My husband bought a pair of these crocs for our vacation...then later started wearing them after he got off work. He left the crocs in the car from day to day to change into directly after work. He started to complain about how he could no longer fit his crocs. I looked at them and said well I think they actually shrunk. I read other reviews and many others had complaints of people leaving their crocs in direct sunlight or heat and their shrinking. They are overall comfortable but beware of leaving them in the sun for they will shrink.
