I personally use Professional's Choice SMB 3 boots on all four legs and then ballistic overreach bell boots on the front feet. My horse gets booted up anytime we are working on the patterns and when we compete.
The brand of boots, you will find, will vary widely from person to person because brand is really a matter of personal preference. Like as an example here, SorrelHorse likes her Classic Equine brand. While I like the Professional's Choice brand. Both brands are good brands; it's just personal preference.
Some people will also use polo wraps, which will basically work just as good as a sport boot. However, if you do not know how to correctly wrap polo wraps, then do not use them. You can physically damage the tendons/ligaments in a horse's leg by wrapping them incorrectly. So polo wraps can do MUCH more harm than good if you do not know what you are doing.
There's a lot of argument over whether boots support better than polos, or whether either one supports a horse's leg at all. I myself have actually read through the scientific studies. And it's not the 20-some-percent the companies claim their boots protect. However, sport boots do provide a little bit of support to the leg of the horse, and they do provide a little bit more support than a polo wrap. However, we are talking single digit percentages here, which really doesn't amount to much when we are involving a 1,000+ pound animal.
So I do not use sport boots on my horses for the purpose of support. I use them for the purpose of having something covering their legs. I feel like if I am asking them to perform quick advanced maneuvars at tremendous speed, that I should provide them with some protection that **might** help prevent injury.
Everyone will have their own personal prefernce, but my horses will always have sport boots on all 4 legs and bell boots on the front.
I know we aint in the 50s anymore but I don't remember seeing a horses legs wrapped untill the 80s for barrel racing? I do think they give a little support and keep a horse from cutting themself up in the legs but don't guarantee
a horse wont get injured either-- if a horse messes up they can still get a broke leg and can still stretch their tendons and ligaments wearing boots.. and that's why you work on making their legs stronger building muscle in their legs and condition them proper- boots aint an instant fix for that
and the horses I've run were up to par not lucky.
Who ever said they guarantee your horse won't get hurt if they wear sport boots?
And who said boots are a replacement for having your horse properly conditioned to run barrels?
No one is saying that.
Nothing can replace having your horse in good physical condition and fit to run barrels. And no, boots aren't going to prevent all injuries. But I've had several occasions where a horse hit themselves and tore off a chunk of the neoprene from the boot. I'd much rather the boot get damaged than my horse's leg. A sport boot is easy to replace and buy another. Missing flesh? Not so much. So that's why I boot up.
