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 new RigTek work boots feature a smooth leather foot under an 8" nylon lace-up shaft. Padded collar offers added comfort. Block heel. Moisture wicking lining. Single stitched welt. Safety composition toe.
