The product was delivered very quickly. From the optics, he liked super. The sounds which had the soles on hard floor surface, are a bit strange. This certainly has to do with the functionality of the product. In normal rubber soles it runs to quieter. In addition, I found that due to the sole condition is not so good rolling movements are possible. I would, however, keep the shoes (1 pair), but unfortunately they were due to the fact that I have to rely on deposits and generally by my hand, arise when buying shoes trouble, not suitable for me. That has nothing to do with the quality of these shoes!
