Personally, I use them in the city as a delivery person with continuous 12-hour shifts. It is the third winter that I use them. They have now opened in 2-3 points where they have fabric. As a plus, I add that for 2 years I have never felt cold feet, they never got wet, they never smelled, and I have never worn a more comfortable boot. I would like to buy them again but I am not satisfied with the grip of the sole on slippery pavements where shoes of 25 euros would slip.
