Have a look at Derek Poupard's work on this 4 year old OTTB that he put Hoofcast on to provide stronger nailing and heel support. He chose the Kerckhaert Century Unclipped Aluminum Shoe to go with the 3D HoofCare Full Mesh Pad to complete the package. He decided on the Full Mesh Pad with the soft FootPro DIM 20 Impression Material because of the gravelly and sometimes muddy environment the horse lives in. The horse was much more comfortable with this support when the shoeing job was completed. Nailing and clinching with the Hoofcast material is just like working with good hoof wall. Derek used Liberty 5 Slim nails, a good fit in the Century Aluminum shoes.
