I've had these boot (in black suede) for a couple months now.  Got them on a lightning deal for $53, and it was definitely worth it.  They are very comfortable, and they look like expensive boots. I receive compliments every time I wear them.

I normally wear an 7.5, but I bought these in a size 8, since some reviewers stated they run small. However, I think I could have gotten away with buying a 7.5, since the size 8 are a little big. I would suggest buying these boots in the size you normally wear.

The boots are a little slouchy, but I haven't had the problem with one of the boots falling down lower than the other like some reviewers have; they seem to stay put on me. My only complaint is that the top of the boots run a little bit narrower than I am used to compared to my other knee high boots. It makes putting them on while wearing thicker skinny jeans a little bit more difficult. However, they are easy to put on if you are wearing jeggings or tights.

For those that like over the knee boots, you can actually flip up the cuff at the top and they convert to above the knee boots, depending on how long your legs are.

Overall, if you want a pair of knee high boots that are leather, and you don't want to spend the $200+ these are definitely worth it.  If I didn't already own a pair of brown boots, I would get these in the brown too.
