I have to start by saying that I thought the original Crocs were the fugliest shoes I'd ever seen.  I kept hearing how comfortable they were, but I couldn't get over how much I hated looking at them to actually buy a pair.  At one of my jobs, I spend hours on my feet and they would always ache when I was finished with my shift.  The look of these sandals is very modern and not at all what I picture when I think of Crocs.  I ordered a pair, wore them to work and wow!  My feet didn't hurt during or after work.  Incredibly comfortable.  So much so that I started wearing them to run errands, work in the garden, etc.  I've ordered another 2 pairs to keep for when I've worn these out.  I thought the "nubs" on the sole would be uncomfortable, but it's just the opposite. The sole is like a cushion on my feet and the shoe bends just enough when walking.  They're also very easy to clean.

I have only one negative... the small bump where the sole connects to the back strap is very rigid and sticks up above the sole.  It rubbed on my instep the first few times I wore them and made a sore spot on both feet.  I continued wearing them just because the rest of the shoe was so comfortable and now the problem has went away.  I think the shoe just needed to "loosen up" a bit.  I have average width feet, but I think if you had wide feet this could be a real problem.

I would recommend these to anyone that has to spend long periods of time on their feet or to anyone just looking for a comfortable casual sandal.
