These Ariat Woman's Antonia Western Boots are a beautiful, durable addition to Ariat’s Performance Collection. Setting the standard in professional riding boots, Ariat makes enhanced performance a primary focus. These boots provide ultimate comfort, strong durability, and solid stability without sacrificing style. 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. Comfort technology is one of the many things we love about Ariat Boots!
