My daily shoe at home is a pair of Allbirds Tree Runners, in a limited colorway, "Lux Honey with Cream Hush sole" which I would call 70's Harvest Gold with a cream sole. I live in Chicago, work downtown, do walk up to a mile and a half at a clip outdoors for my commute on lightly neglected suburban pavement. I wore them all winter, and they're not the waterproof ones, which was maybe dumb, but does get you to be a bit more mindful of where you step. A soaked wool shoe is not something you really want. My only other complaint about them is that they can be a bit slick on certain pavements when wet.
It was without a second thought that I brought them to the UK, and they performed pretty well. I should note I am a large middle aged man who works a desk job and it shows. In 10 days, including departure averaged 5.2 miles a day and 12.5 20 step flights of stairs (this was only somewhat skewed by climbing St. Paul's 522 steps). Weather was, uhm, somewhere between damp and wet, and temps were between 30F and 45 (one day we got the 45 for like an hour). My feet hurt after a two day stretch where we did 14.5 miles and 49 flights of stairs. Heels mostly, but again, middle aged, heavy middled, heavy stepper. Much like the MCU's Loki, my feet are burdened with glorious purpose... or at least a purpose and me.
I'm going to agree with their copy that they are great for travel. I think I might like something a bit more grippy going forward, and water resistance (nothing is really water proofed, in my experience). No discernible odor though I don't have especially stinky feet. I wear socks every day, so it's not like my feet are against the woolen interior. I only brought the one pair of shoes, and we didn't really go anywhere dressy (is anywhere really dressy anymore?).
I would caution against a colorway like the discontinued Honey Lux, as mine got some kind of dark stain fairly early in my ownership, and despite running through the washing machine, it never really came out.
The Wool Runner Mizzle looks like it might be the right place to upgrade for me, but maybe the Trail Runner Mizzle, my shizzle.
I want to recommend Rock 'em Socks. I've never had a sock as good as theirs... despite being a bit fussy about their care. Just the right grip and cushion, and it doesn't hurt that they have licenses for all the dork stuff I love.
