I bought a pair of these for my fiance, and he's had them 2 years or more. They have a classic look that those hideous rubber Crocs don't. In fact, he had me get him 3 more pair in beige(in case they change them) plus 2 in herringbone(not shown here). He says the bumps inside are like an oriental foot massage, every time he wears them. Also he looked at something about oriental accu-presure,and it appears that's what they do. Every area of the body(organs, etc) has a connection to the foot. Stimulating these pressure points, helps promote a healthy body, without pain, and less diseases!(not that these are the only ones with those bumps)

The first pair's still look great. Cleaning these are a breeze. I spot check with Dawn(dish detergent) then let soak in luke warm water. I then toss into washer on delicate cycle, and let air dry. I've read of others shrinking theirs, by washing& using the dryer, which is unnecessary.
