DR are developed especially to take advantage of the new, advanced manufacturing techniques, invented and developed by the Kerckhaert family for producing top quality horseshoes. These advances once again put The Royal Kerckhaert Horseshoe Company ahead of other horseshoe manufacturers. Innovations like the Patented Radius clips, new crease designs found in the DF program, plus new concepts like the Grand Prix Hinds and DF Special, allows farriers worldwide to shoe to a higher standard, using Kerckhaert horseshoes of course. The DF program has expanded to meet the specific requirements of farriers, such as shoeing the Icelandic Horse and also horses with longer, narrower feet. These developments were so advanced that many registered designs and patents were taken out to protect all the developments achieved by The Royal Kerckhaert Horseshoe Company.
