I use these shoes for a while now for my martial arts training, and have to say it is (for me) the perfect shoes.The Sole allows a good grip on indoor floor, but does not hurt the training partner if you look at the feet occurs how the other of jogging shoes knows. The only thing to complain about is that I have heard from a coach with the same shoes, the shoe after a while to the Aussennäten on going because you at martial arts more lateral force brings to the shoes as while jogging. For me it has not yet occurred.
