Edit again: I still love them. But I have noticed there is no way in the dark, like if you have to get up during the night or earlier than a partner, to tell which foot is which. They are exactly the same on the outside with no indicator on which is right foot or left. You can place them that way. I got tired of my cats moving things around so I sewed a little button on the outside of each one to indicate right foot, left foot. Ha ha.Edit: They have stretched out to be absolutely perfect. I wear them every day here at home. I am in an RV, elevated, so cold air goes right under and up through the floors. My feet are never cold. So far it's down to 8F and my feet are warm.I love love love love these! They are soft and cute and comfy and warm. BUT.... I didn't listen to the advice to order up. I am a 7.5 and got the size for that and they are way too tight. Go up one size and you'll be very happy. I like them enough to walk with squished feet, so that tells you how nice they are. I am a plus size lady with larger calves, so they are tight there and cannot fold over.(Edit: they are stretching out over a few days, except for the tops. Inside, I'm right up against the toes, but that does not bother me.)
