Quality defects I can not tell. Shortcoming, in my view, the shoe is in the forefoot very wide, which is disadvantageous in my rather narrow feet. The sole is not designed for wet asphalt or even snow.
The shoes I run in the competition (runs from 10 to 21km and within the framework of triathlons) because my pure and lighter competition shoes but prepare problems immere me. Have in the last 2 years about 15 pairs of shoes bought but next to the tubes 100, from the same manufacturer, this is the only shoe I now buy again me.
For - in part - far below EURO 100 I have a really good pair of shoes found. If the shoe forward slightly narrower, he would fully deserves 5 stars!
