Back when I used to do Scout Swimmers/VBSS, I wore Chuck Taylors as well. They were cheap and fairly comfortable. The only downside that I had to wearing them, was that there was a lot of coral around where we were so they would get cut up quite easily. They weren't the best for traction either. However the pros outweighed the cons so I wore them.
We are rocking the black high tops for water ops too. Easy to put fins over, water easily drains, good traction and they're tactical looking. Other than diving, surface swims and short duration missions we havent used them much. I dont think I would use them for any type of long overland infils though.
