Two important measuring points for short limb build-ups are at the center of the heel and at the ball of the foot. The prescription should specify the leg length difference and the height of the elevation requested for the ball and heel. Elevations need not be cumbersome or heavy. Liquid to rigid foam materials create an attractive, light elevation.
METATARSAL BARS lose their effectiveness if applied to footwear that does not fit the foot properly. The first and fifth metatarsal heads are landmarks in positioning the various types of metatarsal bars. When applied, the metatarsal bars should not be placed pressure of any individual head.
