Allbirds fit true to size for most customers. If you have wide feet or are between sizes, we suggest you size up for all styles except our Plant Pacer (size down for those).
Did you know that our shoes are actually unisex? You can easily cross over to find shoes in your size.
Here’s how it works:
If you wear a women’s size 12, try a men’s size 10 or 11.
If you wear a men’s size 7, try a women’s size 8 or 9.

Lightweight, bouncy, and wildly comfortable, Allbirds shoes make any outing feel effortless. Slip in, lace up, or slide them on and enjoy the comfy support.
From materials to transport, we’re working to reduce our carbon footprint to near zero. Holding ourselves accountable and striving for climate goals isn’t a 30-year goal—it’s now.
We replace petroleum-based synthetics with natural alternatives wherever we can. Like using wool, tree fibre, and sugar cane. They’re soft, breathable, and better for the planet—win, win, win.
Exclusive offers, a heads up on new things, and sightings of Allbirds in the wild. Oh, we have cute sheep, too. #allbirds
