To ensure you are using the proper size boots for your horse please take a measurement of your horse's canon bone midway between his fetlock and knee, exactly how it is being shown in the picture.

We recommend using a soft tape measure. If you do not have a soft tape measure you can use something like string, wrap it around the canon bone, mark where the end meets the rest of the string and then simply lay it flat next to a tape measure, ruler or yard stick to get your measurement.

SIZING CHART:

Small: up to 8.5 inches
Medium: 8.5 inches to 9.5 inches
Large:  9.5 inches and up

Sizing chart is good for both our Iconoclastâ„¢ Orthopedic Sport Boots as well as our Iconoclastâ„¢ Orthopedic/Rehabilitation Boots.
