A therapeutic support horseshoe includes a resilient, flexile moldable material formed in a U shape with an anterior segment from which opposing first and second side segments continuously extend to opposing caudal ends separated as an open heel and a pliable, metal rod-like reinforcer embedded in the flexile moldable material between opposing hoof-contacting and ground-contacting surfaces, the reinforcer extending from one caudal end, through the anterior segment, to the other caudal end of the horseshoe. The horseshoe so formed includes an inner side surface and an outer side surface between the opposing hoof-contacting and ground-contacting surfaces a slot formed in the inner side surface, approximately halfway between the opposing hoof-contacting and ground-contacting surfaces, and extending from the one caudal end to the other caudal end.
