Would've taken a pic with the Lemaire boots I had too, but I sold them.
MMM / Loake / CDiem
SLP / SeF / MMM
I ordered a 41 in SeF, the MMM and SLP are 42's. I like a little wiggle room in my shoes. YMMV. I wear 42 in CP, 42.5 in MMM sneakers mostly. My 42 SLP sneakers are a little loose, same with my Raf vandals.
From what I can see, the jodphur and chelsea boots have a much better shape than the side zips.
