I always bring water sgoes to wear on catamaran shore excursions and in the water when I am unfamiliar with what I may be walking on. They are very hot and do not provide support, so I don't wear them walking. I buy mine at Wal-mart. They tend to develop a funky moldy odor quickly so I throw mine away after the cruise. They cost less than $10.00. You can wash them or buy a "designer" pair.
