I love these sandals. I ordered a few similar ones from different brands to try, and then to send back on Amazon. These were the ones I ended up keeping. I have some Chacos, but they are too heavy for my liking. I bought these and they have been great so far. I wanted to wait a few months to make sure they were holding up to my summer activities. I am not sure if they are rated for water, but I have worn them swimming in lakes and rivers. I love it because then I can go cliff jumping, and not worry about stepping on cacti or sharp rocks when making my climb. They are light enough to swim and not feel like they are pulling you down, but thick enough that I don't feel every rock I step on. The only thing I have noticed with the water is around the 3rd or 4th hour the velcro on the back starts to come undone a bit. Not too bad, and I have the strapped a bit snug, so it's a smaller length than probably what it needs to hold under constant pressure.

I will be ordering more of these when my current ones ware out, which might be awhile considering I have pretty much worn them everyday for the last 2 months and they look and feel like new still.
