The MagnaCu Bell boots are great for maintaining a healthy hoof. The more circulation you can get to the hoof the healthier it will be and these do a great job at helping.
Magnetic bells boots are designed to help relieve symptoms of navicular, abscess, quarter cracks, etc.
These are to be used at rest.
Each bell boot contains 7 ceramic magnets strategically placed to give the hoof therapy where needed.
I have even seen it used on us, around our arm or leg.
