I have a very high arch and medium width feet. I have tried almost all comfort shoes available and the only brand that feels me is Alegria. I also tried different styles of Alegria and Kleo is just the best.The best thing is that it has superb arch support, thick platform makes my foot bed relaxed and not hurt at all. I all feel very securing these shoes and I don't twist my ankles as in other shoes.There are three issues i want to address in Kleo sandals :1. The fit slightly small. I'm size 39 in European shoes (I'm from Europe ) and my toes almost at the edge of the shoe. I tried size 40 and they are too long. I wish they would make sandals in half sizes as they make in some of their close toe shoes2. Because of the textured insole (not smooth genuine leather) and wide velcro straps these sandals can be a little hot. It was overwhelming for me at first and I'm used to it now3. I wish the the insoles come in dark or black colors. Since they are made of the the suede like material dirt and dust gets trapped in it very easy. So after a few wears your insole will be looking not so fresh. I bought a special eraser for these kind of insoles but it doesn't work. I personally hate when shoes are dirty inside and it's a very big turn off for meOtherwise, these are very comfortable sandals and I highly recommend them
