I bought these shoes just before a trip to Niagara Falls and had them shipped overnight. Thank goodness I read the suggestions by other reviewers to order 1/2 size up bacause these shoes definately run small.  I ordered a 9, usually wear an 8 1/2, and I could possibly have ordered a 9 1/2 because my toe is at the end of the shoe(but not cramped enough for me to be unable to wear them).  That being said, these shoes really are comfortable with no break in time required.  I took them straight out of the box and wore them to walk all around Niagara Falls without any discomfort. And they are waterproof!! I tested it by wearing them on the Maid of the Mist boat ride to the bottom of the falls. I got soaked but my feet stayed dry!! I would definately recommend these shoes to anyone and I'm considering getting another pair for myself!
