I also have wide feet and I tried on the Teva Mush and my feet hung off the sides and the straps were tight. I loved the material, wish they fit better
I bought Reef flip flops from Dick's at the suggestion of some people on this board. While at first they were more comfortable than my cheap Old Navy flip flops, I eventually got blisters the size of quarters on my feet. I've never gotten blisters on my feet from Old Navy flip flops, but my feet do ache in them after wearing them for a while and they are dreadful in the rain. Going in September, I expect a lot of rain. SO I just order some Croc flip flops (Crocband ones) and I will see how those go before I leave. The reviews said they ran wide and were good in water. I am perpetually on the lookout for a good, wide, good-in-rain flip flop
