A great protective over reach boot for training, as well as performance. Neoprene adds durability. The sturdy lining absorbs energy from overreaching while the Velcro secures the boot from spinning. Unlike rubber boots, you no longer have to worry about the pastern being rubbed raw from spinning. These boots are extremely durable and tear resistant making them a customer favorite. These boots can also be used for protection during side passing, pivots, and massive spin work, by flipping them upside down, placing them around the knees and hocks.
