I was looking for a casual boot for the winter that was all man-made materials and these have worked OK for me, with a few slight complaints.

Cons
1. The upper material is pretty flimsy. The picture is a little misleading; I thought it would be more faux leather. It has more of a smooth/velvety feel to it. They feel a little cheap for the price ($65/$70)
2. There is no support or cushioning. I don't usually complain about that type of stuff, but it was pretty noticeable. I bought shoe inserts and they've worked pretty well.

Pros
1. I get lots of compliments on them! They look nice with jeans or tights.
2. Vegan materials

Despite my complaints, I can't really diss these boots because they've become my go-to boot for the weekends. So they've worked for me. One slight comment - these are not terribly warm and not waterproof. They don't claim to be, but just thought I'd throw that out there.
