I wear a size 6 Wide shoe. My ankles are not thin, but not very large, either. The ankle-high nylon stockings are snug but not tight under my leggings. They don't roll down from the top, so there's no bunching. Neither do they slink down into your shoes. They look almost invisible on me, yet they keep my feet warm. I really like the reinforced heel to toe fabric along the bottom. It doesn't show above the sides of my shoe at all.
