A do-it-all WorkHog with a cowboy soul. Ariat's® ATS Max platform provides maximum torsional stability for reduction of foot fatigue and proper body alignment. The sole pairs a lightweight, cushioning EVA midsole with Ariat's® highly abrasion-resistant oil- and slip-resisting Duratread outsole for the ultimate combination of comfort and durability. Ariat's® unique, patent-pending U-Turn Entry System, allows easy entry and a true fit regardless of foot shape. This style was formerly model number 16916. Shaft Height: 10" Outsole: Rubber Upper: Full Grain Leather This style tends to run large. For an accurate fit we recommend purchasing a 1/2 size smaller than you typically purchase.
