Modern technology meets traditional design in the Pro Performance Hybrid Splint Boot with fleece lining. This boot is ideal for everyday protection during exercise or turnout. The Pro Mesh outer layer is extremely durable yet flexible. The entire boot is ventilated, making the boot extremely lightweight and allowing for nonstop airflow. The integrated strike area is built into the boot for improved fit and enhanced comfort. These boots are waterproof to the point that they float in a bucket of water, and feature a naturally hypoallergenic inner foam lining which resists mold and bacterial growth. The faux fleece liner is easy to maintain and ideal for sensitive horses. Can be used on the front or hind legs.
