They are very soft, lightweight, and comfortable to walk in. They widen and narrow with a buckle, which makes them fit perfectly on the instep.
For many years, I couldn't find open shoes that fit my feet, unless they had a strap or a ring, because the others are too wide for my feet.
I first ordered the black ones and as soon as they arrived, I tried them on and walked in them, so I also ordered them in salmon, brown, and white. The color is very nice, neutral, and matches with many colors.
