I'm a believer!
I had really hesitated at buying these. They were definitely more expensive than my regular flats and I had reservations about how they would look on my wide, flat feet. I was incredibly surprised that while the material is very soft and comfortable, it has enough body to shape the foot nicely. I had tried the Allbirds flats prior to this and returned them because they were not attractive looking on a wide foot. There was no breaking in period and I was on my feet all day. The shoes are very light and the insole that it comes with was also very cushioned. I didn't have any arch pain. I would recommending sizing half a size up if you have wide feet though. The fabric is not very breathable, so I still sweat, but I guess the ability to wash it should counter that.
