I'd probably go with a little bit bigger board for a size 11 boot. Check out the waist width on some different boards... I'd recommend at least a 254mm waist width for a size 11... length depends on what you ride (shorter for park, longer for pow)... waist width is gonna be the most important for you because you don't want those big ol toes dragging!
I've been riding the machine for about 3 years now and it's hands down the best board i've ever owned. I'm 6'0" 160 and I ride the 154. There really isn't anything you can't do on this board,bombing groomers, rails, kickers, pow, it tames it all. The mountain is my playground and this board allows me do do basically anything that I want. Good board for any terrain. The new graphics are sick, get one while it's hot.
