You might be able to pull it off with a little more angle for your bindings and get the 158. Either way I think you'll be risking some toe drag, a wider board will take care of that.

doiung it daily brotha,i rock size 12 boots on this machine and it handle pretty well. if u can rock a duck stance i would recommend it but if not u can get risers for ur bindings which will take care of the toe drag.
