When deep snow blankets the backcountry we pull on the Tecnica Zero G Tour Boot and head for the gnarliest lines we can find. These boots offer a control-inspiring combination of a 99mm last and 110 flex that encourages us to air cliffs, slash wind lips, and charge through trees. When we want to head up for another lap the 55° of walk mode lets us stride easily so that we are still feeling fresh at the top.
