If i buy one of this, what binding should i buy if my boots are size 10 ?
I recommend a Burton EST binding vs a regular binding with the adaptor plate. With a size 10 you'll fit best in a size large. I would say go with something like the cartel est. It has a stiff flex and will work well on an all mtn/pow board like this. If you don't mind spending money also look at the CO2. To say a bit of money over these two bindings the Mission est bindings are a great value. They lack some of the bells a whistles of the more expensive models, but they have a medium flex and get the job done.
Justin is right on point.
