Heel Wedge Inserts for Achilles Tendonitis

Learn how a simple heel lift can reduce Achilles tendon strain, ease morning pain, and support your recovery. This complete guide explains what heel wedges do, how to choose the right height, and when they are worth adding to your shoes.

Quick Answer: Heel wedge inserts for Achilles tendonitis work by slightly elevating the heel, which reduces the stretch and load on the Achilles tendon. Most people start with a 6–12 mm lift, worn in both shoes, and gradually reduce the height as symptoms improve. They are a temporary support tool, not a permanent fix — pairing them with stretching and strengthening is essential for full recovery.

🔑 Key Takeaways

Heel wedges reduce tension on the Achilles tendon by placing the foot in a slightly plantarflexed (toe-down) position.
Most guidelines recommend starting with a 6–12 mm heel lift, worn in both shoes to keep your gait balanced.
They are most effective during the acute and early rehabilitation phases, not as a permanent solution.
Heel wedges should be combined with eccentric strengthening, calf stretching, and load management for the best results.
Choosing the right insert depends on shoe type, lift height, material, and whether you need a full-length or heel-only design.

What Is Achilles Tendonitis?

Achilles tendonitis is an overuse injury that causes inflammation, pain, and stiffness in the Achilles tendon — the thick band of tissue connecting your calf muscles to your heel bone. It commonly affects runners, walkers, and anyone who spends long hours on their feet, especially when there is a sudden increase in activity or a change in footwear. The pain is often worst in the morning or after periods of rest, and it typically improves slightly with gentle movement.

Because the Achilles tendon bears enormous loads during walking, running, and jumping, even a small amount of irritation can disrupt your daily routine. If you are dealing with related foot pain such as plantar fasciitis, you may also find our guide on insoles for arch support and plantar fasciitis helpful, as many people experience both conditions together.

How Do Heel Wedge Inserts Help Achilles Tendonitis?

A heel wedge insert — sometimes called a heel lift, heel raise, or Achilles wedge — is a shaped insole or insert that elevates the back of the foot. By raising the heel by just a few millimeters, the ankle sits in a slightly plantarflexed position, which shortens the distance the Achilles tendon needs to stretch. This reduces tensile load on the tendon during walking and standing, giving the injured tissue a chance to calm down and heal.

In clinical practice, heel lifts are often recommended as part of a broader treatment plan that may include physical therapy, eccentric exercises, and activity modification. They are particularly useful for people who cannot fully rest from walking or working, and they can make everyday movement noticeably more comfortable during the recovery period.

Key Benefits of Heel Wedge Inserts

🦶 Reduced Tendon Strain

Elevating the heel decreases the stretch placed on the Achilles tendon with each step, which can significantly reduce pain during walking and standing.

🌅 Eases Morning Stiffness

Many people with Achilles tendonitis experience severe stiffness with their first steps of the day. A heel wedge worn in supportive footwear can make those first movements less painful.

🏃 Supports Return to Activity

During rehabilitation, heel lifts allow you to stay somewhat active while the tendon heals, rather than being forced into complete rest.

⚖️ Offloads the Calf Complex

By slightly shortening the calf-Achilles unit, heel wedges reduce the workload on the gastrocnemius and soleus muscles during daily activities.

👟 Fits Most Shoes

Heel-only wedges are slim and can be slipped into most closed shoes, including work shoes, sneakers, and casual footwear, without major fit issues.

💰 Affordable Support

Compared with custom orthotics, heel wedge inserts are a low-cost option that you can adjust or replace as your symptoms change. Quality options typically range from $15–$40.

Who Should Consider Heel Wedges for Achilles Pain?

