Do they release just like an alpine binding?
While more than a decade of testing has proven the Dynafit to have a functional safety release that’s similar to alpine bindings, it is not the same. Alpine bindings may have more angles of release, and may have more elasticity (ability to absorb movement, vibration, and shock). Remember that for maximum safety, all ski bindings require careful release tuning. Tune binding release by setting to standard settings using height/weight charts, and ski a few runs. If you don’t pre-release (i.e., release while skiing, not falling), set the release a half number lower, and ski more. Keep reducing the release setting until you start pre-releasing, then crank back up 1/2 number. Do this individually for lateral (sideways) and upward (vertical) release. Ski all randonnee bindings more conservatively than you would full-on alpine bindings. In other words, ski without falling.
