No more noise: a step-by-step guide to diagnosing and fixing squeaks in your Allbirds Tree Glider shoes.
Quick answer
Most squeaks in Allbirds Tree Glider shoes come from moisture trapped between the insole and midsole, or from debris caught in the knit upper. Start by drying the shoes thoroughly before trying any other fix.
Why the midsole foam can amplify noise
The Tree Glider's midsole is made from SweetFoam™, a lightweight sugarcane-based foam. It's great for comfort and sustainability, but like many soft foams, it can amplify friction sounds rather than dampening them. This is normal and not a defect. Understanding the material helps narrow down the real cause.
When to accept a little noise vs. when to act
If the squeak only happens on certain floors (like polished concrete or tiles) and disappears on carpet, it's likely just the outsole gripping the floor—this is normal and will fade with wear. If the noise happens on every surface and doesn't change with the floor type, proceed with the diagnosis below.
Diagnosis: Find the cause of your Tree Glider squeak
- Symptom: A high-pitched squeak that occurs with every step, usually at the heel or midfoot, and on multiple floor types.
- Likely cause: Trapped moisture between the removable insole and the midsole, or a small piece of grit/debris under the insole. If the shoe is wet, moisture is the most likely cause.
- Corrective action: 1. Remove both insoles and let them air out separately for 12-24 hours. 2. Check the insole bed for debris and clean with a soft brush. 3. Reinsert the insoles and walk test. 4. If the noise persists, sprinkle a thin layer of cornstarch or baby powder under the insole to reduce friction (test on a small area first). Re-test after drying; most squeaks resolve at this stage.
- When to stop or choose another option: If the noise continues after these steps, it may involve the outsole or midsole foam itself. This is rare but possible. Contact Allbirds customer support for a warranty check; if needed, consider replacing the shoe rather than attempting further permanent modifications that could void the warranty. Do not use oils, sprays, or glues—they can damage the midsole foam.
