Built with a sense of adventure and discovery, this expedition-worthy trekking boot delivers quality, comfort, and performance for backcountry travel. A composite three-part midsole supplies excellent underfoot cushioning with a solid chassis for stability on the trail. Vasque's exclusive Vibram Summit outsole lays down positive traction in rugged trail conditions and a premium, waterproof, full grain leather upper and Gore-Tex lining protect the foot from environmental extremes. Fit Profile: The Eriksson GTX is built on the Summit last, a combination last that uses a medium volume heel (designed to fit a wide range of shapes) with a straighter forepart. This last provides a positive heel lock pocket, excellent arch support, and rockered toe for less walking fatigue in stiffer boot.
