With the Easyboots, you can buy pads to put in the bottom of the boot if you want something to cushion your horse's feet. My barefoot trimmer recommened the Easyboots over Cavallos as she said Cavallos tend to wear out quicker and don't have the longevity of the Easyboots, but having never tried them wouldn't know myself.
Check out the EasyCare website, they have lots of boots as well as the Epics... > Horse Care at EasyCare, Inc.: Horse Hoof Care, Natural Hoof Care, Hoof Care, Horses
With the bell boots, I've found a pair on eBay for $0.99, haha, so what the heck? I may as well try.
Thanks for the info on the other boots too. Muchly appreciated!!!
