I bought these shoes thinking it would be a nice change from rain boots and/or duck shoes. The shoes were very snug and not very comfortable to me. I would definitely say go up a size if you decide to buy these shoes.  It wasn't easy putting them on and taking them off. I think these shoes would still be hard to put on and take off even going up to a higher size. You can see by the picture that there is a very narrow opening to get your feet in and out. I sent them back and ordered some rain shoes by Sperry Top-siders.
