The skywalk gtx logged as many miles in the 1980s as any boot, establishing the benchmark for a mixed upper, lightweight rig. For its contemporary incarnation we start with rough-out, 2.4mm leather, tanned right here in the u.s. We blend that with abrasion-resistant, breathable nylon mesh. The gore-tex waterproof-breathable liner manages the skywalk's internal climate, while a vasque pyrenees sole keeps you firmly on the trail. Old-school meets today's vasque...in the skywalk gtx. At Vasque, they are committed to making functional, innovative and aesthetic footwear that performs to the highest standards. Their ultimate goal is to make shoes that inspire you to get outdoors and embark on an adventure. Incorporating and developing new and innovative technologies into their boots is what keeps Vasque at the top of their game.
