For the past 152 nights performing on the Eras Tour, Taylor Swift's outfits have each come with a pair of gleaming, twinkling, custom Christian Louboutin shoes—more than 250 pairs total, to be exact. Each night, she's sailed through her nearly four-hour set without missing a step. Swift's own talent and willpower are largely what makes those flawless routines possible, but the right shoes have helped her hit her marks even during fan-favorite (and slippery) rain shows. Now, Mr. Louboutin himself is finally explaining how.
In short: It comes down to those signature red bottoms' soles. Speaking with Instyle, Christian Louboutin explained that the painted leather soles on his usual designs are instead replaced with rubber for the Eras Tour. Every single pair Taylor Swift wears—from the combat boots with her new Reputation outfit to her fresh cabaret shoes for The Tortured Poets Department—has this secret, tiny adjustment that makes dancing, even in puddles, that much easier. "We typically incorporate this feature for musicians' tours to withstand the performances night after night," he told the outlet.
