Bought these to wear to teach the motorcycle course when it's not raining.  I was a little disappointed with the height of the sides, they barely cover my ankle bones, which is a requirement.  But the more I wear them the more I like them.  They are comfortable for all-day hot weather wearing.  They are definitely NOT waterproof, but I knew that when I bought them.  They keep my foot comfortable all day in the heat.  They cup my heel, which is new to me, but after a very short adjustment period, I find that the cupping is something that makes them comfortable to wear all day.
