I’ve only worn one pair of the colored ones once and the grey I have not worn . They are a size small , but I think a medium size human would fit these ok up to a size 8 . I always cut the tags out of my clothes so that’s why you see that in one of the photos . Buy all 3 for the price listed or shoot me a message if you want a specific pair . The colorful ones have the heel band . The grey does not . 💕💕
