I bought the shoes in mid-June and I basically only take them off to sleep ;) I wear them in the woods, to work, and in the car, completely giving up sandals. I washed them in the washing machine. They are incredibly comfortable and very lightweight. I have a narrow foot and wear size 45/46. The size chart indicated that I should choose 45, and that was indeed the right choice. They fit the foot well. I wear them without socks and they do not cause any chafing. Despite the thin sole, the insoles provide pleasant cushioning. I have never had anything so light and comfortable on my feet before.
