However, you can’t be wearing any old flip-flops when you’re spending time on your feet, and a well-crafted sandal that holds your foot in place and supports the arch and sole is going to be key for maintaining comfort, even while you’re on a walk. In layman’s terms? Your shoe should not be able to bend at the sole, and it should be just as sturdy as any other pair in your closet. Proper sizing is also a major factor in making sure your shoes adequately pad your feet as you walk, yet 50% of the population is wearing the wrong size shoe, according to Galoyan. “There are four dimensions to take into account for foot size. You need to measure your arch length, your full length, your width and girth and go from there in determining your true size,” he explains. Believe it or not, the right size shoe may actually be slightly too long, provided it fits the other dimensions. Prioritizing sturdy grip and selecting a secure, well-made sandal will make your investment worthwhile when you’re wearing them summer after summer while feeling pain-free and looking as stylish as ever.
