I almost bought a pair of those this year, I knew they would be comfy. (I somehow lost a pair of black flip flops at a cold baseball game after I'd changed them out to warmer shoes and I was trying to replace them; wound up buying something else that I am happy with, though.)
Last winter I was looking for some casual (not work) clogs and wanted a certain type. To my surprise, I found that Crocs sold the ones I was looking for so I wound up buying two pairs. They are well made, super comfortable, and the price was right. Crocs have come a long way! But I still have two pairs of the original that I wear on occasion (the first being a pair I had to buy at Disney when I forgot the bag that contained all my shoes, and the second being the ones that look like sneakers, lol - I saw someone wearing them once and liked them, so when I saw them on clearance I scooped them up).
