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.
