Hey, I just bought size 7 boots by Zuma/Spice and I'm looking to buy the K2 Moment snowboard 138cm with these bindings. I normally wear a size 5.5 sneaker so I was about to buy the small bindings but noticed the size chart says that for boot sizes 6-10, go with a medium binding. Do I assume the sizing is similar between brands and buy a medium binding?
