I would just add that if you are on the upper size range for the XLs like 12 or 13, a boot with a lower profile would be helpful. The 390s are adjustable to help them fit better, but I found that my size 12 boots seem to just fit the ankle strap. I love the bindings but if I had a really chunky size 12 boot It would be a real pain.
