Ah, summer. Soft breeze in your hair, grass between your toes, nasty calluses on your feet from going barefoot…
Don’t fear those calluses, though. New research has revealed that foot calluses — thickened skin that forms naturally when one walks barefoot — have evolved to protect the feet and provide for comfortable walking in perhaps ways that shoes can’t match.
Unlike shoes, foot calluses offer protection without compromising sensitivity or gait, according to a study published today (June 26) online in the journal Nature. Shoes, in contrast, reduce sensitivity in the foot and alter the way that the impact forces transfer from the foot to joints higher up the leg.
