Your walking shoes and trainers might be comfortable – but they could be made in a way that’s bad for the planet.
That’s why people are wearing Trees on their feet. No seriously. Here’s why you should make the switch to Allbirds' eco-friendly footwear.
Sorry, your shoes are (probably) bad for the planet
Here are four reasons why your shoes probably aren't sustainably made:
- They're made from raw or synthetic materials (such as rubber and plastic).
- Toxic glues are used to piece them together.
- The manufacturing process is energy intensive.
- They're part of an unregulated supply chain.

Why should you wear shoes made of Trees instead?
Sourced from something good
Allbirds’ Tree fibre (Tencel Lyocell) is mainly sourced from South African wood – and it’s FSC (Forest Stewardship Council) certified.
Halve your carbon footprint
Compared to materials like cotton, Tree uses 95% less water and cuts the carbon footprint by half.
Let your feet breathe
Allbirds’ Tree collection feature a Tree Fibre Blend. It’s breathable and wraps your feet in an airy hug.
Easy to clean
It’s durable enough to survive the washing machine, for easy cleaning.
What Tree-based trainers should I get?
These are bestsellers for a reason – here are our top picks from the Allbirds Tree collection.

We like this pair for its sock-like Tree upper that keeps your feet cool and dry when the temperature rockets.
Its sugarcane-based SuperLight Midsole ensures plush cushioning for all-day wear.
Tree Runner

Allbirds' most recognisable design. Versatility for any occasion – it's a classic for a reason.
It features a breathable eucalyptus fibre and a SweetFoam midsole for everyday comfort.
Tree Dasher 2

An active shoe for the sporty look, with a responsive foam and extra grip, making it versatile enough for light workouts as well as walks.
