It is the 3rd shoe of this kind that I have purchased and I'm quite happy with the product. The felt material wears very pleasant, especially the foot does not sweat, but the shoe is pleasantly warm. The only downside: much longer than a year is not the shoe without prejudice. Spilled heel parts and partly holes in upper to mechanical stress points are then the result. But this is probably not a quality problem, but the type of material and the real everyday wearing owed. Overall, certainly a worthwhile purchase, especially with a current price of good 30th
