Ariat Boot Company's 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. This Ariat Fatbaby boot is anything but hard to spot (and once you spot it - you'll want to bag it!) Fatbaby boot features a brown ostrich print leather foot with protective saddle vamp under an 8" green, fancy stitched leather shaft. Blue fabric lining and taped inside seams. Cushioning, energy-return EVA footbed is removable. Moisture-wicking, anti-bacterial footbed liner wicks sweat away and blocks odor. Double stitched welt. 1 1/2" Duratread heel. Round toe. Shaft circumference is 14" (based on a size 7B).
