"There's not a lot of structure to this shoe so it's probably not for everyone. For me, they really did feel like the most comfortable pair of slippers but they stand up to a lot of walking. I bought these for a two-week trip to Japan (lots of city walking), and they held up very well. Because they are flats, I definitely felt some calf muscle soreness after a very long day of walking so I was happy to have a few pairs of shoes in rotation. I was looking for something that would be a little dressier but still comfortable and was very happy with this purchase."
