The Tecnica Zero G Guide is an alpine overlap constructed, all mountain resort boot with a walk mode, rubber sole, and 'tech fittings' for use in the backcountry. As such, it will appeal to those looking to ease the transition to touring equipment and looking for the ultimate in downhill support, whether to support high speed and high energy expert skiing or to support rudimentary technique of more beginner backcountry skiers.
