I had finally promised me warm feet of sheer anticipation and thanks to good reviews. Unfortunately, it was just nothing. As early as temperatures around 3 ° C plus I got cold feet. I then also different socks tested it, but nothing helped. Therefore, I give it back now and I hope the exchange works. Otherwise, I found the shoes to be very practical, waterproof and comfortable to wear.
Probably I will now switch to the more expensive Arctic models to keep up to minus 15 ° C.
