Curlin's Horseshoe Beat Him to the Hall of Fame

The square-toe glue-on Polyflex horseshoe design dictated by Curlin's 2008 campaign needs

A highlight of last week's Hoofcare and Lameness/Hoofcare@Saratoga reception for the Ride On! exhibit at the National Museum of Racing and Hall of Fame was a little piece of plastic with a big story to tell.

Oklahoma horseshoer David Hinton had been scheduled to be with us but had to change his plans; he will be with us this week at the Parting Glass at 7 pm (August 11) instead.

David shoes for the Asmussen Racing Stable and flies all over the country. Last year, he was working on Curlin when the champion colt was stabled at Saratoga and training for the Woodward and Jockey Club Gold Cup as part of his campaign toward the 2008 Breeders Cup and becoming North America's richest-ever racehorse.

Trainer Steve Asmussen had success with the Polyflex shoe developed by Saratoga horseshoer Curtis Burns on other horses but he only wanted a square-toed "Silver Queen" type glue on for Curlin. The problem: the Polyflex shoe had a round toe.

Changing the mold for one horse in the middle of the busiest time of the year was a tall order for the Polyflex team but somehow, but mid-summer, a prototype was made and put in Hinton's hands to try on Curlin. Not only did it work, the company soon added the design as an alternate model and it is selling well.

Curlin went on to wear the shoes for the rest of his career. Asmussen starter Kensai wore Polyflex glue shoes a week ago when he won the Jim Dandy, although I don't know if they were square toes or round toes.

One of the square-toe shoes that Curlin wore in the Jockey Club Gold Cup, when he passed the $10 million earning mark, was presented with documentation to the National Museum of Racing last Tuesday, on behalf of Stonestreet Farms, owner of Curlin. Burns and Hinton worked behind the scenes with Hoofcare and Lameness to make this happen for the night of the reception, which was sponsored by Life Data Labs.

The shoe was presented to curator Beth Sheffer, who was thrilled to receive it. She said it was the first glue-on shoe the museum would have in its permanent collection, although they currently have on display Big Brown's Kentucky Derby Yasha shoe on loan from Ian McKinlay.

Sheffer revealed that the museum had received the extensive shoe collection of Calumet Farm in Kentucky and its late trainer Jimmie Jones. The collection is in storage.

The Ride On exhibit contains examples of horseshoes, hoof boots, and pads used to overcome different lameness problems, especially laminitis, in horses. Included in the exhibit are two handmade shoes by Michael Wildenstein FWCF (Hons), adjunct professor of farrier science at Cornell University College of Veterinary Medicine, and a selection of rail and roller motion shoes by Dr. Scott Morrison of Rood and Riddle Equine Hospital's Podiatry Clinic in Lexington, Kentucky. Also included is the Soft-Ride hoof boot, which Dr Morrison helped to develop for laminitic horses.

Dr. Morrison will speak on Tuesday, August 11 in the Hoofcare@Saratoga series at the Parting Glass, 40 Lake Avenue, Saratoga Springs, at 7 p.m.; Michael Wildenstein will speak on August 18 at 7 p.m., with a farrier-only session in the afternoon. Admission to both lectures is free; seating is limited.

Greetings from the Gluegrass: Will Big Brown and Pyro Choices of Designer Footwear Turn It Into the Ken-STUCK-y Derby?

Risen Star and Louisiana Derby winner Pyro impressed a lot of people this winter. He did it wearing glue-on shoes called Polyflex, shown here on stakes winner Malibu Mint. Little Belle won the Ashland Stakes at Keeneland wearing these shoes last week; that's the track that Pyro will run on today. The shoes are more or less transparent, with a yellowish hue. They have a steel wire core which is shaped like the foot in a special mold, then urethane is poured in to the ideal shape. A steel toe insert completes the kit.

Glue-on horseshoes are the stuff of legend this year as at least two of the Derby favorites flaunt their footwear on the road to the Triple Crown.

In the Southeast corner, we have Big Brown, winner of the Florida Derby by a landslide in spite of recovering from heel wall separations in both front feet. The photo (bottom of this post) shows a typical injury of this type, usually caused by a subsolar abscess, trimming too short, or training and racing on hard tracks (or a combination of these factors).

Ian McKinlay, the New Jersey quarter crack specialist who repaired the detached wall on the first foot, said that the colt "is not a bad-footed horse" and just needed cushioning on the inside heel where an abscess had been. "Chances are, it will grow down, on both feet, and he'll be fine going into the future," Ian said yesterday. "His trainer knows what he's doing."

Ian's solution, which we hope to show on the blog, is a standard one; he says the injury is quite common among both Standardbreds and Thoroughbreds. He cleaned up the wall from the quarter back to the heel and put a gum rubber insert under the deficit. There's one heel nail holding the glued shoe from slipping, along with a copper clip (the PMMA adhesive sticks very well to copper) on the outside. The gum rubber material is like window caulking; it acts like a gasket. The glue-y shoe is a regular race plate.

(To read more about Big Brown's fancy footwork, see photo below and scroll down to posts and photos from earlier this week, marked April 8.)

And in Kentucky, all eyes will be on Pyro in the Bluegrass Stakes today. I didn't know until this week that Pyro won the Risen Star and Louisiana Derby wearing Curtis Burns' Polyflex all-urethane shoes, and he will apparently have them on today, as well,to run on Keeneland's Polytrack. Pyro's gluesmith is Steve Asmussen's regular horseshoer, David Hinton.

What's in a name? Polytrack seems to agree with Polyflex; you'll agree if you watched Kiaran McLaughlin's trainee Little Belle win the Ashland Stakes at Keeneland last Saturday, with Curtis's see-through shoes glued on her fast little feet.

And who gets the last word in this sticky story? That maven of the media, 2007 Belmont Stakes winner Rags to Riches. It seems R2R, who now resides at Ashford Stud in Versailles, Kentucky, was bred to Giant's Causeway last week. To celebrate her future marehood, farrier Steve Norman pulled her raceplates and replaced them with glueons which will stay on for a cycle or two. This is called "transitional shoeing" and is meant to encourage sole growth before she goes barefoot.

Traditionally, fillies and mares coming from the track have their shoes yanked off and they go straight to a barefoot lifestyle. This usually means gimping around the breeding farm for a number of weeks, since the feet are often cut quite short at the track, and the soles can be thin, until the feet toughen up.

One horse who I cannot imagine in gimp-mode is Rags to Riches.

Note: There are special shoes for gluing on racehorses, such as the Polyflex shoes or Sigafoos shoes, with cloth cuffs. Farriers can also glue on or glue-and-nail normal plates or shoes. There are some amazingly creative people working on these horses.

Thanks to all the farriers and trainers who contributed to this and other posts. I know they had a lot to do this week but most took the time to talk because these new shoes are past the "experimental" stage and are now considered creative equipment adjustments. We've come a long way.

This foot has been cleaned up after being blown out by a subsolar heel abscess, similar to the problem that necessitated glue-on shoes for Kentucky Derby hopeful Big Brown. Ian McKinley padded the exposed heel with gum rubber and glued window caulking like a gasket to hold it in so the area is cushioned. At this stage in the procedure, dead or hangnailish wall has been removed. This is NOT Big Brown, who is now well on his way in the healing process. (Ian McKinlay photo)
