The Standardbred market has long relied on the half round style to train and race. The Kerckhaert design gives a better heel support and a much more realistic nail pattern to help with the performance of the horse. The excellent shape of the shoes minimizes the amount of work needed to get a good fit. A high quality steel provides excellent wear and support for the foot. 15 pair per box. Punched for 4-1/2 Race nails. Shoes are symmetrical (shoe fits left or right).
