Don't buy your boots online....don't buy your boots online, unless you have tried them on in the store, and even then I still wouldn't do it. I had a pair of boots that was really painful for part of a season, just because they didn't fit my feet. Flow bindings don't seem to have a large following in my experience. I understand wanting a box with everything you need from the foot down showing up at your door but if the boots don't fit you won't be happy. Get a board binding combo and get your boots later.
