Unlike with increasingly sophisticated damping and stabilization systems flowing in recent years on the market running shoe models, this shoe is a pleasantly spartan. You can almost feel the ground under my feet, so its use spectrum excludes the extremely rough, rocky trail area. However, on asphalt, tartan, solid wood and meadow trails, this shoe is a pleasant, because very low-weight companion. And after years in übertechnologisierten, far more serious offenders breathe my feet currently is a natural. Care must, however, be sure to enter at the size of choice, because the shoes be very narrow and are working quite flat in the toe area. I have a normal 43 and let me provide 45 as a long-haul runners, but I believe that a 46 would not have been too large because a (problem) is already gone toe blue. Ambitious runners with "problematic" feet like lowering, buckling, platform, etc. probably should seek advice when running shoe experts whether the Nike Free is suitable not incorporating orthopedic support elements for them.
