My horse wears Renegade Vipers on the front and Scoot Boots (a relatively new product) on the back.
The Renegades are kinda complicated, and it took a few tries to get the sizing right. Now that they fit properly, though, we have never had a single problem (300 or so miles and going strong).
The Scoot Boots on the back are my favorite thing. They’re lightweight, simple, easy to put on and take off, and have fantastic drainage. We’ve had a few issues with straps coming unscrewed (use locktite!), but the boots themselves have never even threatened to come off. They have just now worn through — same mileage as the Renegades, over very rocky trails, but they are a little thinner in the soles. I will be replacing them with more of the same, and plan to buy a pair for the fronts when the Renegades wear out.
If you just want an uncomplicated “spare tire,” the Scoot Boots are simpler and more lightweight. Slightly cheaper, too. I like both boots, though, and every horse is a little different. You may have to experiment some.
