Since our soles are flat, with no built-in arch support, they’re probably the best shoe to use if you decide to add an insole.
So you know, though, our shoes are intentionally designed to let your feet bend, flex, and move naturally. Research shows that “supporting” your arch or immobilizing your foot with an orthotic can make your foot weaker in as little as a few weeks, while even just walking in a minimalist shoe can improve foot muscle strength.
