I wanted sandals that were similar to my old Keen H2 sandals I got years ago and went for them. They run a bit small, order 1/2 or 1 full size larger. They are very comfortable and appear to be well built. Only time will tell. They seem to tolerate mud and water well. To clean them, simply wash them off. The strap on the back of the heel is adjustable. nice gesture. All in all a decent sandal for hiking, beach, mud and just walking around and I can wear them most of the day with no problems…
