This is a genuine leather combat boot from UGG. Size is 42, which is 27cm. It has belts, so you can tighten them, and it should fit people with smaller feet. The opening is large, so it would look cool to tuck your pants in. The sole has a lot of grip, so it has the functionality to prevent slipping in bad weather. I think this is a great pair of boots that would go well with the currently popular darkwear style.
