Heel lifts are commonly used in clinical practice to manage foot and ankle pain, particularly conditions affecting the plantar heel and Achilles tendon, but the evidence base is mixed and often low quality. They appear to offer short‑term pain relief and functional improvement in selected patients, while their long‑term efficacy and ideal prescription parameters remain uncertain.
Rationale and proposed mechanisms
Heel lifts elevate the calcaneus relative to the forefoot, effectively plantarflexing the ankle and altering load distribution through the foot and lower limb. By reducing peak ankle dorsiflexion and shortening the gastrocnemius–Achilles complex, heel lifts are thought to decrease tensile and compressive loads on painful tissues such as the plantar fascia and Achilles tendon insertion. Biomechanical studies in asymptomatic individuals demonstrate that heel lifts of 10–18 mm can reduce maximum ankle dorsiflexion angle, shorten gastrocnemius–tendon unit length during running, and modify muscle activation patterns, supporting a mechanical basis for symptom change. In addition, elevating the heel can redistribute plantar pressures away from the posterior calcaneus, which may be particularly relevant in plantar heel pain and calcaneal spur–related discomfort.
Evidence in plantar heel pain
Several clinical and quasi‑experimental studies have evaluated heel elevation or heel lifts in plantar heel pain, though most are small and at high risk of bias. A systematic review of heel lifts for lower limb musculoskeletal conditions found very low‑certainty evidence from a single trial (n = 62) that heel lifts improved pain and function more than indomethacin at 12 months in plantar heel pain, as measured by the Foot Function Index. Another trial in calcaneal apophysitis suggested that custom orthoses were superior to simple heel lifts for pain relief at 12 weeks, indicating that a heel lift alone may be less effective than more comprehensive orthotic interventions in some paediatric presentations. Outside formal trials, a small study of patients with radiographic heel spurs showed that increasing shoe heel height reduced plantar heel pain in most individuals over eight weeks, with optimal relief at heel heights of 3–4 cm, presumably by lowering plantar forces under the calcaneus.
These findings suggest that heel lifts can reduce plantar heel pain for some patients, but they also highlight heterogeneity in response and the importance of individual foot morphology. For example, work by Kogler and colleagues (summarised in a narrative review) indicates that arch configuration may influence how heel elevation affects plantar fascia strain, implying that some arch types may benefit more from this strategy than others. Clinically, this supports using heel lifts as part of a broader management plan that may include stretching, load management, strengthening, and, where indicated, custom foot orthoses, rather than as a stand‑alone cure.
Use in Achilles tendinopathy
Heel lifts are widely advocated in Achilles tendinopathy due to their capacity to reduce dorsiflexion range and potentially decrease tendon loading during walking and running. A systematic review of heel lifts reported low‑ to moderate‑certainty evidence that, in at least one trial of mid‑portion Achilles tendinopathy, heel lifts were superior to eccentric calf exercise alone in reducing pain severity and improving VISA‑A scores at 12 weeks, with similar rates of minor adverse events such as new areas of musculoskeletal pain or blisters. More recent work in insertional Achilles tendinopathy has reinforced this potential benefit: a prospective study showed immediate reduction in pain during gait and improvement in symptom severity after two weeks of using in‑shoe heel lifts, along with positive changes in gait parameters such as walking speed and stride length. Biomechanically, these effects may relate to increased distance between the tendon and calcaneus in static stance and altered stance‑phase sub‑phase timing, including increased load response and decreased preswing duration.
Randomised feasibility work, such as the LIFTIT trial for insertional Achilles tendinopathy, indicates that a fully powered trial comparing heel lifts with sham devices is feasible and that preliminary data “signal” improvements in pain, function, physical activity, and quality of life with heel lifts. However, these pilot studies are not powered to definitively establish efficacy, and planned large‑scale trials like the LIFT trial for mid‑portion Achilles tendinopathy are still underway or recently initiated. Thus, while clinical and early trial evidence support the short‑term use of heel lifts as part of conservative care for Achilles tendinopathy, there is still uncertainty about optimal lift height, duration of use, and comparative effectiveness against other evidence‑based treatments such as heavy–slow resistance programs.
Broader biomechanical and clinical considerations
Beyond plantar heel pain and Achilles tendinopathy, heel lifts can influence global lower limb biomechanics, which has potential benefits and risks. Studies have shown that heel elevation during walking, running, or squatting can reduce ankle dorsiflexion demands, increase ankle work contribution, and modify activation of key muscles including the gastrocnemius, vastus lateralis, biceps femoris, and tibialis anterior. These changes may help clinicians offload painful structures, facilitate certain rehabilitation exercises, or accommodate limited ankle dorsiflexion in patients with equinus or post‑surgical stiffness. On the other hand, narrative reviews caution that higher heel elevations—whether via lifts or high‑heeled footwear—can alter gait patterns, increase fall and inversion sprain risk, and shift plantar pressure to the forefoot, potentially provoking new symptoms in the forefoot, knee, hip, or lumbar spine.
In addition, heel lifts may trigger neuromuscular responses that increase calf muscle activity, which is not uniformly beneficial; in some individuals this might aggravate posterior chain symptoms rather than relieve them. Adverse events reported in trials include development of new pain in the lower back, hips, knees, feet, or ankles, as well as skin irritation and blisters, although overall rates appear similar to comparison interventions. These findings underline the importance of careful patient selection, gradual introduction, and close monitoring when using heel lifts, particularly in individuals with complex multi‑site pain or balance impairments.
Clinical application and future directions
In practice, heel lifts are best viewed as a supportive adjunct rather than a definitive treatment for foot pain. For plantar heel pain, a modest, removable heel lift can be trialled alongside education, activity modification, plantar fascia–focused strengthening, and calf stretching, with close attention to changes in pain, function, and plantar pressure distribution. For mid‑portion and insertional Achilles tendinopathy, heel lifts may be particularly useful in the early, irritable phase to reduce pain during gait and exercise, potentially improving adherence to progressive loading programs. Clinicians should individualise lift height, usually starting with small increments (for example 6–10 mm) and adjusting based on symptom response and gait observation, while monitoring for secondary issues such as forefoot overload.
From a research perspective, the current literature is characterised by small samples, heterogeneous protocols, and low‑certainty evidence, despite promising signals of benefit in specific conditions. Ongoing and future randomised controlled trials comparing heel lifts with sham devices, custom orthoses, and established exercise programs will be critical to defining their true clinical value, cost‑effectiveness, and ideal prescription parameters. Until then, heel lifts should be prescribed judiciously, with clear expectations communicated to patients that they are one component of a multimodal strategy aimed at reducing pain, optimising load, and facilitating return to function rather than a stand‑alone cure.
