Used burton step-in bindings with extra heel cups. These came on a board and I never used them. They are in good shape, all 4 heel cups work nicely. They are spring loaded and need to be preset to step into. The pads that came with them seem thin, as the screws stick down below the plate. I would either make new pads or use different screws before riding them. I can supply 3 or 4 hole discs. $100 includes shipping
