These shoes are very comfy, squishy and nice to walk on. Seem to have a non-removable insole. I think I prefer the all croslite design with the nubs, because then if the shoes get wet or dirty I can just wash them off. Not sure how that will work with these insoles. The sizing for Crocs however is hard to figure out. I size 10 in sassari and 11 in Malindi, Cleo and Frances MJ. I got an 11 in these but they r too big. I am wearing them everyday despite the size because they r very comfortable and not as clown-looking as the regular crocs.
