They run narrow?! You must have small, small feet...I wear a size 10 boot and have to wear Large bindings because of the wide width of my Zoom DK's. I have Forum and Burton Bindings and a Large binding fits a size 10+. A Medium binding on the high end is a size 11 and still would not fit these fat boots lol and I don't have wide feet naturally. Trust me bro, these are some of the widest boots on the market but they are comfy and I love my DK's.
