Query: These crocs are not a crock!

These crocs are comfy, soft and not at all sweaty. These are my preferred shoes for the summertime, and were bought to replace a pair I have worn to death. The foam material they make them out of is soft on the foot, waterproof and cleans up amazingly well with soap and water. I thoroughly recommend them for a good, (very!) casual summer shoe.
