Trekker 4mm Heel Lifts – Self-Adhesive Heel Raises for Shoes
Trekker 4mm Heel Lifts are firm, self-adhesive heel raises designed to sit inside footwear or beneath orthotics. A 4mm lift is the thinnest option in the Trekker range — ideal when you need a subtle height increase to address a mild leg length discrepancy, reduce strain on the Achilles tendon, or take pressure off the forefoot.
The firm EVA construction holds its shape under body weight without compressing flat, and the peel-and-stick adhesive keeps the lift securely in place inside the shoe. Sold in packs of 5 pairs.
Key Features
- 4mm lift height — the thinnest Trekker option for subtle correction
- Firm EVA construction — maintains height without compressing under load
- Self-adhesive backing — peel and stick for a secure fit inside the shoe
- Works with orthotics — fits underneath custom and prefabricated orthotics
- Trimmable — can be cut to fit different shoe sizes
- Sold as 5 pairs — enough to set up multiple pairs of shoes
Which Height Do I Need? 4mm vs 6mm vs 8mm
The right height depends on what you're correcting. A 4mm lift suits mild leg length differences (under 5mm), early Achilles tendinopathy where a small lift reduces tendon strain, or situations where shoe volume is tight. A 6mm lift is the most commonly prescribed height for moderate leg length discrepancy and general Achilles offloading. An 8mm lift provides the maximum correction for larger discrepancies — though lifts above 8mm typically require a shoe modification rather than an in-shoe insert. Your podiatrist can advise on the correct height for your situation.

Frequently Asked Questions
What are heel lifts used for?
Heel lifts (also called heel raises) are used to correct leg length discrepancy, reduce strain on the Achilles tendon, offload the forefoot, and manage conditions like Sever's disease in children. They raise the heel inside the shoe to adjust lower limb biomechanics.
Can I use heel lifts with orthotics?
Yes — Trekker heel lifts are designed to sit underneath orthotics inside the shoe. The adhesive backing keeps them in place beneath the orthotic shell.
Will a 4mm heel lift fit in my shoes?
4mm is thin enough to fit in most shoes without making them feel too tight. If your footwear is already snug, the 4mm is the safest starting point.
How long do they last?
Each pair typically lasts 3–6 months with daily wear, depending on body weight and activity level. The pack of 5 pairs gives you enough for multiple shoes and replacements.
Do I put heel lifts in both shoes?
That depends on why you're using them. For leg length discrepancy, the lift usually goes in the shoe on the shorter side only. For Achilles tendon issues, bilateral lifts (both shoes) are common. Follow your podiatrist's recommendation.
