YES, these are extremely comfortable.  I can wear them all day without my feet or back hurting.  I'm in my mid 40's and work on a concrete warehouse floor, so that is saying alot!  Also great for out by the pool.  They clean very easily - just spray off with water.

After reading all the reviews, I was a bit confused on what size to order.  I wear a 8.5 women's shoe.  I have a MAJOR pet peeve when people wear sandals and their toes or heels are hanging off the shoe-ARGH!!!  I bought a 9 in the Capri Women's Croc and they fit great!

I would have given these shoes a 5, but they make a funny noise.  Reminds me of one of those baby inter-active toys.  There's one part of the toy that makes a crinkling noise - that's the way these shoes sound.  The straps are made out of a plastic like material, which I'm sure is great to keep the strap nice and white and clean, but they make this annoying crackling noise every time you walk or move- very weird.  The inside of the strap is a faux suede, which is very comfortable.  Hopefully over time this sound will dimenish.
