I might be down for mid-brown but then those cordovan are just stunning.
Also, I have a pair of almost new chocolate suede chukka that I want to let go. They don't fit me as good as I would like. PM me for details.
I think the first picture is actually the vegano maron that Gentlement Footwear ran a GMTO couple of months ago. Calf, not cordonvan.... But thanks for posting the link to the cognac cordovan chukka. They are beautiful!!
