It would give them five star would be my favorite slippers. Are the most comfortable shoes I've had, are flexible and feel that the shoe grab your foot without squeezing. Just notice it protected and comfortable. They only have a "but" that is important to me. On soil that is a bit slippery, like wood in the gym, slide and do not catch anything. If you do any sport that requires not grip the shoe on rough ground this model does not work. Otherwise these shoes are perfect.
