The answer to this question largely depends on who will be wearing the shoe. People have different types of structures to their feet that can alter the size of their arches. So while one type of arch support might work for a nurse with high arches, it wouldn’t potentially work for someone who has flat feet. “The interplay between arch support and shoe also needs to be taken into account. A more flexible shoe for example may benefit from a more rigid insole, while a very rigid shoe may not need a rigid insole,” Dr. Koshimune says. “But this also depends on the foot structure, body habitus, walking surface, number of hours worked, steps taken during shift, etc.” Typically, someone with a flatter foot benefits from a stiffer insole with minimal arch support while a person with higher arches benefits from a cushioned insole. Speak to a podiatrist if you’re unsure about what arch support might be best for you based on your body and personal circumstances at work.
