LOL - I had just stepped out for lunch after wrapping up the first leg of a plant inspection. Those weren't even my shoes, some loaner steel toes. It was those or strap on steel clapper over toes, I chose wisely.
Also note, I'm not wearing a suit (kaki dockers with a sweater pulled over a cream colored button down oxford shirt and covered in a London Fog raincoat. More importantly, in a professional international corporate environment three things will immediately get you laughed out of a board meeting - a brown suit, a green suit and a grey suit. Black or Navy Blue suits are the base expectation, both with black wingtips and belt. Oxblood leather would be a faux pas.
If I didn't need to be concerned with initial impressions I'd go wild on the shirt and tie. Always traveled with two white shirts and red ties just to be safe but all my other shirts were button down pastels (pink, purple, coral, cream yellow, pale green) and my ties were frequently Jerry Garcia and Rush Limbaugh creations.
In the Lambo pic I'm wearing my casual work shoes. Notice the nicely coordinated black shoes, black belt and black hardrock golf shirt (not to mention the black ride).
