About the Pastern Strap The pastern strap is designed to help prevent the boot from being pulled off due to an overreach, or sucked off when riding through mud. It is not intended to be the primary source of securement. The strap is made of very strong thermoplastic urethane (TPU) and is designed to stretch when placed under load, so the strap will not affect the horse’s pasterns if secured correctly. It also has a number of holes to provide the correct setting, depending on the thickness of the horse’s pasterns. Pack includes four pastern straps of the same colour. How to fit the Pastern Strap Make sure your horse is standing with its legs at 90 degrees. Once secured, you should be able to place one finger (large) or two fingers (small) under the straps at the front of the pastern. It is important to have the correct fit in order for the pastern strap to function correctly.
