" Has it been a few years since you&amp;#039;ve stepped on one of those metal foot measurers at the shoe store? Well, we&amp;#039;re here to deliver some toe soul-crushing news: You might be wearing the wrong size \u2014 and it&amp;#039;s likely too small.

Yes, vanity sizing is even a thing with shoes, so shoppers who always pick the same size often don&amp;#039;t get the best fit, experts note. If you&amp;#039;re buying kicks online, order multiple sizes at once and be sure to try them on late in the day, when your feet are biggest. And if you do discover that you&amp;#039;ve been a size 9 all along, you&amp;#039;re not alone: Nearly half of women and one-third of men admitted to buying shoes that didn&amp;#039;t fit correctly, according to a study by the U.K. College of Podiatry.
