Here's Pletcher's take on the bar shoes:

"He won't run in them, but he has trained in them," Pletcher said. "It's not something new. He's had bar shoes, or similar shoes, since July. I'd say that in the last year, for 10 months he's trained in bar shoes. He might not need them any more, but I'm not going to take a chance now."

Thanks to "HoofBlog" for the heads-up!

Kinda strange no one's noticed them (apparently) until now.
