Keep your feet moving comfortably in the Series 100 8 Boot. Manufactured with the highest quality materials these boots will stand up to the tests of time. A premium memory foam insole adds a layer of all-day comfort for those long demanding shifts while the breathable liner of the boot wicks moisture and regulates temperature. Quality black full grain leather and 1000D Cordura upper of the Series 100 Side Zip Boot can be pulled snug with the quick and easy NATO speed lace system. The triple-density rubber foundation and an arch made from a durable compound will hold up to the rigors of fast-roping. All of our boots are based on true U.S. sizing to provide the perfect fit.
