he's talking about the bindings,
Dont buy boots online, go and try them on at a local store and see which one fits you best. Think there is a thread in the boots section that explains everything about how to buy the right boots and such.
Oh yah, If i was in your position i wouldnt buy it, buy used equipment locally so you can see for yourself in person before you buy it, that might not even be the real picture and the board could be crack and F-up you never know til you get the package. Spend your hard-earned money on something you can be sure of.
