Many horses brush (when the hoof grazes the opposite
fetlock/pastern/cannon) due to the way they move, or when
they become unbalanced, so it makes sense to protect your horses
valuable legs from injury. They can be used whilst warming up for a
big dressage comp (the white set look really smart!), training at
home on the arena, are brilliant for protection against bumps and
scratches whilst jumping, riding out, cross country training...they
are even great as a paddock boot!
