Had to bend, stretch and cuss to get this thing to not wobble and work. The band isnt too wide either, which I read could be a problem with the adult sizes. I got these in a size smaller based off of Euro sizing. UPDATE; 11/18/2020. These are the most uncomfortable slides I’ve ever tried to wear. I guess this can depend on the size of ppl eats as well though. Searched to buy a pair of court sneakers locally so I could try them on but very few people carry them. Buying more! Volume can get very loud. Great slippers until they wore out.
