My elderly thoroughbred is out 24x7, you'd indicated these should stay on and they sure do! Well, he does occasionally slip one off, but 99% of the time they do stay on and in place. The fetlock shields are the best I have ever encountered. They stay in place to do the job nicely. Fabulous products, both of them!! Thanks so much for creating these and my thoroughbred thanks you. I love these things!!
