Did some searching for more information comparing Atoms vs Allbirds on reddit. I couldn’t find a ton, but here are a couple of relevant comments.
u/Schwma in this post about Ultraboosts vs Allbirds
I’ve been wearing them almost exclusively for the last 7 months, and they were my only pair of shoes for a 2.5 month trip throughout Asia.
I have the atoms, and they have help up very well. Usually my shoes compress unevenly due to over pronation, but I have had no issues with these.
They don’t breath well, due to being water repellant. This is both a blessing and a curse. I was still able to wear them in 20 Celsius plus weather, but once the humidity increased I found myself wearing my trail runners exclusively.
I am a fan of the minimal design, but I understand why others wouldn’t enjoy it. That is preference at the end of the day.
If you have any questions feel free to ask.

This quarter sizing looks and smells a whole lot like snake oil to me-:)…the difference between each consecutive half-size is 4.23mm and “quarter size” is “2.12mm”…keeping that small amount of offset in shoe production isn’t possible…https://footwearnews.com/2018/business/sneakers/twitter-roast-atoms-sneaker-startup-1202575607/
FIWIW, I love my Allbirds and would happily make the purchase again. Mine are about 7 months old and don’t seem to have any additional wear. I have the Tree Runners though, not the wool ones.
