When it comes to foundered horses what we found through the years is the Equinety Horse XL really helps with the sole depth. It's not that it is going to help necessarily with the rotation specifically as a first phase, what it is going to do is it is going to help with the overall hoof quality and the sole depth which is going to support the coffin bone. Ultimately this just gives your farrier more to work with in a shorter amount of time.
