I don't know, butIt shouldn't be too much. If you buy boots there, they'll keep stretching/molding/grinding them until they fit properly for free, so it shouldn't be all that much. Those guys know what they're doing-sold me boots four seasons ago, when I was 13, and they did a good enough job that I still have the same boots, and love them to death. (Salomon X-Wave 10s, and no, my feet haven't grown very much since then.)
