I find that these shoes are not at all heavy boots. They are quite thin and do not make big feet (at least at 42)
In terms of contents so there is a mixture of leather and other material that I can not describe but which has a grainy texture. The This material is at the ankle and goes around the shoe.
Warning, these shoes are not reinforced at the ankle and the front. To me these are shoes to town. I wore them in the sand sea amusement park and have suffered much. Even after cleaning they are not as beautiful as before.
In conclusion, it is comfortable shoes that keep warm in winter. Their design is nice and does too "clumsy"
