Crocs?
My wife bought them for me, my crew laughed and made fun, but I have to admit -they are comfortable. Good comfort without socks, fast drying, no marks. Climbing vertical walls surfaces?? They aren't THAT sticky, but I didn't find them slippery on deck at all. A few words of caution - make sure they fit well, too big and the slippery will be your feet IN the shoes - wear the heel strap; colors, I have the navy blue, very nautical, I'd suggest staying away from pink, orange, or yellow unless you really like abuse; ruggedness, mine held up all summer, until a game of tennis court dodgeball (don't ask) resulted in tearing out the strap, probably more stress than you'd likely put them through on board.T J
