If you are riding fast or long, you will want to use a boot that isn't likely to rub. IMO, your best bests are Renegades, Vipers, Easyboot Gloves, or Easyboot Epics.
I use Renegades and Vipers. One of my horses (TBx with white legs) has very sensitive skin and my Epics will rub her on long rides. I haven't used Gloves, but the gaiter is the same, so I assume the would rub her too. She is not normal. My other horse doesn't get rubs from Epics. I think most wouldn't. But if you have a sensitive skinned horse that is something to consider.
I love the Renegades, and even more so the new Vipers they are coming out with. No rubs, and they stay on through all kinds of crazy terrain, mud, and speed. Plus they are really easy to put on and take off, once you have them adjusted properly.
I think the Gloves are great too, if your horse has proper hoof shape and measurements that they fit like a glove. If they don't fit perfectly you may have boot loss. Also, since they have to fit so snug, some people have a harder time getting them on and seated correctly, hence the rubber mallet. Not a big deal, IMO.
The Renegades/Vipers are more forgiving of less than perfect fit, they are actually designed to fit a bit loose compared to the Glove.
The Epics are probably the most tolerant of poor fit, since you tighten them down with the cable system. I've successfully used a size too big on a horse and just shortened the cables. However, some people think the cables are hard to put on and take off. I don't think they're bad at all, though I do have to use a hoof pick to get them off (and I stomp the buckle down with my boot to get them on). I used the Epics initially after pulling shoes while the hooves were transitioning and changing size/shape. I still have them as spares if needed, and I use them to medicate hooves.
