I live in Arizona where sandals are worn all year long. In fact, when it rains in Arizona, we go OUTSIDE to enjoy it! These shoes are perfect for our weather. My feet stay cool during REALLY hot weather, do not sweat, and if I have to walk through a puddle, these shoes can take it. I ride my bicycle in them, walk, hike, etc. My other pair is a more enclosed style, and they work very well during our winter months, too! I would rather go barefoot all the time so finding really comfortable shoes are a must for me. Keen's are the most comfortable shoes I've ever worn...almost like I'm going barefoot. They do run a little wider than most shoes. But you must make sure you have the correct size. I purchased a different style of Keen's locally and found that I had to order a half size larger for them to fit properly. They are made very well, so they should last quite awhile. I have every intention of purchasing another pair (or 2) in the future!
