If your horse is going to catch a shoe hard enough to FORCEABLY RIP that shoe off their foot, or even bend it, a bell boot is not going to stop it. They'll bend or rip off the shoe right through your bell boot.
Try to bend a shoe with your bare hands. You can't. So think of how much force that takes to do that.
Some farriers advocate horses should wear bell boots all the time to prevent pulling a shoe, but that logic doesn't make sense to me (or my farrier).

It is not enough to know how to ride; one must know how to fall.
