I have long resisted the lure of the crocs.  However, last summer my mother bought me some imitation crocs at the beach for a couple of dollars.  They were amazingly comfortable; everyone told me that crocs were even more so.  In addition, my mother--the same mother--gave my wife a pair of crocs in 2006 that she still wears daily around the house.  This combination of comfort and long life made me cave and finally purchase a pair of crocs.  Because of philosophical (read vanity) objections to the design of the traditional croc, I opted for the most uncroclike shoe I could find that still held the croc comfort factor.  So, I went with the Crostrail.  I bought these and a pair of high end walking sneakers for a trip to a certain mouse-themed amusement park in central Florida at which much walking occurs.  These crocs were so comfortable that I wore them every day except one.  And, after that one day wearing the sneakers, I immediately switched back to the crocs.  After wearing the shoes designed for walking (with a price tag to match), my feet were in significantly more pain than the many days I wore these crocs.  I had broken in those sneakers walking an hour (roughly 3-4 miles) each day for a month.  Thanks to a handy pedometer, I can record that we were walking in excess of ten miles a day on our vacation.  For pure comfort and ease on the old feet, these crocs, which really aren't too bad looking, beat out a much more expensive shoe for day long walking of distances approaching a half marathon.  So, in summary, I would not hesitate to recommend these shoes.  As for durability and long life, we shall see.  However, I easily got my money's worth in their ability to make walking ten miles a day easy on my feet.  That is all.
