These are Great!
"These are a great find. I currently have a horse recovering from a pretty bad subsolar abscess. I don't want to keep him in hoof boots or vetrap and diapers all the time because of his hoof getting too moist. That's where these boots come in. I use these during the day, when he is on restricted turnout. They allow his hoof to breathe, and yet keep his sole protected. For the price, they are decent. One velcro strap has broken already, and the foam wears out pretty quickly, but I put a little vetrap on the outside, and that helps keep them intact."
