Made of full-grain leather, these brown boots are constructed with ATS technology. ATS, or Advanced Torque Stability, keeps you steady on your feet to help prevent foot fatigue and strain. A supportive, gel-cushion footbed with a heel stabilizer protects your feet from the abuse of walking on hard floors and unstable terrain. The footbed of these waterproof boots is also moisture-wicking to help keep your feet drier and cooler. There?s even a lightweight, ergonomic composite forked shank, so your feet will be further stabilized and properly aligned. Finally, a shock-absorbing EVA midsole provides yet another layer of cushioning for enhanced softness while wearing these slip-resistant boots. All these features work together, so your feet will feel better.
