These unique training boots are made from Storm EVA carbon, an exclusive and highly flexible material. Their ergonomic shape and perforated structure allow for a perfect fit to the horse's leg and ensure maximum comfort. Lightweight, durable, and protective, these versatile boots are of remarkable quality. The mesh fabric provides constant 360° air circulation and even distribution of heat emitted from the horse's leg. The ultra-soft fleece lining offers ideal protection for joints and tendons, prevents pressure points, and ensures optimal comfort. The training boots are equipped with a robust Velcro fastening system that allows for easy on and off while providing an ideal hold. Size M: 2 Velcro fastenings, sizes L & XL: 3 Velcro fastenings. We recommend washing the boots by hand or on a low-temperature cycle in the washing machine, with the Velcro fastenings closed, on a gentle wash setting.
