@BostonHedonist - re-reading my post, it came across as quite preachy. That wasn't the intention - my apologies. I'm actually a big believer in everyone assessing their own risks, and choosing whatever gear you like. IE, we're all big boys and girls and can make up our own minds.
A cousin of mine had boots very similar to the Dainese Latitor ones shown above - they were stealthy enough for him to wear with business-casual clothes in his job as an IT Manager. He had race-style boots, but got sick of always having to carry a second pair of shoes everywhere. The soles on the ones he had were reasonably flexible too, which is important if you want to actually walk around in them. I can't remember exactly what his were, but they were that same style.
