binding sizes

Does anybody know what sizes the 2004 HO Sport Orbit Wakeboard bindings came in cause i'm thinking about buying a board that has those binding on them but the seller doesn't know what size the bindings are all i knos is that they need to fit a foot between size 9 and size 10.5 foot

Chances are it'll be small/medium/large. Ask the seller what foot size he is and how do the bindings feel on him.
