Equi-Build Fast Set is a non-toxic, self-leveling liquid urethane material that adheres to the sole without the necessity for pads, sealing out moisture and debris and protecting the sole. Equi-Build stops heels from contracting, allows for faster, thicker hoof wall and sole growth, and takes pressure off wall cracks. It stabilises shoes - you will see no enlargement of nail holes. Setting time is 2-3 minutes.
