Heel lifts are wedge-shaped inserts placed in shoes to correct leg length discrepancies and improve posture and gait. Made of firm, waterproof materials, some models can be adjusted to different heights. Improper use can worsen musculoskeletal problems, so they should only be worn with a doctor’s recommendation.
A heel lift is a wedge-shaped insert that is placed into the back of a shoe, most often to correct a leg length discrepancy. It is generally made with a fairly solid and waterproof material and some models can be adjusted to different heights. Prolonged use of a heel lift can correct posture and gait irregularities, in turn relieving pain often associated with structural imbalances in the lower body. However, it can aggravate musculoskeletal problems if used improperly and therefore should only be worn with a doctor’s recommendation.
In general, heel lifts are made from a fairly firm and waterproof material such as rubber. This firmness provides a consistent lift height, which cannot be achieved with the foam-like materials typically used to make other types of shoe inserts. When viewed from the side, a heel lift is usually wedge-shaped, with the thickest point at the back. The back of a heel lifter is rounded so that when slipped into a shoe, it fits snugly against the heel.
Lifts are most commonly used for correcting a leg length discrepancy. This discrepancy may be due to a length variation in the leg bones or it may result from other musculoskeletal problems, such as a pelvic deformity or scoliosis. Usually, the body naturally adjusts posture and walking to compensate for these structural irregularities. The resulting abnormal stance and gait can cause ongoing discomfort or pain in the feet, ankles, legs, hips, buttocks, and back. In addition to this physical pain, those with uneven posture or an unusual walk sometimes suffer from a negative self-image.
Putting a heel lift in your shoe equalizes leg length. For many, this equalization instantly corrects posture and gait abnormalities. With extended use, a heel lift can also reduce or even eliminate the discomfort and pain associated with leg length discrepancies.
Some heel lift models feature an adjustable height. These elevators can be adjusted to range from approximately 0.13 inches (0.32 centimeters) to 1 inch (2.54 centimeters) in height. Leg length discrepancies that exceed a difference of 1 inch (2.54) may not be correctable with a heel lift. Those with significant length discrepancies may benefit from corrective surgery.
It should be noted that improper use of heel lifts can actually aggravate musculoskeletal problems. Therefore, they should not be worn without first seeking the advice of a doctor. If a heel lift is recommended, your doctor will usually take measurements to determine what height of a lift is needed.
