The present invention provides an improved horseshoe, which comprises a hoof engagement surface that is provided with an unevenness and makes contact with the hoof in such a manner that the shoe will fit more closely to and immovably against the bottom of the hoof. The unevenness provides an anti-slip interference with fibrous material of the hoof to lessen relative movement between the horseshoe and the hoof, both during assembly thereto by a farrier and during galloping of the horse, desirably inhibiting shearing stresses being placed on the securement nails. The anti-slip interference is provided by an array of bumps or hemispherical shaped domes that project upwardly from the hoof-engaging surface to displace fibrous hoof material and complete an interlocking engagement therewith in an amount sufficient to inhibit relative movement but not create discomfort to the horse.
