I had been looking for a pair of flat knee high boots for a long time and I finally found a quality boot that I can wear comfortably every day.  As others have said this boot looks a bit more like suede than shiny leather, but it still looks like a high quality material. These boots are very comfortable and I can wear them all day without a problem.  I am 5'6" but have a long torso and shorter legs, therefore these boots come right up under my knee.  I've been an athletic person my whole life and have 14" calves and my calves fit comfortably in the boots even with jeans on.  There is a buckle at the top of the boot that can be adjusted if you want the boots slightly tighter when wearing with tights or wider when wearing with jeans.  I have a wider foot and tend to wear 8.5-9 shoes.  I got 8.5 M and it fits perfectly.  The widest part of my foot is right under my toes (I have bunions) and these shoes give my foot enough room.  The boots fight a little tight over the top of my foot, but after wearing for a few days it feels like this part has adjusted to my food.  I went for the smaller shoe size that I often fit into and it fits perfectly.  There is room at the toe of the boot, and it doesn't feel like my toes are smashed in despite the slightly more pointed toe of the shoe.  They are similar to riding boots, but check out the pictures, the toe is not rounded it is has a slight point to it.  I had no problem with this, but if you are someone who doesn't like shoes that may make your foot look bigger this might not be the boot for you.  All in all, these boots are high quality, comfortable, and so far seem to be very durable.  I really like them.
