Thanks to the stiff carbon-fiber tongue and “stringers” that laterally reinforce the Zzeros, these ultralight four-buckle boots felt surprisingly solid and stiff bombing down steep shots around Loveland Pass. 7 lbs; dynafit.us
Bonus: Grooved guides in the toe make the boots much easier to click into the bindings than previous Dynafit models.
Bummer: They work best with Dynafit bindings.
