I just returned May 22nd from ten days at WDW. I carried Teva Pretty Rugged Leather sandals, Teva Mush flip flops, Croc Beach, and Croc Nile sandals. The first day I wore my Croc Niles and got two small blisters (one just below the big toe on my left foot and one on the tip of the middle toe also on the left foot. For the next two days I had to wear my Teva Pretty Rugged Leather sandals and Teva Mush flip flops. Over the next eight days I tried to alternate the shoes. In order of comfort I have to rank them as follows: #1 Teva Pretty Rugged Leather, a close #2 Teva Mush Flip Flops, a distant #3 Croc Beach, and #4 Croc Nile. I couldn't believe how much more comfortable the Tevas were than the Crocs. To be fair though, I didn't use antiperspirant on my feet the first day like I normally do. The funny thing is that I had been alternating the Tevas with the Crocs at home to walk my dog a couple of miles every day and had no problem with either the Tevas or Crocs. I talked with a lady at my resort who was wearing the Croc Beach model and she told me her daughter had also gotten a blister under her big toe with the Nile model because of the horizontal ridge just under the toes. I only tried the Nile model again on the next to the last day, but thankfully carried the Teva Mush flip flops, because I had to change less than an hour later.
