Good morning on this brilliant Wednesday.



People have strong feelings about feet.

We know, because we asked New York Today readers, and an etiquette expert: Are flip-flops or open-toed shoes O.K. at the office?

The etiquette connoisseur Lizzie Post, the great-great-granddaughter of the etiquette expert Emily Post, recently published a 700-page book addressing topics including manners, politeness and behavior in public.

“Often, what people complain about with any kind of flip-flop or slide — when there is nothing holding a heel in the shoe — is, ironically, about the flip-flop noise, the slapping sound that accompanies that type of shoe,” she said.

Karen Boldizar, 59, who works in the cosmetics sector in Manhattan, agreed. “No one wants to hear you coming a mile away with the flip-flip-flip sound of an unsecured foot in a slide or flip-flop,” she told us. Even with the heat, she called for a flip-flop ban at offices.
