I wear my Keens to work, for playing golf, literally everywhere in the summer outside and year 'round in the house.  They are the most comfortable shoes I have ever worn.
Bought them initially to hike the walls of the Grand Canyon on a rafting trip and they served me so well that I have seldom had them off since except when I have to wear a more dressy shoe.
Going down the Colorado they were comfortable, they offer excellent traction, allowed me to climb rocks safely, and they dried out in no time at all.

We live in a lake area and I routinely walk through the creek, into the lake, anywhere in these shoes. They are virtually amphibious and they dry so quickly that they can be worn soon after getting them wet.
The synthetic webbing is strong, the soles are very beefy and strong, and it is easy to slip in and out of them.
Guess I would give them 10 stars if I could.

I had not problem with sizing as others have mentioned but perhaps that has changed.
I am looking to buy another pair before they move on to another design because I like them so much.
