Wow! So nice! I'm definitely making my way back to more black shoes after being brainwashed by the SF think. I'm putting some black shell cordovan longwings on the list.
When it comes to black longwings, I'm torn between shell or pebble grain calf. I don't have any pebble grain shoes as I generally don't love the look, but it seems pretty classic on that particular model and color. Right now I only have 2 pairs of black shoes and no black shell, just Grenson for Paul Stuart wholecuts and EG wingtips (Malvern on the 82). I really liked the Alden longwings in shell on the Grant last for the Black Fleece line.
