I am a nurse, on my feet for 12 hour shifts. These are my favorite shoes to wear to work. They have been comfortable from day 1. I have a hard time finding shoes that are comfortable, and always wore Crocs before. I am also able to find these in size 10.5, rather than having to go to a size 11 like I do in most brands. I have a hard time finding comfortable shoes, and tried Privo Mesa, which isn't quite as comfortable. They might not be for everyone, but I'm sold on them.
