Need Help with Binding Size!!!!

I am looking at the 2013 Liquid Force Harley BuyWake.com Package, I'm not real familar with how the Liquid Force CT bindings fit. I wear a size 11 1/2 shoe but I don't know whether the bindings fit small or big. I can not find a specific size chart anywhere. I would like to place my order tonight if at all possible. Should I go with the 10-12 or the 12-15? Any help is appreciated

Try them on at a local shop, if possible. But 10-12 should be the right size.

I asked my son and he said 10-12 my he wears an 11 shoe and has the 2012 Harleys in 10-12 he says there is room to grow in them.
