Quality lousy, first squeaky soles

So the quality seems to be pretty good. Have any defects in the processing may find. Also, the intake is very generous, just right for my giant Spann. The insole has a very pleasant footbed and it can be light as a feather run it.
However, I have PVC floor and on the floor squeaks unbearable. I just been annoyed. Perhaps there the time. Long review follows maybe in half a year.

Here the long-term review:
the Feathery has proven itself. The squealing with the soles are also, however, on stone floor not. That bothers still. After three (!) Months Insole began to "peel" to, ie the shiny exterior makes gradually a blunt synthetic space. In addition, the remains of the exterior then lying on the carpet. Not very nice.
All in all for the price not recommended! Value materials and workmanship at best a third of the price. One should not be blinded by the brand name itself. A star.
