Yesterday I received the shoes and dressed today to walking 6.5 km, I suffer from a mild overpronation. I have previously taken an Adidas sneaker, but who has now had its day for 6 years. And I felt primarily today on clouds, super damping. Of course, my feet have grown accustomed to the old worn out shoes and I had walking on the hook a little pain when I had finished, but it is simply because the Kayano 20 is a super support and my foot once again on a real must get used to running. So I can only recommend to continue to wear the shoe, because it offers the foot and also the overall performance feel a great comfort. At that size, I have to say that I actually wear a 40, I ordered him to 40.5 and it fits properly. And an eye-catcher is the shoe even further.
