I tried on the Crock flip flops, last week and they are also too wide for me. I was intending to buy the Chaco flip flops, but ended up with a pair of new Chaco sandals instead. I think I'll get the Chaco flip flops soon, too.
I have seen lots of guys wearing Chacos and Tevas, but not wearing Crocs, so far anyway. That may change, since they are so popular.
