I rode my MFT/Morgan mix for five years barefoot, he was never lame a single day. That horse had feet like iron. My sis's QH has to go barefoot for the winter because of our insane winter climate (Bring on the global warming, lol), and he beats his feet to nubbins walking from his stall to the crossties and back. He gets shoes as soon as the farrier thinks it's safe for him to wear them, so he still has hoof to nail to. My new guy has better feet than his barnmate, and we gave barefoot a try with him after his first trim this summer on the recommendation of our farrier, but he seems a bit tender-footed in the arena. I hate to, but he may get shoes in some form or configuration, maybe just on the fronts. My grandma leaves both of hers barefoot, but they're pasture ornaments. Her mare has foundered a few times (really long story), and dispite some rough times, her now unshod feet look great. I'm a fan of leaving horses barefoot if at all possible, but my sister's gelding has taught me that some horses just need shoes. Give it a try, and if he seems okay, keep it going. I'll have to do some research on Pete Ramey myself.
