I have crocs, klogs, and birkenstock clogs that look like crocs. I had the Birkenstocks and the Klogs long before the Croc craze. I also had a pair of Quarks which are similar. I am a chef though(see my name!) and I wear them to my job now in the Dr's office because they're sooo comfy and they match my scrubs!
They also fit my wide butt feet.
Other than work I wouldn't wear them I am far to shoe snobbish to do such a thing.
And Snowy is right, I have pairs with holes and without. When I work in restaurants I wear the solid kind. In boring black usually but I do have a nifty yellow pair(in solid) that I wear if I'm feeling sassy!
The kind with holes I have pink, yellow, black, pink with skulls and this brownish color.
Really if they weren't so comfy and skid resistant... I would never wear the things but they are SOOO comfy and when I have to stand on my feet for many hours there's noting I need more.
