The Nappa leather has a more flexible and soft drape to it, making these boots comfy and less stiff around the ankle. The pebbled texture also adds some visual interest. While these have some signs of wear in the toes, they have a lot of life left in them! I got them several years ago but never wore them with regularity, and it's time to let them go to someone who can get more use out of them. They are a women's 9, true to size. Reasonable offers considered. Thanks!!!
