Sustainable trainers: 8 best to invest in for a more eco-friendly wardrobe

First things first - Veja is a certified B Corp, which means the brand is genuinely doing its bit for both people and planet. The Impala shoes are one of the first workout offerings from the brand, and they're great. Made from organic, agroecological, and fairtrade cotton, wild rubber from the Amazonian Forest, and innovative materials, such as recycled plastic bottles, you can't go far wrong.

Another B Corp trainer brand is Allbirds. One of their best selling trainers is the Tree Dasher 2, a carbon neutral shoe made from responsibly sourced eucalyptus tree fibre. Fun fact: even the shoe laces are sustainable, as they're made from recycled plastic bottles, as is the foam insole, crafted from castor beans. Some of their trainers use as much as 60% less energy than materials used in your typical synthetic shoes.

Another great sustainable trainer from Allbirds is the Tree Flyer, their latest edition to the family. They're the lowest CO2 shoe in the world at current, with a carbon footprint of 8.09 kg CO2e. We particularly like the merino wool heel lining and how springy they are to run in, but read our full Allbirds Tree Flyer review, here. 

As part of adidas’ journey to End Plastic Waste and help reduce the use of virgin plastic, this next generation of more sustainable Stan Smith’s takes the iconic silhouette and propels the franchise firmly into the future. The sneaker features a white PRIMEGREEN upper, a series of high-performance recycled materials, matched with a recycled rubber outsole.

The Origin features an interesting and considered design that only uses five pieces to make up the final product, reducing its carbon footprint and using zero glue in the process. Clarks have incorporated mono-materials, recycled materials from production waste and recyclable materials throughout, even the laces are made from 100% recycled polyester.

Po-Zu uses organic cotton and natural linen in its shoes and only uses leather in small quantities and chromium-free. It uses solvent free leather alternatives, working with materials like Eco Micro Fibre, Frumat Appleskin and Piñatex, all great hard wearing and 100% vegan.

From recycling scrap material with a 0% wasted material policy, local production, 0% oil use, 100% use of renewable resources and 90% recycled water in the production process, Giesswein has a huge Green Strategy company policy. They also 100% support a no mulesing process and animal ethicacy standard - meaning happy and safe sheep. The brand also supports recycling and has made 100% recycled ocean plastic flats and jackets, to give plastic a second life. Their Flats also contain a biodegradable sole, utilising organic materials where they can.

Stella McCartney shoes have been made from recycled polyester since 2012. As a result of being made from plastic waste, they use up to 50% less energy than virgin polyester.

The upper composition of all the Organic shoes is a unique blend of 60% organic cotton and 40% natural hemp, while the eyelets and shoelaces are entirely made of organic cotton, sourced in Vietnam, according to the internationally recognised organic farming standards. The insole of all the shoes is composed by a layer of natural cork, which is light, durable, impermeable and hypoallergenic. Superga®’s sole rubber is natural and manually extracted from the rubber tree forests of Vietnam, Malaysia and Thailand.
