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.

"Never owned such a comfortable light pair of shoes"
— P S. (5/5)
"I love all my Allbirds & these are no exception. Comfortable from the first wear with a really supportive sole. I will take these travelling this year as they are light, comfortable & stylish enough for street wear & exercise."
— M H. (5/5)
"I recently bought 2 pairs: a tree runner and a tree Dasher. Both are very light and comfy. The colours are an easy match for traveling too"
— Desiree (5/5)
"Brought these to throw on when doing odd jobs and casual wear . So comfortable they’re now replaced my walking shoes !"
— Daisy M. (5/5)
"A great, all-rounder. Perfect fit, light weight, with great support, expecially, if like me you have ankle problems. These shoes hug without being restrictive and are breathable while still offering wet weather protection."
— VICKI S. (5/5)
"I purchased these to replace my old tree runners. I can see why they were 60% off, there is a groove at the back of the heel that rubbed terribly on the back of my ankle. No sports shoe should do that."
— Emma (3/5)
"So comfy from the first wear . Perfect for my Healthcare employment where I’m on my feet all day"
— Marion (5/5)
"Great to wear from day 1. I normally wear a women’s 11 so I can wear them m with socks but was pleased to see these come in half sizes . The 10. 5 is perfect."
— Mel (5/5)
"These are the most comfortable shoes I have ever worn. I usually have to wear shoes in gradually but not these."
— Kathy O. (5/5)
"Really happy with these shoes. My one ponderance is whether i should have bought the white/off white rather than black."
— F (5/5)
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
