Thought you might be interested to see some photos from my barefoot horses, currently walking from Chile to Venezuela. They have been barefoot with occasional booting (for two of them) for more than 1000 miles now.
Some history here
These are just walking pics, not proper hoof pics, so just for interest.
The buckskin´s fronts have definitely strengthened and she is sound without boots over packed ground, even gravel, and deep sharp sand. Large gravel, rocks, or uneven hard ground (like dried clay mud) : she prefers her boots on. However, as the boots are now wearing holes in the soles, I am half-considering getting her back into shoes. Very conflicted on this one.
The grey has dropped a hoof size and is barefoot nearly 100% of the time, even over very rocky ground. She continues to have a bit of flaring on the fronts but much, much less.
The bay is a conundrum. On the face of it she has the best hooves, with thick walls and thick soles. However, she is the one that stumbles the most when there are rocks. Her toes have been brought back a lot and her heels are popping up, but could it be good to get her back into shoes to give her soles a break? We don´t have hoof boots for her. (yes, I know actual useful hoof pics would help, sorry.)
However, one thing for sure is that their frogs are all a million times better. Which is nice.
