I have a pair of Niles that I wore thru last summer and about 3 weeks at WDW. I just bought a pair of the Athens flip flops while vacationing in Maui (I saw Crocs on tons of people over there) and was shocked at how much more confortable they were than my Niles. I remembered thinking how confortable my Niles were when I first bought them too. Made me start to think if others have found a point where they are just plain ol' sorta comfortable shoes and if I should spring for another pair of Niles.
