Having for years supported for training's and various competitions Adidas shoes, I wanted to try a different brand. Since I already have a couple of trekking shoes by Salomon and Speedcross 3 of the same brand already optically class found since they have come on the market, I have ordered these nearly three weeks ago. I have worn since just 10km 40km in training and on the last Sunday in relay marathon in Berlin. Who knows the local events, also know the nature of the "path" ... sauharter concrete floor! I had otherwise always a little trouble with his knees and the Achilles tendon on the left side - but not with this shoe. Conclusion: Perfect fit, lightweight, super cushioning and moreover a cool look. Caution - until half numbers definitely order a larger. I actually ordered size 44, I have size 45 1/3.
