It is the simple features of the shoes, which make them the favourite of the horseshoes in America. This shoe, which is a great shape, fits with the minimum amount of adjustment. They are always level, straight from the box, every shoe being the same as the last - Kerckhaert means consistency. They have clean, open nail holes, where the nail fits perfectly, reducing the chance of lose shoes. When you select either a SX7 or Standard shoe, it is made for America by The Royal Kerckhaert Horseshoe Company.
