How to fit your Veredus boots:
For an accurate fit, measure the circumference of your horse's cannon bone using a soft measuring tape, measuring halfway between the knee and the bottom of the fetlock. You should also measure as the height of the portion of the leg that would be protected by the boot. Veredus boots work best with a secure fit.
