You may not know them by name, but you’ve probably spotted the wares of shoe company Johnston & Murphy at some point in your life. That’s because the company, founded in 1850, has been outfitting American presidents with their footwear since the days of 13th U.S. President Millard Fillmore.

Every POTUS since then has worn a pair of the company’s shoes, tailored to the fashion senses of each leader. In 1861, Johnston & Murphy made a pair of ankle boots for Abraham Lincoln, a style that they’ve since recreated for Barack Obama. (Lincoln’s feet, size 14, still rank as the largest of any leader they’ve cobbled for.) They’ve made custom white buckskin shoes for Woodrow Wilson and riding boots for Ulysses S. Grant. Bill Clinton got a pair of blue suede kicks, and Gerald Ford got loafers.

Hillary Clinton's candidacy may throw Johnston & Murphy into new territory. The company only started making women's shoes in 2008.
