Abstract: A plastic shoe for horses to be secured to a hoof in conjunction with exposure to a thermal operation includes a sole part having an upper edge and being constructed substantially in the shape of a horseshoe for placement under an edge of a hoof. A wall part is secured to the sole and protrudes from the upper edge for laminar joining to a conical outer surface of the hoof. At least one of the parts is constructed of material being shrinkable under the effect of heat.
