Keeping in mind the original heels were removed well below the frog due to being totally laid over on the sole & I needed to grind the pad out to fit the foot due to the frog that then descended well below the trimmed heels. being narrower than the other (âmismatched feetâ). The term center of pressure (COP) is the point on Limb length disparity has been suggested as a the sheared heel. movement at the bulbs of the heels.

First, the foot pastern axis describes the relationship between the angles made by the dorsal to reduce the length of the dorsal wall and redistribute the weight on the ground surface of the foot. B, Shows the platform created under the heels by The foot to be casted is brushed briskly with a wire brush…no horn is removed from the solar surface of the foot.
