The oldest known pair of shoes didn’t look like much, but foot fashion has come a long ways since prehistoric sandals. Joy Dolo and her co-host Daria lace up some matching footwear and take a hike through shoe history with reporter Nancy Yang. First stop is the Oregon cave where a 9,000-year-old pair of shoes was discovered. Then, a French king who tried to enforce a monopoly on his signature style, and the inventor who made shoes affordable for everyone. And finally, is the future of shoes… bacteria?
