I really like these Klogs comfort shoes for my job. See I work as a nurse, and it is very beneficial to have comforable shoes that have backs. The klogs are perfect because they can be sterilized in 140 degree water / autoclave. The perma-white technology keeps the klogs extremely white and bright. They don’t tend to fade.  My favorite part is that they have removable insoles so I can use custom arch supports with them. This really increases my foot comfort level and I highly suggest getting a pair if you are a nurse or some other type of medical professional.
