A horizontal bearing surface best fulfills this requirement.” 1

The cup shoe is designed with a concave bearing surface, not only over the inner region of the web of the shoe, but also around the entire outer rim of the web (FIGURE 1).

The hoof wall is trimmed to accept this configuration using much the same method as the “mustang trim” that many barefoot enthusiasts are advocating.

The configuration of the cup shoe allows the nail to follow the angle of wall (FIGURE 2) with less lateral (outward) strain on the basal ends of the wall than there would be with a more traditional bearing surface (FIGURE 3).

By trimming the basal hoof wall at an angle approximately 90…
