Sizing Guideline
To choose the right size, it is necessary to measure the circumference of the front cannon bone. Take a tape measure and wrap it around the middle of the cannon bone without tightening too much to take the measurement.
Circumference of Front Cannon Bone
Small
17 cm - 20 cm (6.5 to 9 inches)
Medium
20 cm - 23 cm (9 to 10 inches)
Large
Over 23 cm (over 10 inches)
If you are buying protection for the hind legs, the measurement is normally taken on the front limb. It is in fact very uncommon that between front and rear legs, there is such a difference to require boots of different sizes.
Many people think that the protection must cover the entire deep flexor tendon even up to the carpus (the knee). Not only the part of the tendon most exposed to trauma is the lowest, but a protection that is too high would just bother the tendon when flexing, particularly during the jump.
