I'm not saying that everyone wearing these boots deserves your respect.
But, dollars to donuts, they probably do.  These are work boots.

Hardcore footwear, hardcore beer bottles.

Sure, an über rich obnoxious white dudes could just have grabbed a few pairs to go oystering in while on the Cape. But, they don't.  Both because they wouldn't know where to begin looking for oystering footwear and because you can do that particular activity barefoot.
