**Remember to measure for the perfect fit.** Shoofly Leggins Horse Fly Boots are designed with a breathable plastic mesh with sew-in stays to help prevent sagging during use. For added durability and wearability, these boots feature heavy-duty Velcro and to help eliminate embedded wild oats, burrs and foxtails, the lower edge is finished with felt. These loose-fitting, chemical-free Shoofly Leggins are perfect for fly season to help prevent painful fly bites and to help reduce stressful stomping, which leads to hoof damage and leg fatigue.
