Cabrinha have released their new "backless bindings" called the Sync.  This new design by Cabrinha is nearly a crossover between a Foot Strap and a Binding and aims to give a better connection and direct feel between the rider and the board.  The Sync has a lace style top, which when you pull it tight fastens your foot inside, and also changes the binding to mould to your foot better.  Traditional Foot Straps have attachment points on the left and the right with a strap over the top.  The Cabrinha Sync locks your foot in by spreading the load from the top lace to the bottom lace giving the whole side and top of your foot support.
