How to know what size splint boots to get your horse?
I use classic equine Legacy system boots and I was wondering if there was a proper way to size them? I know some of the other boot brands have a size chart, but I only use the legacy boots. I am buying boots for my new horse and new boots for my horse i’ve had, and I wanted to be sure to get the right sizes. Also what is too tight as far as putting the boots on and what is too loose? thanks!
When I’m shopping for boots for my horse, I usually refer to a size chart, becuase most boots come with them, but they are based mostly on the horse’s height and or weight. If your horse is funny shaped like mine, then it can be a bit of a pain. What I do is I’ll get boots that are supposed to fit my horse, and if they dont, I return them immediately. To make sure they fit, I look at several things: As far as how high they go on the horse’s leg, they should go almost all they way up to the back of the knee on the front legs, and on the back legs, I like them cover the tendon fully (if they’re that kind, which yours look like they are), so about 1-3 inches below the hock, depending on your horse’s legs. With your boots, you should make sure that they cover the fetlock completely, making sure that it is snug (you should be able to feel it, make sure that it doesnt wiggle and that theres no empty spaces. You should also be able to get your finger up in there, and feel that it is snug. if it feels like its cutting your horse’s circulation off, then it probably is.) With the rest of the boot covering the cannon bone, you again, want to make sure that it is pretty snug, for a loose boot offers no support at all. I like to make sure that I can fit a finger or two in the top of the boot, and just barely wiggle it around, that way I know that its snug, but not too tight. If you can slide your fingers in without a bit of resistance, then its probably too loose. Most of the time, boot buying is just a guess and check kind of experience, so hopefully I was able to help and make this experience less traumatic!
