If you’re still on the fence, try a simple experiment: run a mile in track shoes with socks, then another mile without. After the second run, take off the shoes and smell your feet. If your own face recoils, you have your answer. Congratulations—you now know why civilization invented socks.
Plus, without socks, you’ll have to wash your track shoes after every single use, which is like trying to dry a cat in a microwave. Just don’t.