Heel wedge inserts are generally considered for people who have been diagnosed with Achilles tendonitis or who are experiencing classic symptoms such as:

Pain and stiffness at the back of the heel, especially in the morning
Tenderness when squeezing the Achilles tendon
Discomfort that worsens with activity and improves with rest
Swelling or thickening of the tendon
Pain that limits walking, running, or climbing stairs

They may also be helpful for people recovering from Achilles tendon surgery or those with insertional Achilles issues. However, if your pain is severe, persistent, or accompanied by sudden weakness, you should see a healthcare professional before relying on self-treatment. For related foot and ankle support needs, you might also explore orthopedic shoes for Achilles tendonitis and shoes with arch support and heel cushions.

Types of Heel Wedge Inserts: Which One Is Right for You?

Not all heel wedges are the same. The best choice depends on your shoe type, the amount of lift you need, and how long you plan to wear them. The table below compares the most common options.

Type	Typical Lift Height	Best For	Material
Heel-Only Wedge	6–12 mm	Most closed shoes; temporary Achilles offloading	EVA foam, gel, silicone
Full-Length Insole with Heel Raise	6–15 mm	People who also need arch support or cushioning	PU, EVA, gel, memory foam
Adjustable Stackable Lift	3–15 mm (layered)	Gradual weaning as symptoms improve	EVA, foam, cork
Rigid Wedge (Cork/Plastic)	6–12 mm	Long-term use in structured shoes	Cork, hard plastic
Gel Heel Cup with Lift	4–10 mm	Additional shock absorption and comfort	Gel, silicone
Custom-Molded Wedge	Prescribed	Complex cases, significant deformity	Custom materials

For most people with mild to moderate Achilles tendonitis, a simple 6–10 mm heel-only wedge made from EVA foam or gel is a good starting point. If you also need arch support, a full-length insole with a built-in heel raise may be more appropriate. If you are unsure about the level of support you need, our guide on podiatrist-recommended shoes for flat feet can help you understand how foot mechanics influence footwear choices.

How to Choose the Right Heel Wedge Height

Choosing the correct lift height is one of the most important decisions. Too little lift may not provide enough relief, while too much lift can alter your gait excessively and cause new problems in the knee, hip, or lower back.

Start with 6–10 mm Most clinicians recommend beginning with a lift of about 6–10 mm (roughly ¼ to ⅜ inch). This is often enough to reduce tendon strain without dramatically changing your walking pattern.
Wear lifts in both shoes Even if only one Achilles is painful, wearing a heel wedge in both shoes helps maintain balance and prevents a leg-length discrepancy that could lead to other issues.
Gradually increase if needed If symptoms persist and your healthcare provider agrees, you can increase the lift in small increments — typically up to 12–15 mm. Avoid going higher without professional guidance.
Wean down as you improve As your tendon heals and strengthens, gradually reduce the lift height. This prevents your calf muscles from adapting to a permanently shortened position.
Match the insert to your shoe Heel-only wedges work best in shoes with a removable insole or enough depth in the heel. Full-length insoles are better for shoes with thin, flat footbeds.

⚠️ Important: Do not use heel wedges as a standalone cure. They are a supportive tool that works best alongside a rehabilitation program. If your pain worsens or does not improve within a few weeks, consult a podiatrist, physical therapist, or orthopedic specialist.

Pros and Cons of Heel Wedge Inserts

✅ Advantages

Simple, non-invasive way to reduce Achilles tendon load
Affordable and widely available without a prescription
Can be used in many types of closed footwear
Helps manage pain during daily activities and work
Adjustable and reversible as symptoms change
Useful during rehabilitation to maintain some activity

❌ Limitations

Does not address the underlying cause of tendonitis
Can feel awkward or alter gait if too high

Requires consistent use to be effective
Not a substitute for strengthening and stretching
Prolonged use without weaning can lead to calf tightness

How to Use Heel Wedges Correctly

Getting the most out of your heel wedge inserts means using them consistently and correctly. Here are practical tips:

Place them under the existing insole if possible, so they stay in position and do not slide around.
Use them in both shoes to keep your pelvis and spine balanced during walking.
Wear them during weight-bearing activities — especially walking, standing, and any exercise that does not aggravate the tendon.
Check the fit — the wedge should sit securely at the heel without bunching or creating pressure points.
Combine with eccentric heel drops and calf stretching, which are cornerstone exercises for Achilles rehabilitation.
Replace them when worn — compressed or flattened wedges lose their effectiveness over time.

