the quality is not convincing. When the Jack Wolfskin's understanding of quality products is, then I fear for one or another product for the brand, which is still in my possession. I have shoes now a good year, and at first I was more than satisfied. They fit (me) are wonderful and warm. However, fast to warm, so one is sometimes sweating. The fabric in the shoe is now torn in many places, so that the inner workings of the sole comes to light. But before that was fortunately already the cushion between fabric and rubber sole so far as that it runs on so ner type grid pattern! Add to this that the fluffy substance that is on the shoe, detaches a reason for some. As a result, I find all small black lint in the house and got on top now almost bare / slippery shoes. Yes, dear critics ... slippers have not eternal life ... That is why I chose yes for the brand ... For the price in relation to the life it do the cheap Ikea slippers however. Too Bad ...
