Ariat Boots exclusive ATS technology supports and cushions as you move, promoting good posture and reducing fatigue. Comfort technology is what we love about Men's Ariat Boots! At the core of ATS technology is the Ariat ATS composite shank. This patented shank design reduces skeletal and muscular fatigue and injury. Mid-foot support reduces metatarsal stress. The forked shank design allows natural forefoot flex. The ATS footbed has a low-friction surface to protect from heat build-up and blistering. Shock-absorbing gel forefoot cushion reduces skeletal impact stress on knees, hips, and lower back. Cupped footbed chassis offers torsional stability. The Nighthawk boots feature a smooth tan leather foot under a matching 13" leather shaft with blue embroidery and tan, distressed leather overlay. 1 1/2" horseman heel. Re-solable Goodyear leather welt. Hand nailed, vegetable tanned leather outsole. Easy-on pull straps. Updated with square toe profile. Imported.
