I guess it depends on what kind of hock boots you are refering to. :) The BOT and PHT hock boots are like "alternative therapy" where as plain neoprene hock boots can be used on a horse who gets sores on their hocks from getting up in their stall.
I use my BOT before I ride and run to help warm the joint up and PHT after to help with soreness!! I love my hock wraps and I like both products for there different reasons!
