We offer a 30-day trial period. If you're not sold by day 30, you can return your shoes for free with no questions asked, even if you've worn them out in the wild. To start your return or exchange, head over to exchanges.allbirds.co.uk
You will need your order number to start the process - you can find it in your order confirmation email (it starts with "UK"). Please note that socks must be unopened for a return within 30 days and all other accessories are final sale.
