Wearing shoes may change the structure of our ankle bones

New Scientist reports that wearing shoes is linked to slight structural changes in the spongy bone of our ankles. Because fossils have often been compared with the ankle bones of modern people who wear shoes, the finding could affect research into how walking evolved. Researcher Zewdi Tsegai says studying people who don’t routinely wear shoes offers a “window into the past” of how extinct human relatives moved.
