When I first saw a woman wearing knit shoes, they were so tight they looked like socks, you could see the outlines of her toes, and I told myself I'd never buy a pair b/c they looked ridiculous. Then I realized they were not supposed to look like that, bought this pair to test it out, and I love them.I am normally a 9 wide, but the 9M fit perfectly, they definitely run wider than a medium width, and I'm not sure if it's the give in the material, that they run wide, or both. The shoes have insoles but they also come with a second new pair of thick shoe inserts for those that need the length of the shoe but the width may be too much so you add the second insole to take up the room.There is no support, but I prefer the barefoot type shoe, and if you like support, add or change out support insoles. They're very very comfortable and non slip sole is not visible like some shoes and make them look like orthopedics.
