I bought me the second time, so I can change. After many running shoes, these are my favorites. Nike free I feel the balls too and can use it only for short runs. Not this. I run mainly on asphalt, sometimes forests and meadows or gravel. For runners who do not need as much support and love to have loose shoes that offer still enough safety when running. :-) Under normal Staßenschuhen I have 39.5, with most running shoes 41, they fit me perfectly with 40.5.
