Bought these for a trip to Costa Rica.  We planned on some excursions like river tubing and hiking.  I was able to wear these from one activity to the next.  They dry quickly, I would say a few hours in the sun or overnight in shady conditions.  My only gripe with them was sand, when sand gets in them its difficult to get it out.  Wearing them in the ocean caused them to fill with sand.  You had to remove the shoes and rinse it really well.  I would not suggest them as beach shoes.  I really like that they don't look like typical water shoes.  I have no issue wearing them with or without socks and they are comfortable all day.  I have wider feet and they fit well.
