Dries Van Noten boots query

  1. I'm considering buying these:

    but I notice there are some "variations" in color...do you think this is the result of discoloration or is it intentional?

    I've been wanting some grey suede boots for awhile, and you don't see DVN (for that price) very often. I'm concerned with a 38 not translating to my usual size 8, as well. Has anyone had any experience with DVN shoes that could offer advice on how they run insize?
