During the summer, DH and I wear our Crocs all the time. However, we learned the hard way during our WDW trip last July that we can't wear them nonstop when doing all of that walking. Both of us ended up with blisteres on the soles of our feet! We caught this quickly, wore some different shoes for a couple of days, and were ok to go back to our Crocs -- only this time wearing them for only half a day-or-so at a time. Worn like that, they were great!
