Serious big wall climbers and aid technicians need more than a climbing tennie. Enter the BIG WALL - with all the support and comfort needed for marathon pitches and sun-up to sun-down climbing. These beefy shoes won't punish your toes or deform your arches and will give you much needed confidence when moving from A3 hooks onto 5.10 friction. Count on built in free climbing power (a joy in wide cracks) with FS-Quattro sole and heel. Upper half is AirNet mesh fabric for ventilation and comfort with yellow waterproof split leather and abrasion resistant Amortex NT reinforcements throughout. Classic stiff midsole, padded tongue and tall rubber rand make this shoe a great choice for long approaches or descents and alpine rock and "hike and climb" days in the back country.
