Propper footwear was designed for long lasting comfort and durability. All of our boots are based on true U.S. sizing to provide the perfect fit. Leather and 1000D Cordura® upper can be pulled snug with a quick and easy speed lace system. Our triple density rubber foundation and an arch made from a durable compound, will hold up to the rigors of fast-roping. The 100 Series is a great value in footwear.
