This is my first pair of Crocs. They are very comfortable shoes to wear. I feel like I'm wearing slippers! My feet are often cold, but these keep them warm very easily. Very roomy and soft inside. I usually wear a 9.5 US men's shoe size so I ordered a size 10. I even have a wider width, but these Crocs seem to have plenty of room. However with socks on the shoe becomes tighter and way too warm.
