LOVE these! They totally remind me of the jellies that came out in the 1980s. Super comfy Crocs soles - fit true to size. The outer shoe is a lovely flexible rubber - so no blisters with these! Also - I purchased the green - the green is very light (seafoam) color and turns to a dark blue in the sun. Has to be in full sun for it to change completely - but it will change a little bit darker on a cloudy day. The bottom also turns (I sat outside and played with them awhile!) when exposed to sunlight. It changes color back quickly when not in the sun. My only worry is that it will get dirty easy - but hey - Crocs comfort without the ugly style is perfect for me!
