I wear this flats everyday to the office because it’s so comfortable. The padded sole is the main highlight as it provides support for my feet. I also bought foot socks for a comfier fit. However, a bit of break-in is needed to loosen the elastic a bit because it was tight at first wear. I have a normal size feet so it fits perfectly. I just get my usual size of US 7 for flats. I did not have any blisters from wearing this the whole time.
