A heel lift can be used to reduce stress on the Achilles tendon or lower leg structures, or to address equinus conditions, for example. In the case of an anatomical limb-length discrepancy, a heel lift may be applied under the device on the short side.
These lifts are placed at the back and center of the device, extending forward until finishing under the tarsal area. They are available in thicknesses of 4 mm, 6 mm, and 8 mm in small, medium, and large.
A combination of these lifts can be used to obtain higher thicknesses. However, it’s doubtful that a thickness of more than 8 mm could be used in most modern footwear.
