Brown isn't "just brown". I've learned this more from matching socks to the ensemble than shoes to pants. Cardinal rule - the sock should "flow" directly from the pant color or* should "pop" and bring an important color from the outfit.
Calling all fashion-savvy gentlemen: Take your look to a chic new level with these fancy Brocade oxford shoes with coloured lining, wingtip cap toe, tone on tone stitching, and leather detailing. An absolute must.
