I love these and wear them to work frequently. I am an elementary school teacher. I am size 11 in shoes and flats, boots, and heels are usually a problem for me because my feet are a bit wide. These are super comfortable and stretch after you wear them. The downside is they turn my feet black. I wear them with black no show ped like socks which mainly solves the problem. They are so comfortable it's worth it to me to deal with the dye on my feet.
