I needed a pair of brown flats to wear at work (retail, so if I'm working, I'm on my feet!), and these
shoes are fantastic! I also recently wore them around London, where they were also very comfortable. The only sign of irritation I've had is on the outside of my foot, underneath my ankle bone. There is a seam on the shoe in that place, as you can probably see from the pictures, and it rubbed the skin on my foot to the point of redness only. If I wore them day after day, then I can see the possibility of a blister in that area, but these
shoes have not given me any blisters whatsoever, and when I wear them it's for hours at a time, so I'm very happy with these! They are very cute, sturdy and well-made!
