I have ridden all of O'Briens new bindings and they are all very comfortable. I currently ride the Argon bindings and I can finally ride as long as I want without having to stop because my feet hurt!!
i tried them on, and they were super comfortable, i'm just worried cause they were really stiff, and i want to be able to bend easy without to much restriction. I assume that they would be better after they were worked in though.
