Love the fit and feel, but wool is an issue for some with sensitive skin!
I have arthritis in my feet, so comfy shoes are hard to find. I loved the look of these (and they are Canadian!) so I bought some Tree Skippers and they felt great as soon as I put them on. HOWEVER, I found after a half an hour that the wool insoles had caused my feet to turn red and hot. I seem to have a strong sensitivity to wool. I'm sad because I like some of the black slip-on designs that are only available in all-wool. I had been planning to buy some, so I hope Allbirds addresses this problem for sensitive feet and provides an option for ALL of its nice designs (and in black!) to be available in the non-wool format, and also includes a non-wool insole option-- I would definitely buy more in that case.
I switched out the wool insoles, and now all is fine with my Allbirds. I had an exchange with customer service about it on Facebook and they were great and very responsive.
