type of shoe also makes a difference it might work for boots designed for socks. You might try that at a store before online and see but generally, even if you have to go to small men's you still usually get a better price and sturdier construction. Here, this might help:
