My TB gelding has been wearing ScootBoots for four years now. I initially chose them because I really like that they don’t stay wet/damp (except for the neoprene gaiters, which are easy to change out) and don’t cover the coronet. We do a lot of trails, low-level dressage and a little jumping and they’ve held up well through all of it.
If you follow the sizing guidelines online, the company will guarantee fit. And, yes, they will also tell you if your horse’s feet are not a shape that will work with the boots.
I’ve only had one front strap break (at the screw hole) and I believe it was because the screws were so tight they were biting into the material. I don’t tighten mine to the point of no return, but do check them regularly and occasionally find one or another has loosened a bit. They’re a little awkward to tighten, but having a friend to help makes it easier.
I REALLY like the new mudstraps, especially because I can take out the rear screws that hold the older-style pastern straps on the boot. If my horse was going to show any sign of irritation after a particularly long ride, it was directly under those screws, so I’m glad to be rid of them.
I also use the SB pads, which are thin but seem to give just the right amount of extra protection when we hit the rare sharp-rocky patch of ground. (If you order pads, be aware you might need to go up a boot size.)
