I was looking at the brown kudu chukkas with the lug sole and on a whim I decided to give Alden SF a call about these Ravello chukkas. They did happen to have my size so I ended up going for them. I googled the pics online and thought it was a nice color but am wondering why all the fascination with Ravello on here. I've read that it's getting harder to find for some reason so I'm guessing that is part of it. Does Ravello tend to lighten or darken with age?
