I don't shoe my horse and ride my mare with easy boot epics.
They aren't perfect, and yes I've had a few problems. We usually day ride 10 to 15 miles a weekend. I've had the boots over a year and always ride with her in boots.
I've had a boot come off twice, but one time I had the boots on the wrong feet, so, I'll take the hit for that one. That time I tore off a gaiter.
Both times they came off while galloping. I've never lost one due to mud or trail conditions, and both times we were galloping on good flat trails. I haven't tried a pin through the buckles, but I think that might prevent the problem.
They're not the easiest to put on, and because of that I'm usually the last man up, something my military mind has a hard time dealing with. I don't like people waiting on me.
I find boots a very good alternative to shoes for the amount of riding I do. If I were riding every day then I'd have to think more about shoes.
I'm going to try a pair of Renegades next as I hear they're quicker and easier to get on and off.
