These are great shoes. I started buying these shoes for situations like trade shows when I was on my feet for a long time about 5 years ago, but they were so comfortable that I wore them for everyday and most business situations. They're extremely comfortable and look good, although not formal enough for a truly elegant business setting. What I like best is that you can put on a new pair (I have a new pair today, by the way) and after a few minutes your feet feel comfortable in them. Whatever the material of the top, you don't need to polish it, they clean well, but I've also polished them. My biggest issue right now is that I have about five pairs and they are holding up so well that at first glance (apart from sole wear) it's hard to tell which are old and which are new. If that's the biggest problem with shoes, it means you're lucky to have a shoe that really keeps you going.
