When deep fresh snow in the backcountry is calling our name we buckle-up the Tecnica Cochise 110 Dyn Alpine Touring Boot. This boot uses a lightweight but powerful C. A. S. shell to balance uphill comfort with downhill performance. Additional balancing of performance is provided by the powerful walk mode level and dual setting top buckle that let us lock our foot in on the skin track and then crank down the fit before we drop in to dreamy powder turns or scary exposed hop turns.
