Lots of re-play value. I fell asleep with them in one night and had no problems the next day. I took a chance and ordered my normal footwear size (despite seeing a few reviews that said product was smaller than expected. ?? I wore these around the house and to do some grocery shopping. I have just put it together this afternoon, so if I experience any problems I will come back and edit my review. Runs big as you can see from the picture. These are great shoes! I was torn between these and another company that had far more reviews. My kids love walking the dogs in the morning in toasty lines clogs instead of having to put on socks and shoes.
