Designed to fill the gap between our approach shoes and mountaineering boots the Scarpa Zodiac Tech GTX Mountaineering Boot boasts a versatile design that makes the most of all our long approaches below treeline long scrambles up scree-covered alpine environs and even the occasional front-point action up icy couloirs and across glacial valleys. The Zodiac Tech is a slightly stiffer version of the Zodiac Plus making this boot the better option for those who plan on spending more time above treeline on snow and glacial ice.
