Okay, I really REALLY like these sandals. They are the second pair of Keen sandals I've owned, the first being a pair of Newport H2, I believe. They've been awesome, worn them to work and on vacation and hiking and around town, you name it. They are about five or six years old, at least, and are finally showing their age. I'm relegating them to yard duty, working in the garden, mowing, etc. It is time for a new pair that I can add to my daily "retirement uniform" of shorts, Hawaiian shirt and Tilley hat.The Keen Clearwater CNX sandal seems to be the perfect "next step" for my retirement attire. I say "seems" because I only got them this week, but Amazon being Amazon and the online world being what it is, an immediate review is expected.The only caveat emptor I have for you is, double and triple check the sizing before you order. My old Newport H2 sandals were size 12 and a bit large for me. I wear 12 in just about all of my other shoes, including a couple of pairs of Merrells. So naturally I ordered size 12 for the Clearwaters. Nope, too small. Small enough to be awkward and almost painful to wear. I moved up to size 13 (there is no ... sorry, there ARE no half sizes above 12). It's just as well as 13 is the magic number. These are very comfortable, have plenty of toe room but are snug enough to inspire confidence.Oddly, put side to side with my old Newports in size 12, the new size 13 Clearwaters are the same length, but more slender and a better fit for my foot. The Clearwaters are also considerably lighter, a huge plus. I also like the slightly smaller rubber toecap.To sum up, the Keen Clearwater CNX are a step up from my old shoes and in the limited amount of use I've got so far, look promising. They seem to have the same high quality construction as my old shoes and even some improvement in the neoprene lining and inner sole. I expect to have many years of service from them and several adventures in my new retired life.Just beware the sizes and make use of Amazon's free return policy.
