@ Anaru, Do you also have a wide board or do the 12's still fit on a regular board. Is the 12 similar to an 11 from a different brand?
No I don't. I ride a lib tech dark series 159 and a skate banana 154 and not in the wide sizes. Don't have any issues (that I notice) with heal or toe drag.
Only other boots I've had we're some Salomon's size 12 but fit was fine.
