It's super cool to be able to just throw on a pair of flip-flops now that the weather's warming, right? Wrong, says Esquire writer Christine Flammia, who considers the flimsy sandals to be the worst shoe ever created. "Do you honest-to-god enjoy the strappy tan lines they give your feet, or the way your soles turn black with dust and dirt and fecal matter when you walk?" she wonders about flip-flop devotees. "Do you like the unsupportive base, and how it forces your foot to flirt with plantar fasciitis? Do you like waking up in the middle of the night with foot cramps, your feet literally begging you to stop wearing the shoes that destroy both your muscle fibers and any chance at being stylish?"
