Thank you! I think that the reason that both suede and grain work well with cords is that they're textured. I've been struggling to work out what shoes went well with cords. The important thing, to my taste, is to also have some contrast in the shoes and the trousers so I would think that a snuff suede pair of boots would work better here than dark brown. So, texture for both trousers and shoes but contrast in the colours feels right to me.
