Beware of those bindings.... Strap them on your board, slip your feet into them, and then lean forward. If you notice that the heel of your boot lifts off of your board about an inch you'll know why they are only $69
The mounting plate is made of plastic and it flexes something terrible. This may bother some and not others, but to me this just kills the responsiveness of your board when edging toeside. It's almost like telemark skiing on your wakeboard.
I bought these boots from the same place and ended up just giving them away. They will probably be decent boots for a guest board or something, provided your guest has the exact same sized foot as you.
