What is the primary function of a heel lift in orthotic devices?

The primary function of a heel lift in orthotic devices is to increase the height of the heel. This adjustment can provide several benefits, such as reducing the strain on the Achilles tendon for individuals with conditions like Achilles tendinitis or heel pain. By raising the heel, the heel lift can alter the angle of the foot and leg, which may help to alleviate discomfort and improve biomechanical alignment during activities like walking or standing.

A heel lift can also assist those with leg length discrepancies by compensating for a shorter leg, thus improving overall balance and reducing the risk of compensatory issues that might arise due to uneven leg lengths. This therapeutic tool effectively modifies lower limb dynamics, promoting better function and comfort for the patient.
