The shoe is well made, especially the bonds hold even after a year still perfect. The ventilation of the foot work, miracles can not be expected, however. What bothers me, however the quality of the sole. After two days I was a bit skeptical about whether my shoes would really fit. A return is excluded, however, since the sole had worn visible already after the first day. Fortunately, the shoes have been run well (problem was the area of the Achilles tendon). But after 6 months the profile at certain points is already completely gone, because the material is simply too soft. This limits the life unnecessarily, as otherwise, the shoe would keep you safe much longer. Furthermore, it is now dangerously slippery on wet surfaces. These circumstances lead to the devaluation of three stars.
