Ordered the 18 in the afternoon, received on 20 in the morning mail. Thank you for your speed! Neat package and in good condition. A little disappointed by this article. Ordered at the same time as the heated socks, and I preferred the latter which are less expensive half. First, the elastic is a little tight on the instep. But mostly, the sole is quite fine fleece, like the rest of the shoe, and not slip. In fact, they are rather shaped slipper socks. I had taken to walking with me, as with real shoes, but it's impossible. That's why I prefer hot socks, sui they at least cover the ankle and are thicker because they are in fleece interior, and faux fur on the outside. However, they heat up quickly and well, and the heat released is very nice. In addition, it is delivered in a fleece pouch. This is a good article to warm the feet, but beware: this is not true slippers and elastic top is a little tight!
