Heel Lift versus Full Sole Insert: What’s the Difference?


When one leg is shorter than the other, it’s called a leg length discrepancy.

It’s estimated that between 40% and 70% of the population has unequal leg lengths. While it can often be barely, if at all, perceptible to the naked eye, even a slight discrepancy can cause frustrating aches and pains.

Both the Adjust-A-Lift Heel Lift and the Full Sole Insert can treat this leg length problem, so how do you choose?

What is the Adjust-A-Lift Heel Lift?

The Adjust-A-Lift® Heel Lift is a product that is inserted in the back of a shoe to lift the heel. This small lift can even out the length inequality between legs and help resolve related pain. It can also be useful in treating foot and ankle conditions like plantar fasciitis, heel spurs and Achilles’ tendonitis. The heel is made with three layers of extra firm, open cell foam rubber, each 1/8-inch-thick, held together with double-sided adhesive. Layers can be removed to accommodate the height the user requires.

Use: Treat the low back pain, hip pain, and knee pain related to a leg length discrepancy.

What is the Full Sole Insert?

The  Full Sole Insert is placed on the insole of the shoe to slightly raise the foot within. Like the heel lift, it’s a treatment method for leg length differences, but it raises the whole foot rather than just the heel. Some people prefer a whole foot lift instead of a heel lift to fix leg length problems. But when used as a pair, it can also address a host of other comfort issues. It can help prevent foot disorders from forming, extend the life of your shoes, help a large shoe to fit more snugly, and make your feet more flexible and safe.

Use: Treat pain related to leg length discrepancy and increase general foot comfort while wearing shoes.

Which is better?

Both! It depends on the person and the problem. When used to address leg length differences, it’s a matter of preference. Some people feel a heel lift is more comfortable but others prefer the full sole. If you have a leg length discrepancy, talk to your doctor and give both the Adjust-A-Lift® Heel Lift and the Full Sole Insert a try.
