I love these clogs. I work long hours on my feet.  I used to wear Dansko and Sanita clogs but started having problems from the lack of cushioning on the balls of my feet. I decided to give Klogs a try after a recommendation on a chefs' web group.

They did not require breaking in at all.  It's like wearing slippers because of the thick insoles.  I like that the insoles are removable so you can change them out if needed.  I have not worn my other clogs since buying these.  My foot pain is gone and my back pain has improved.  I would highly recommend these clogs.

After 2 months, these shoes show more wear than my old clogs. The leather is not as durable (looks faded and lost their shine) and the insoles are less "coushy."  I still stand by my recommendation but with slight reservation.  Some of my coworkers really loved my shoes and have since also converted to the Klogs brand.
