Every morning after walking the dog get my feet wet and pants were dirty. I got these boots just this week and had a couple of times on. Feet are dry and warm, and the pants also fit into the boots. At first I was a little skeptical that my calves + pants would still have space (have thicker calves), but those doubts were quickly gone. They are like already often described, very light and comfortable to wear (which you can not say of many rubber boots). Would she buy me at any time and it can only recommend. Even for women with thicker calves (widest point to 45cm). Have you ordered in size 40.
