Sold in pack of 4. Now with VenTECH technology, the Elite Sports Medicine Boot is lightweight and multi-layered with a ventilated neoprene exterior and UltraShock lining. Ventilated neoprene conforms to your horse, allows heat and moisture to escape, and keeps your horse cool, comfortable and performing at its best. The boot provides 360 degrees of protection, safeguarding the cannon bone, tendons and soft tissue, and is proven to absorb over 26% of energy from hoof impact. The uniquely designed suspensory strap stretches with each stride, allowing full ankle movement and helping to eliminate hyperextension of the fetlock. The distinctive angle of this strap guarantees proper application, ensuring the boot provides maximum protection.
