The shoes made a first good impression. Delivery promptly. The scent was a bit annoying. Have the shoes worn over a winter, but not always, only at very frosty temperatures. They were also due to the underfloor heating at lower degrees of frost sometimes too warm. But that was not the problem. At the beginning of the second winter (2014), a shoe broke no explainable reason: left and right side tore the felt on the sole, namely deartig massive that the shoe was unusable. Hoping for a complaint option (2 years had not yet passed!), I turned to the manufacturer, unfortunately without result. Sture response despite protest: no replacement possible. I find very petty and incomprehensible. But I did not want more time to invest. But my warning: seller - not as usual at Amazon - not a bit generous. Rate therefore the purchase and add, for shipping and first wearability only two stars.
