I switched to a brown CXL WT boot (41665) on the ML. I actually have enough WT boots but I kind of liked how I imagine a WT ML boot would look. I have quite a few Nat CXL boots but nothing in brown CXL yet, so that was another impetus. CXL is a big favorite of mine, wrinkles and all. Just love the patina it develops. Next time I'm in Paris or in Tokyo, I plan to see if my budget will allow me to splurge on a shell ML boot (if they have anything that is).
