I have shoes now 2 weeks, you have however not worn every day. The first thing I noticed was that the sole is very thin. There is virtually zero padding available under the foot. Thus, the ride is not particularly pleasant, because you step on very hard. Especially at the heel, I find the unangenehmt. For days when you walk a lot, I have therefore not attracted. Already now, after this very short time, the adhesion of circulating white edge begins to peel: both the kink when rolls while running, so at the level of the ball of the foot, and at the foot inside over the entire length. For the price you could not expect much, but this is really appalling. Get the shoes are now trying to return. Something ought to keep at least half a year (summer season).
