I broke my knee recently and needed flats to wear to church and with slacks while recuperating. These really fit the bill. The tee strap and heal design worked perfectly with my high arches and overly sensitive Achilles tendons. The arch support is good. I bought size 7W. The width is a little more generous than most of this size, so the shoes could be paired with a sock that is thicker than nylons, if desired. The length is perfect. I was able to walk in them easily with my knee brace. I liked them enough that I bought a second pair in another color.