If you also experience heel pain from plantar fasciitis, our article on memory foam insoles for plantar fasciitis discusses how cushioning materials can complement heel lifts. For those who need extra support while standing for long periods, most supportive shoes for standing all day offers additional footwear guidance.

Complementary Treatments for Achilles Tendonitis

Heel wedges are just one piece of the recovery puzzle. The most effective Achilles tendonitis treatment plans typically include:

🏋️ Eccentric Strengthening

Slow, controlled heel drops — both straight-knee and bent-knee — are widely recommended to rebuild tendon strength and resilience.

🧘 Calf Stretching

Gentle stretching of the gastrocnemius and soleus helps restore flexibility and reduce tension on the tendon.

🧊 Ice and Rest

Applying ice after activity and scheduling adequate rest can help manage inflammation during flare-ups.

👟 Supportive Footwear

Shoes with cushioned heels, good arch support, and a slight heel-to-toe drop can reduce daily strain on the tendon.

🩹 Orthotics and Insoles

Custom or over-the-counter insoles can correct biomechanical issues that contribute to Achilles overload.

💪 Load Management

Avoid sudden increases in training volume or intensity, and cross-train with low-impact activities while healing.

When to See a Healthcare Professional

While heel wedges can be a helpful self-care tool, some situations require professional evaluation. Seek medical advice if you experience:

Sudden, severe pain or a “pop” in the back of the ankle
Inability to bear weight or push off with the affected foot
Visible swelling, bruising, or deformity
Pain that persists for more than a few weeks despite rest and inserts
Numbness, tingling, or weakness in the foot or ankle

These symptoms may indicate a more serious condition such as a partial or complete tendon rupture, which requires prompt medical attention.

Frequently Asked Questions

How high should a heel wedge be for Achilles tendonitis? +

Most healthcare professionals recommend starting with a 6–12 mm heel lift. A common approach is to begin at 6–10 mm and increase gradually only if needed. Wearing the wedge in both shoes is important for balance. The goal is to reduce tendon strain without causing excessive gait changes.

Should I wear a heel wedge in both shoes or just the affected one? +

You should wear a heel wedge in both shoes, even if only one Achilles tendon is painful. Using a lift in only one shoe creates a leg-length difference that can lead to hip, knee, or lower back problems. Keeping both sides level helps maintain a balanced gait.

Are heel wedges a permanent solution for Achilles tendonitis? +

No. Heel wedges are a temporary support tool, most useful during the acute and early rehabilitation phases. Long-term use without weaning can lead to calf muscle tightness and dependence. The goal is to use them while you strengthen the tendon and gradually reduce the lift as symptoms improve.

Can I use heel wedges in any type of shoe? +

Heel-only wedges fit best in closed shoes with a removable insole or enough heel depth, such as sneakers, work shoes, and casual lace-ups. They may be difficult to fit into very shallow dress shoes or sandals. Full-length insoles with a built-in heel raise can be a better option for certain footwear styles.

Do heel wedges help with insertional Achilles tendonitis? +

Heel wedges can help with insertional Achilles tendonitis by reducing tension at the point where the tendon attaches to the heel bone. However, if the wedge presses directly on the inflamed insertion site, it may cause discomfort. In such cases, a wedge that lifts the heel without direct pressure on the tender area — or a heel cup with a cut-out — may be more appropriate.

What exercises should I do alongside using heel wedges? +

Eccentric heel drops are considered the gold standard for Achilles rehabilitation. Other helpful exercises include calf stretches (both straight-knee and bent-knee), toe raises, and balance training. Always consult a physical therapist for a personalized program, especially if your symptoms are significant.
