So glad I purchased these! I have tried multiple other brands of boots and could never find one that didn't twist or flop around. My horse has wide hooves so the Easyboot wide sizing option finally fits his hooves properly. I have tested them in the ring and on trails with mud, rocks, and sand. The sand and rocks do not get into the boots since they are a snug fit around the hoof wall and they stayed perfectly in place at all 3 gaits. They are a very slim profile and wash/dry quickly after wet muddy rides. All I have to do is hose them off and they are dry by the next day! The largest size (3W) is slightly small for my horse according to the sizing charts so I hesitated in purchasing. They are difficult to get on and I needed a rubber mallet the first time but seem to have stretched slightly to conform to my horse's hoof. It's worth the effort for the security of knowing they will stay in place during any conditions. Also recommend Mueller tape for extra grip on the hoof for long rides. Con:Larger size options would be appreciated for large wide barefoot hooves!
