When I was planning my trip for May I had intended to switch out my Teva Pretty Rugged Leather sandals with my Teva Mush flip flops, and Teva Olowahu flip flops. I then read the threads on here about the Crocs and bought a pair of the Croc beach models and a pair of the Croc Nile sandals. I wore them aound here (shopping and walking my dog) for about a month and still couldn't decide which was more comfortable, so took the Teva Pretty Rugged Leather, Teva Mush, and both pair of Crocs with me to WDW. The first day the Croc Niles caused two small blisters on my left foot. (I've never had blisters before.) For the next couple of days all I could wear were my two pairs as Tevas, as they didn't rub the blisters. After that I tried to alternate all four pairs. As far as comfort goes I'd have to rank them as follows: #1 Teva Pretty Rugged Leather, #2 Teva Mush flip flops, and a very distant #3 Croc Beach, #4 Croc Niles. I still love my Crocs at home and am not sure why I can wear them here, but not WDW. The Tevas were by far more comfortable.
I spoke with a lady at my resort who was wearing her Croc Beach and she told me that even though she was wearing them in order to trade them out, that her Tevas were also more comfortable then the Crocs. She said that her daughter had also gotten a couple of blisters, in the exact same place I did, with her Croc Niles (right where that horizontal ridge comes across below the toes). I'm going back in Sept and plan to give my Croc Beach one more try, but will have my Tevas to alternate with them. I won't be carrying the Croc Niles back though. I'll just wear them around here for short jaunts.
