Arlington residents have long been teased for their summer footwear fashion sense, but an anonymous, self-appointed member of the fashion police is hoping to change that.

A sign posted on N. Highland Street in front of Delhi Club implores passersby “This year let’s not do flip flops,” and it is signed, ungrammatically: “Thank you, an arlington county services message.”

So far, there is no indication of who posted the sign.

Fashion, however, might not be the only beneficiary of an anti-flip-flop trend; there could be health benefits as well. The flip-flops that can be seen adorning the feet and exposing the toes of many Arlington men and women as soon as the weather gets warm could actually be safety risks.

National Flip-Flop Day is June 19 this year. A smoothie cafe in Virginia Square annually gives everyone wearing flip-flops a free smoothie to celebrate the holiday.
