Purchased these for my husband and they fit true to standard US sizing. I like these because they don't have the holes in the front like most Crocs and are a little more masculine looking. My husband is a firefighter and wears these around the fire house instead of heavy boots when he isn't running calls. He loves them because they are easy to slip on and off in a hurry and are non skid, plus he can wear them in the showers at work. Great value for the price and are perfect for his needs.
