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.
