The shoe design and rationale has already been explained in previous posts but this serious of photos will show you a horse that is NOT BIG BROWN, but that received a similar shoeing solution. Ian McKinlay has provided these additional photos to give people a broader view of how streamlined and non-intrusive the repair process is, compared to the older ways of bar shoes and laced and layered patches.
A blog comment last week brought up a good question, regarding his ignornance that Pyro had won his two previous starts wearing glued-on shoes. A few years ago this might have been a handicap, but that racing observer wondered if shoes shouldn't be disclosed to the betting public because high-tech enhancements might offer an advantage to a horse, similar to the new Speedo "skin suits" with ultrasonic welds instead of seams, which will be used in the 2008 Olympic swimming competitions. That is, unless they are ruled to be performance-enhancing equipment.
The shoe (race plate) package ready for application. The heels are fully cushioned where the wall has been removed. The copper "clips" are not clips in the sense of those used on steel shoes; they are providing more surface area for the adhesive. They are just thin tab-like strips of copper. Remember that this shoe will be glued on, there is no issue with nails having to penetrate the rubber.

The heel is rebuilt and the shoe is on. The temptation is probably to incorporate the heel repair into the shoe but the two have to maintain separate entities so that the shoe can be removed. The artificial heel will be trimmed as it grows down. Only the copper tab crosses the frontier between the shoe and the real/artificial wall. Remember that the padding under the heel is the full width of the shoe only in the heel area, which is why you see the black line fill with adhesive in the quarter.

I am not sure whether or not this horse had blowouts (wall separations) in both heels, possibly caused by subsolar abscesses, hard racetracks, or gait changes, so both heel walls were trimmed out and replaced with artificial wall. It's also possible that the the adhesive and heel cushion were used on both heels to provide symmetrical heel architecture and encourage normal gaits and stride characteristics.

Thanks to Ian McKinlay for sharing this technique, and for interrupting his work to take these photos. Racetrack repair technology is continuing to evolve as more horses are being shod and supported as their needs dictate. Ian is a career specialist in quarter crack repair and is bringing new ideas and materials to the racetrack to help horses stay in training. He is very generous to share information from the racetrack with the world through this blog.
