I read this article recently and couldn't agree more with every point.
While on the topic of appropriate footwear, I found myself wearing sandals (way more strappy, less floppy, and no evil toe-post) to the beach this weekend. Once we arrived on the sand, I opted for nature's best pedicure and went barefoot. All I have to show for my one-day-a-year footloose foray is the most painful sunburned lobster-red feet of my life.
Let this be a lesson, kids: flip-flops are evil, and always wear sunscreen at the beach.
