Reduces stomping and protects hooves from fly irritation. The boots are made of lightweight, breathable mesh that covers and shields the legs, helping prevent hoof cracks and other issues caused by flies. Highly recommended by Farrier and Vet. Universal size with a secure fit. The design fits close at the bottom near the coronet band and is looser on top, forming an inverted cone that cannot pass the hoof. No flies can access from the top. After field surveys, this is a universal size with a 2.7-inch wide vertical Velcro seal that stays put and adjusts to fit most horses. Stay-up stability with dual metal stays and ventilation. Easy to attach and comfortable to wear, these boots do not sag due to sewn-in dual metal stays. The flexible metal is durable and works with a loose fit to avoid rubbing. Lightweight, breathable mesh provides ventilation for ongoing comfort during wear. Easy wearing and durability. Easy to put on and take off, and simple to wash. Follow the User Manual and adjust the Velcro to stay above the hoof; incorrect placement may cause detachment. Strong Velcro and plastic mesh withstand summer rain, mud, and wind. Ideal for horse facilities including farms, paddocks, pastures, stalls, and barns. Use scenarios: - Turnout in fly-prone pastures to reduce stamping and protect legs. - Training, riding, or grooming sessions where leg protection is needed without rubbing. - Wet or muddy days in stalls or paddocks to keep legs clean and shielded from moisture and debris.
