i have a size 12 boot would i have a lot of toe drag?
Yeah most likely. Some times toe drag isn't a huge issue but if your toes hang over a lot you can definitely catch them when turning. With a 12 look for a waist width of at least 255mm or higher, probably 260mm would work well for you.
I've got a size 12 boot and the Evo 161 with a pair of Burton Elevator binding riser plates and I get very little, if any toe drag.
Palmer also has binding riser plates. You should definitely check them out as they work awesome for me!
