I’ve worked with many people who describe the same frustrating cycle: a respectable recovery after rest or rehab, then a stubborn recurrence of Achilles pain as soon as life gets busy again. One simple, evidence-informed tool I often test with clients is a targeted heel lift. It’s not a cure-all, but used thoughtfully it can reduce strain on the Achilles while you rebuild capacity. Below I’ll walk you through a practical, four-week at-home trial that lets you see if a heel lift helps your symptoms, how to implement it safely, and what to watch for.

Why a heel lift might help

The Achilles tendon transmits the powerful pull of your calf muscles to your heel. When that tendon is irritated or recovering from overload, reducing how far the calf has to stretch at each step can lower mechanical strain. A heel lift does this by slightly raising the heel relative to the forefoot, shortening the effective length of the calf–Achilles unit and decreasing peak tensile load during walking and running.

Research and clinical experience suggest heel lifts can provide symptom relief for mid- to long-term Achilles issues, especially when combined with a strengthening program and load management. However, lifts are generally best used as a temporary, supportive strategy—not an endless crutch. The goal is to reduce pain enough to allow progressive loading and return to normal mechanics.

Who should try this 4-week test

This test is appropriate if you have:

  • Recurrent or persistent mid-portion or insertional Achilles discomfort that flares with walking, running, or prolonged standing.
  • Symptoms that improve with rest but return with activity (i.e., load-sensitive pain).
  • No unexplained swelling, fever, or severe loss of strength or range that would suggest a more serious problem.

    • Don’t try this if you have been advised by a clinician to immobilize, have a recent complete tendon rupture, or have serious vascular or neurologic foot conditions. If you’re unsure, check with a health professional first.

    What you’ll need

  • A simple heel lift or stack of lifts (silicone, foam, or cork). You can buy discreet heel lifts from brands like Superfeet, Dr. Scholl’s, or smaller insole inserts from Amazon. Even a folded foam pad in a shoe can work for a test.
  • A pair of shoes you wear most often (walking shoes or trainers are best). Make sure there’s room for the lift without cramping the toes.
  • A notebook or phone to track symptoms and activities.

    • Baseline check (before week 1)

    Spend a few days without a lift and note:

  • Average pain during a typical walk or run (0–10 scale).
  • Morning stiffness or pain after inactivity.
  • How long it takes for pain to come on during activity and how quickly it settles afterwards.

    • Take photos or short videos of your shoes and gait if possible — they can be useful later to notice any mechanical changes.

    Four-week trial protocol

    Use the table below to guide week-by-week expectations. The lift height I usually trial is 4–8 mm for mid-portion Achilles issues; insertional Achilles problems may respond better to slightly less (3–5 mm) because too much lift can increase compression at the tendon insertion. Start on the lower end if you’re unsure.

    Week What to do Goals
    Week 1 Insert a 4 mm lift in your shoe for daily walking. Use only in your regular shoes. Track pain before/during/after activity. Keep normal activity but reduce high-intensity sessions if pain spikes. See immediate pain response and comfort with the lift; avoid overreliance.
    Week 2 If pain decreased, continue. Add gentle eccentric-concentric calf strengthening (see exercises below) 3× per week. If symptoms unchanged or worse, try 2 mm increase or swap to a different lift material. Begin progressive loading while monitoring symptom trend.
    Week 3 Increase walking duration or a low-intensity run by 10–20% if pain stays below baseline. Continue strength work and add mobility: ankle dorsiflexion stretches and plantarflexion control drills. Build tolerance without pain worsening beyond a mild, acceptable level (see “acceptable pain” below).
    Week 4 Start phasing out lift use for short periods—remove for easy walking at home or during warm-ups. Continue strengthening and progressively reintroduce normal shoe heel drop. Reassess baseline measures at the end of week. Determine whether the lift is a temporary aid or seems necessary long-term.

    Sample exercises to combine with lifts

    These are gentle, evidence-backed calf/achilles exercises. Do them on a flat surface unless otherwise noted.

  • Seated calf raises: 3 sets of 12–15, slow control. Good if pain is more provoked by standing.
  • Standing eccentric calf lowers: 3 sets of 15 per leg. Rise with both feet, lower with the affected foot slowly. Progress to single-leg once tolerated.
  • Ankle dorsiflexion mobility: kneeling half-kneeling ankle mobilizations, 2–3 sets of 10 slow repetitions.

    • Start with a pain-guided approach — some soreness with eccentric work is normal, but avoid sharp increases in baseline pain.

    How to interpret results

    Throughout the trial, use these rules of thumb:

  • Meaningful improvement: Consistent reduction in average pain level by 30% or more, easier activity tolerance, less morning stiffness. This suggests the lift is offloading important strain and can be used as a temporary aid while you continue strengthening.
  • No change: If pain is roughly the same, the lift may not be the right tool for your problem. You can still continue strength work, but consider a clinical review.
  • Worse symptoms: If pain increases substantially, you feel heaviness, numbness, or have sharp pain, stop using the lift and consult a clinician.

    • “Acceptable pain” during exercise is generally mild and settles within 24 hours. If pain is prolonged or progressively worse, that’s a red flag.

    Practical tips and common questions

  • Why not just always wear a lift? Long-term reliance can change calf length-tension relationships and foot mechanics. The aim is to use a lift to reduce pain while gradually restoring tendon capacity.
  • How tall should the lift be? Start small: 4 mm is a good first test. Only increase in small increments (1–2 mm). Some runners need 6–8 mm short-term, but big lifts can shift loading to other joints.
  • Should I put the lift in both shoes? Yes, for symmetry I usually recommend both shoes unless there’s a unilateral leg length discrepancy addressed by a clinician.
  • Material choice? Softer materials feel comfortable but compress over time; firmer inserts preserve height better. For a trial, cheap foam is fine; for longer use consider a quality silicone or cork insert.

    • When to get professional help

    If the trial doesn’t give clear benefit, pain worsens, or you have persistent weakness or swelling, seek assessment from a physiotherapist or podiatrist experienced with Achilles conditions. They can offer tailored orthotic solutions, a progressive loading plan, and address footwear or gait mechanics more specifically.

    I encourage you to approach this test with curiosity and careful tracking — a small change like a lightweight heel lift can sometimes be the missing piece that lets you build back strength without repeated flare-ups. If you try the four-week trial, jot down your experiences and I’m happy to help interpret your results or suggest next steps.
