Super comfortable boots. Have only had them a week so no idea how durable they are. I had them on all day at an outdoor festival in 90+ degree weather and with some light hiking socks my feet were not any hotter than the rest of my body. My feet stayed dry in all that heat. Good wicking. Went on a short hike along the Appalachian trail on very loose and uneven footing and the Keens were really in their element. Very sure footing and good ankle support on all conditions I encountered.
