The Easyboot Rx is just the prescription for horses requiring a lightweight therapy boot that offers stability and support. The Rx is ideal for horses suffering from chronic lameness, laminitis, founder, navicular and other lower limb/hoof problems. Each boot comes fitted with a 6mm Comfort Pad to provide immediate relief and additional sole support. Size up one size if you plan on using bandages or 12mm Comfort Pads with the Easyboot Rx. The Easyboot Rx lessens fatigue during trailering and is excellent choice for horses that stand on hard surfaces for extended periods of time. As with any hoof or leg related injury, consult your veterinarian or hoof care professional for diagnosis and treatment recommendations. The Easyboot Rx is not intended for large turn-out or riding.
