Apparently, the ubiquitous summer footwear of the 35 and under crowd is hard on your feet, ankles and toes. It all stems from taking smaller steps and scrunching up our toes to keep the flip-flop on our feet. The authors of the study suggest wearing sandals instead.
Shroyer’s analysis of the mechanics of flip-flop wearing isn’t the first warning about their dangers. The American College of Foot and Ankle Surgeons has reported an increase in heel pain among flip-flop wearers, especially in the spring, when they make the switch from sturdier winter shoes. The problem is exacerbated when people who are overweight or sedentary wear flip-flops. One of the most common sources of heel pain is plantar fasciitis, an inflammation of the connective tissue that links the toes to the heel bone. Being overweight and wearing ill-fitting shoes make it much more likely that you will suffer from plantar fasciitis. Thin-soled flip-flops without arch support aggravate the effects of any existing sources of strain on the legs and feet (such as too much weight or weak muscle tone).
Does this mean that you should throw out your beloved flip-flops or walk barefoot? Not necessarily. Like all good things, flip-flops are probably fine in moderation. Wear them at the beach or even for short jaunts to the mall. But don’t make them your everyday footwear. You can get much the same look from sandals that have a little more arch support or another strap that keeps them on (and gives your scrunched up toes a rest). Shroyer also suggests replacing flip-flops more often. “Usually people break their shoes in so they become more comfortable,” he says. With flip-flops, he says, “that is probably the point where you need to get rid of them.”
