First off I'll make a personal statement, Cricks are not allowed on my boat. Since I can't go fast, the boat must look good and I personally can't stand the look of crocks. Despite the many claims of comfort and reliability I simply can't stand the look and so have outlawed them from my boats. For those who love them and can get past the ugliness more power to you, I just have not been able to do it.
Now that being as it is, Sperry used to make a nice sandal, very simple, very cool to wear and made a great deck shoe. when on the boat. I went through about 4 pair before they quit making them and so, I spent this winter looking for a replacement. I'm now back to a pair of teva's. I need a shoe that works on the boat, and can get wet at the drop of a hat. These should work great.
Now all of the above is a personal opinion. Shoes are a personal item that everyone has to choose their own fit, form and function. My boat shoes are the same, grey or white bottom, as little topside material as possible. with the ability to get wet and still function while staying comfortable the whole time.
Good to see the discussion.
Have fun
