First a little about my feet. I am a 58 year old woman who has worn a size 10 forever but as I age I am finding that in some shoes I need a size 11. I also have had issues with what seems like all my shoes since is was a kid. Rubbing in the wrong places, and not comfortable or having to "break them in" before I could feel comfortable.
Now to sizing. I first tried the Allbird runners in a women's size 10, wore them for a bit and found them too short. Given 10 is the largest size in women (guys - you really need to increase your size offerings!) I contacted Allbirds and they suggested a men's 9 for me. Since I was exchanging I thought I would try the wool lounger instead thinking it may offer more room for my toes. Nope STILL too small. Back to Allbirds who suggested a men's 11. Jackpot!
These are hands down the most comfortable shoes I have ever worn. I had them on all day yesterday, walked 2 miles, and at 8:00 pm I looked down to see if they were still on my feet! Yep. That comfortable. The wool let's my feet breath and the shoe just forms to my foot. I would have given them 5 stars if not for the back and forth on the fit. I was going to order the men's 14 for my husband but I do not trust they will fit.
I will definitely be buying more for me though!
