LOVE EasyBoots. Have used them for 15+ years. Each style of boot fits differently so really need to measure your horse’s feet and use the guide to figure out the right size. My horses are always barefoot, so use easy boots to ride in and for sore feet. Have everything from original easy boot with keeper straps up to gloves. If you want use pads, buy boot a little bigger since pad does take up some room. Might want to contact Easy Care directly and ask for their assistance about sizing and then buy from Valley Vet – always good pricing. Good luck!
