Ariat exclusive ATS technology supports and cushions as you move, promoting good posture and reducing fatigue. 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. Ariat knows that your boots often do double duty - both for everyday jobs and weekend wear. They've introduced the Heritage Rough Stock, a boot that's built a little tougher than the rest. It features a full grain oiled rowdy leather foot and matching, fancy stitched 12" shaft. Easy-on pull holes. Leather lining. Single stitched Goodyear welt. Square toe.
