I keep an EasyBoot in my tack kit for when Gracie throws a shoe. That stops the unevenness AND the wear problem.
I've never tried one of those but have been with some people who did, and they had trouble keeping them on. I don't know if it's because the terrain is so rough here or because they didn't have the right size.
I had ordered some boots called "Old Mac's" designed by some guy in Australia, but they never came in. I'm going to see how the barefoot thing plays out and if it just doesn't seem to work will try ordering these again.
