I bought the shoes about 5 years ago already and they had very, very often. Now it was time for new. Unfortunately slipped my mind that they would be somewhat smaller. I had to order one size larger. It's an investment, but when I think about how long and how well that you walk in, they are worth the money in any case. I can stand and walk in it for hours. They are very convenient. Man does not sweat on the feet, still holding the shoes warm. For me, in the summer not quite as optimal, but they can be in spring or fall even in cooler temperatures attract very good without socks. Optimally, I find that you can replace the insole.
