Splint boots: to prevent ankle knocking, and extra leg support and protection.
Bell boots: Basically the same as over reach-boots only without the ankle support....and just incase you don't know over-reach boots prevent a horse from tearing up the back side of the front ankles with their back feet due to over reaching with the back legs.
I know this cause I actually use both splint boots and over-reach boots...my friend uses bell boots lol Only her horse does over reach I just use mine for the extra leg protection and support. :)
Horses Will Listen...Even When No One Else Could Possibly Understand...
