First of all I would like to say that according to Nike I am a size 10.5 and I ordered a size 11 expecting them to be a bit big but they actually fit perfectly. So they can work a little less. They glide like water shoes. When I first tightened the laces, I tore the plastic tab off the laces. Luckily the tab opens and I was able to replace it. I will be more careful in the future. They are very light and comfortable. I'm curious how they hold up over time.
