I got these for my honeymoon in Hawaii.  I went horseback riding, snorkeling, kayaking, deep sea fishing, hiking, zip lining.  I basically used them for everything, and they held up amazingly well within all the elements.  I went through streams, coral, rock climbed through lava fields, and even on the slippy surface on the boat it still had great traction.  I later used these for hiking up a waterfall in Utah, and I didn't slip once even when I was on moss.  I highly suggest these to any that enjoys the outdoors.
