Co-founded by New Zealander Tim Brown, Allbirds unique casual & running shoes are made sustainably with natural materials.
Unisex casual shoes
While their women's collection only goes up to size 11 Australian, most Allbirds' styles are completely unisex. The running shoes, everyday sneakers, boat shoes, high top and slip on shoes in the men's sections are exactly the same as the women's shoes, they just come in larger sizes too.
The unisex men's range is available in the full range of colours up to size 15 Australian. Sometimes there is even a better colour selection in the men's section - call it a big feet bonus! 🥳
Choose from lightweight summer styles made with eucalyptus tree (machine washable too!) or cosy wool versions for cooler climates. They have even developed rain repellent mizzle shoes where a special "puddle guard" coating is applied to the merino wool.
Allbirds primarily use US sizing and convert to other shoe size formats. The sizing information on Allbirds website can be a bit confusing but they are happy to give personalised fit advice if you contact them. I found their customer service team excellent to deal with.
For men's styles, you should order a size 1.5 smaller than your usual women's size. For example, if you are women's size 13 AU, a men's size 11.5 AU is the same.
Unfortunately only Dasher running shoes come in large half sizes, but they generally advise to size up in wool styles & down in tree runners.
I can confirm that the tree runners run large & there is a big difference between the whole sizes too. I wear shoe size 9 UK (43 EU approx) and while the men's size 9 Australian tree runners (a women's 10.5) were definitely too small, the men's size 10 tree runners (a women's 11.5) were slightly too big. It's a real shame there are not half sizes available in more styles.
All styles are medium width but can stretch to accommodate some wider feet. The wool shoes are a little snug at first and then stretch naturally, while the tree material shoes are more stretchy but retain shape over time.
Limited Edition Colours
Note that many shades are limited edition and produced in one-off batches. The colour range and stock levels for limited edition shades also varies around the world.
Allbirds are quite expensive, so it's natural to save up over time or wait until you need new sneakers to try them. Just bear in mind that if you fall in love with a limited edition shade, it may not be around in your size for long. For new shades, you can sign up to be notified when your size is back in stock from the product page though.
Money Back Guarantee
If your shoes don't fit or you are unhappy for any reason, Allbirds offer free returns and a 30 day trial. So you can try them out & get a refund even after wearing the shoes out and about. A rare feature and a major plus!
Allbirds donate returned worn shoes to charity, so they don't go to waste.
