I am very happy with the product. Got it yesterday delivered (went very quickly). The fact that the shoe is made of felt all around, it keeps your feet warm. The rubberised sole has a good grip, even on parquet and will not slip. The optics I find modern and athletic, have decided to orange for the color. In the summer I would imagine that the shoe is too hot then, but I've also specifically looking for a slipper for the cold season.
