These bindings are amazing. The soft heelcup and tension system put them ahead of everything else out there. Once you ride them you won't go back to rigid plastic injection molded bindings. I'm so surprised they haven't caught on quicker, could be the price point(or the fact they don't give them away to every pro). I got rid of my Rome 390s and Union Force they couldn't hold a candle to the relays. Definately one of those tech advancements that makes riding easier, more expressive, and more comfortable.
