I am a pretty hardcore water-walker / water-runner. Finding long-lasting, truly-supportive, durable water shoes for walking and/or running in water had been extremely difficult - until I finally found these! I LOVE these shoes. A) Great fit (I see a lot of size issues, size complaints, and size questions on this site regarding shoes, and I'm not saying anyone is right or wrong, but I will say that I ordered the exact same size in these water shoes as I wear in "regular" shoes, and the fit is perfect. I have used them several times now, and the fit remains great, with no uncomfortable rubbing/friction/blistering. They ARE close to being a tight, snug fit in terms of when putting them on, but honestly, they're fine. They aren't really hard to put on. With their nice tread on the bottoms, they provide great support in the water while water-walking / water-running, and I anticipate them lasting quite a lot longer than other water shoes I've previously just settled for. Thumbs up, big time!
