I read the reviews and prepared myself for “too small, too tight” however, my feet are small and thin so I took a chance. They work for me and I love the style!! I love the bottom white tread, it cushions each step. And, for someone who is constantly walking on wooden floors at work, offers extra security that I won’t slip. The interior base has a coiled fiber of some kind; this can be irritating after awhile. The rough nature may smooth over, we’ll see.
