What are Heel Lifts?
Introduction
Heel lifts, also known as heel raises or shoe lifts, are versatile footwear devices designed to elevate the heel within the shoe. While primarily used to address leg length discrepancies and Achilles issues, heel lifts offer a range of benefits and can be utilized for various foot and lower limb conditions.
Benefits, Uses, and Considerations of Heel Lifts:
Correct Leg Length Discrepancies: Leg length inequalities, whether anatomical or functional, can lead to gait abnormalities, posture issues, and musculoskeletal imbalances. Heel lifts provide a simple and effective solution by compensating for the height differential between the legs, promoting better alignment and balance during walking and standing.
Reduce Load on the Achilles: Heel lifts can reduce tension and strain on the Achilles tendon by raising the heel and reducing the degree of ankle dorsiflexion. This elevation helps offload the Achilles tendon and may alleviate symptoms of Achilles problems, such as pain and stiffness, particularly during activities that involve repetitive ankle movement.
Reduce load on the Plantar Fascia: Heel lifts can be used as part of a comprehensive treatment plan for plantar fasciopathy, a common cause of heel pain. By slightly elevating the heel, heel lifts help reduce tension on the plantar fascia and alleviate pain associated with weight-bearing activities. When combined with exercises, orthotic support, and footwear modifications, heel lifts can contribute to the management of plantar fasciitis symptoms.
Enhance Comfort and Cushioning: Heel lifts often feature cushioning materials such as foam, gel, or silicone, which provide additional shock absorption and comfort for the heel and foot. This cushioning can help reduce impact forces during walking or running, making it easier to tolerate extended periods of standing or walking on hard surfaces.
Assist function and squatting: Heel lifts have been found to increase squat depth and can assist with some common causes of knee pain such as patellofemoral pain syndrome. This is because heel lifts can increase available ankle range of motion, one of the biggest contributors to squat depth. When ankle range is impacted, there may be increased loading or forces placed onto the knee or patella, this is the reason that weightlifting and squat shoes often feature substantial amounts of heel drop/pitch.
Varying Heights and Materials: Heel lifts come in varying heights and materials to accommodate different needs and preferences. Heights typically range from a few millimeters to several centimeters, allowing for customized elevation based on individual requirements. Materials such as polypropylene, 3D printed plastics, EVA foam, and TPU offer different levels of support, durability, and comfort.
Considerations for Optimal Use: While heel lifts can provide numerous benefits, it's essential to use them judiciously and avoid excessive elevation. Too much of a lift may alter gait mechanics, increase the risk of ankle instability, and exacerbate existing foot and lower limb issues. It's recommended to start with a conservative height and gradually adjust as needed under the guidance of a healthcare professional such as a podiatrist or physiotherapist.
Conclusion:
Heel lifts are versatile devices that offer numerous benefits for individuals with various foot and lower limb conditions. Whether used to correct leg length discrepancies, alleviate heel pain, improve posture, or enhance comfort, heel lifts can play a valuable role in promoting overall foot health and well-being. By understanding their benefits, uses, and considerations, individuals can make informed decisions about incorporating heel lifts into their footwear and orthotic regimen, leading to improved comfort, stability, and mobility
