Since the winter so far was not as cold, I could test the shoes the day before yesterday at slightly lower temperatures. Driven morning against 04.00Uhr at minus 8 degrees to the service, the ride is about 25km long and takes about an hour through the city. Conclusion: The feet stay warm. It comes with no wind. I had finally, after many years of searching and experiments with other models and various overshoes, no cold feet.
With the shoe you can walk quite well, cleats or spikes can be at my model do not screw that also not missing me.
I can recommend the full shoe.
