Beautiful shoes until you carry it!

I bought these ballet shoes in white in size 40.5. They came well packaged and on time with me. At first I was happy Trying to have as fit perfectly and was looking forward to the first training session with the new shoes.

BUT:

After the first half hour training me white lines are noticed on the parquet floor of the exercise room, which came from my shoes. This saw then made accordingly! You have in front at the top gray spots where the white layer is transferred to the leather on the floor and immediately became thin at this point.
For ballet slippers at the price (no, it was not the very cheap) I expect simply more. In addition, the seller is not to contact by e-mail, so that I could express myself in accordance with him. I am very disappointed and my trainer was whether the white stripes on the floor less than enthusiastic !!

In no way do best to the other colors I can not say anything !!
