The women’s flagship binding, the Opus is an aluminum heel-cup binding that has strength and rigidity in the heel, but is soft and forgiving everywhere else to make this binding flex for lighter riders. It adjusts in every way possible so that the rider can fine tune the fit for their boots and the lightweight injected straps evenly distribute pressure to eliminate pressure points. It’s a top-of-the-line performance binding that our top Pros ride because it’s responsive, light and super comfortable (not to mention bomb-proof).
