I firmly believe Peluvas (and minimalist shoes in general) are good for people with flat feet (or high arches), despite what you might have heard. For starters, a study published in 2018 in the International Journal of Environmental Research and Public Health found that arch height doesn’t impact pain or function of the foot. Additionally, a randomized controlled trial of two types of in-shoe orthoses in children with flexible excess pronation of the feet (i.e., flat feet) found that adding orthotics made no statistically significant difference. However, there is research strongly suggesting that foot exercise can improve flat feet and wearing minimalist shoes, such as Peluvas, is an excellent way to exercise your foot muscles. Of course, I’d recommend adding traditional foot exercises besides walking barefoot or wearing barefoot shoes if you have flat feet.
