Shoe lifts, also known as heel lifts or shoe inserts, are small inserts that can be placed inside a shoe to add height to the heel.
Shoe lifts can be healthy and helpful for many people, but it depends on why they’re being used, how high they are, and how they’re fitted. In general, a properly sized lift can reduce strain on the body by helping the hips and spine stay more level, especially for people with a leg length difference (LLD). When the body is uneven, it often compensates by tilting the pelvis, shifting the spine, or overworking one hip. Over time, that can lead to discomfort in the lower back, hip, knee, or even the ankle. A lift can help reduce those compensations and make walking feel smoother and more balanced.
That said, shoe lifts are not “one size fits all.” If the lift is too high, too stiff, or placed incorrectly, it can create new issues. A thick in-shoe lift can crowd the foot and change how the heel sits in the shoe, which may lead to rubbing, heel slipping, or pressure on the toes. Some people also feel calf tightness when they start wearing lifts because the heel sits higher than usual, similar to wearing a shoe with a higher heel. This isn’t always dangerous, but it’s a sign the body is adjusting and the lift might need to be introduced gradually.
A good rule is that small lifts are usually easier on the body, and higher lifts require more planning. Many people do well with a low in-shoe lift, but once the lift gets higher, it may feel unstable or make the shoe too tight. That’s when an external lift (built onto the bottom of the shoe) is often healthier and more comfortable, because it adds height without cramming the foot upward inside the shoe. External lifts can also be built to keep the shoe level and stable, which helps the gait feel more natural.
If the main goal is comfort and long-term body balance, shoe lifts are healthiest when they are:
- Based on a real need (like LLD or posture/gait issues)
- The correct height (not guessed too high)
- Gradually introduced if they’re noticeable in height
- Used with supportive shoes (not worn in flimsy footwear)
- Adjusted if pain, rubbing, or instability happens
