I am a 12 in remz. should i stay with the 12 in nihm or do you think i should size down. i am a size 13 in skateboard/athletic shoes but have no prolem fitting into a 12 remz. has anyone gone down a shell size but stayed with a larger liner. i'm also considering getting the 10-11 shell but using a 12 liner. perhaps i could do that and shave out some more of the toebox?
