The Shoofly Leggins Fly Boots are a chemical free way to keep flies off your horses legs. Made from flexible, plastic mesh to allow air circulation, Shoofly Leggins are easy to attach, comfortable to wear, and will not sag due to their unique sewn-in plastic stays. They are easy to use and have heavy Velcro fasteners. They prevent painful insect bites and reduce leg stress from stomping away the flies. They prevent bot flies from laying eggs further protecting from hoof damage. They speed healing time of abrasions and wounds by allowing air flow to the area. They reduce inflammation and muscle fatigue caused by stomping continuously. They do not restrict blood flow, nor do they limit the range of motion. The new web-belt material at the bottom offers increased durability. Set of 4 boots.
