The PRO ASCENT is a super technical boot for big walls, ridge climbs, heinous approaches and "running boulders". They will protect your feet for rugged cross country rambles and have a generous fully gusseted tongue to keep out annoying grit and debris. Sticky Spinne suction cup climbing rubber sole is secure on all types of terrain and is backed by Scarpas medium stiff Flex Plus midsole for a little extra support. With PRO ASCENTS on your team you can stand in aiders all day or pound the trail with a heavy haul bag or pack and not "burger" your feet. Made with the same high quality materials as the low-top LITE ASCENTS - with Crosta leather uppers, Dri-Lex lining, high friction rubber toe and heel rands and a low profile, no snag lacing system. You will appreciated the higher cut to protect and support your ankles - in wide cracks and talus. Next time you're contemplating a 4 hour lead or hiking up Tenaya Canyon with a haul bag - give your feet a break and wear your PRO ASCENTS!
