My size 14 Vans won't fit in the XL 390's due to width issues. I would recommend trying to locate a pair to make sure.... 390's are kind of an interesting binding to fit imo.. Force bindings are a lot more straight forward with sizing, what you see is what you get.
I would def recommend Forces over 390's for a Raptor..... 390's are very soft park oriented bindings and Forces are a do it all binding that will last as long as the Raptor.
Grats on the Raptor!
