Disappointed in just about everything about these except the price and the color.  Don't trust the product description; it says something about 'hook and loop' closures on these, but there are none.  These are totally 'slip on.'  They look cute, but are not very comfortable.  The sole provides some slip-resistence, but no arch support and very little cushion.  They feel flat.  The fleece lining shown in the picture is deceptive as they are not at all warm and I don't have especially cold feet.  They would be better with socks on, but then they'd feel too small.  If you're determined to get them, buy a size up.  As for the tongue....I don't know why they bothered.  It is only attached at the very end, and sticks almost straight up from the instep, which also makes them 'not so warm' (or attractive, although the cat seems fascinated with the fuzzy attachments).  Since there really isn't much lining, they aren't very absorbent so if your feet get sweaty at all, (the slippers don't 'breathe well') they'll feel even colder.  I'll keep them on hand for running out to move the sprinkler in the summertime.
