These are this season's trendy long boots (knee-high boots). Made of suede-like material (faux suede), they are soft to the touch and recommended for autumn/winter outfits. The length was longer than I expected, so I bought a different pair and these have never been worn. *Since there is no material tag, the exact material is unknown. It is a suede-like fabric.
