For shipping use shipping boots.
And if you don't know how to wrap a horse's legs (like with polo wraps), don't wrap them. Wrapping incorrectly can do way more harm to your horse's legs than good, so you should only wrap them if you're absolutely certain you can do it right, which also means being physically taught by someone who can do it right.
I personally don't know too much about using wraps since I don't use them and surely never will, but I'd imagine you'd just purchase polo wraps. Someone please correct me if I'm wrong.
But again, don't wrap unless you've been taught correctly how to do it.
