We currently don't have any expedited options, but we're working on it! Our standard free shipping is about 5-8 business days. We hope to have some more options in the future.
If you need your exchange pair sooner than later, we suggest requesting a refund and ordering the next pair separately. You can do this at exchanges.allbirds.co.uk. This is also a great option if the color you're interested in is Limited Edition. Once a Limited Edition color is sold out it is gone for good, so be sure to get it while you can!
