Problems may occur when people have too-high of an arch or - in most cases - a low-lying arch. If a person has an unbalanced foot to begin with, arch problems can occur even more often, whether they are wearing flip-flops, ballet flats or other types of unsupported footwear. Foot fatigue is inevitable, and especially if you are overweight. According to the National Foot Health Assessment 2012, very overweight people were more likely to rate their foot health as fair or poor, were more likely to be experiencing a foot issue and a foot issue that caused a high level of pain.
"There's a natural tendency for an arch to settle over time as we become heavier, older and a little less capable of repair," Levine said. "Our Achilles tendon tends to give way to supporting an arch."
Wearing shoes that constantly rub against the foot may also lead to blistering and fungal infections, Levine said.
While some people can't avoid foot problems - even people who don't wear shoes get bunions, which shows some health concerns are hereditary, Levine points out - what type of footwear we decide to put on makes a difference. If you want to show off your toes, aim for sandals with arch support like Teva-brand shoes. And, for proper arch support and to keep your feet happy, don't be afraid to wear some sneakers, Levine reminds.
"If you wear a good pair of lightweight Nike shoes that has laces, you'll notice 'There's a little bounce and pep in my step,'" he assured.
