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.
Four pastern straps (two pairs in your preferred colour)
Small – Fits boots size 000
