Great customer service response. )The quality is good. The soles were incredibly comfy and squishy though so I think they have the potential to be very comfortable. This book should not be collecting dust! I was ready to use them, even if theyre a bit lacking, just because of how cute and cheap they are, but I have no disappointments yet. Not nearly as comfortable as my others. Wer allerdings auf Orchestrale Spektren oder Deep-Bass-Sound steht, sollte sich vielleicht noch einmal umorientieren. The reviews were mixed and it seemed people were receiving different revisions of the product. Adorable This thing is great!
