i ordered the white/black pair of the athens thong sandal and was really excited to get them.  i have a generic pair that looks exactly like them and i wanted to feel the difference.

the difference is in the croc!  they are cushy and bouncy and just like a regular croc, feel good on your soles.  i could stay in them all day ... EXCEPT for the fact that they run extremely large!  i'm a size 8 1/2 shoe, sometimes a size 9 sandal because of the way the straps rub on my feet.  i have other crocs and always order a size 7 (and they normally fit very well).  i ordered the mens 5/womens 7 and they are so big on me.  it's mostly width, the straps are very high and wide and don't rest on my feet at all.  i end up clenching my toes a little bit around the front because there is a little "slip" there.  there is also some extra room in the back but nothing horrible.  again, it's primarily width.

but it's a unisex shoe, so, i'm assuming the extra width is to accommodate a man, should he choose to buy these.  my suggestion would be to go two sizes down (in my case, 2 1/2), so that the width is not a problem, unless you have rather long feet that would then cut length in the back.

i gave these shoes a five because they are nice looking, priced fairly, and comfortable. ... i imagine even more so if you're able to find the proper size.  with most sizes being men's/women's, i'm sure it's going to be a little bit harder to do than with a normal sandal.
