On gifts Iga Swiatek custom shoes in honor of fifth Grand Slam title

She's pumped up—and she's got new kicks! In honor of her fifth Grand Slam title, and fourth at Roland Garros, Iga Swiatek was gifted a pair of custom sneakers by her on-court apparel company, On.

Swiatek has been sponsored by the Swiss company, backed by Roger Federer, since last year, and partnered with the brand to create a custom, on-court shoe which she debuted in the fall. These off-court shoes, though, are personal in a different way: White with gold accents, they feature special details that tell some of the story of the 23-year-old's career.

Swiatek showed off the sneakers in her champion's press conference, and later gave fans a close-up view of the special additions in multiple posts on her Instagram story.

A crown is etched on the inside of one tongue, and on the other is a trophy emblazoned with the Roman numeral V, representing her Grand Slam total to date. Her celebratory exclaimation, "Jazda!", the Polish for "Let's go!" sits near the back of the right shoe.

But the white kicks aren't just in honor of Swiatek's play on the court. They also feature a shoutout to one of her off-court favorites, the TV show Friends, etched on the side. (Swiatek had previously expressed her affinity for the classic sitcom as something that helped her feel less "lonely" in her teenage years, and played tennis with Friendsstar Courtney Cox at a sponsor activation for On when she arrived in Paris ahead of the tournament.)

Following the show's formulaic for its episode titles, which all begin with, "The one...," The one where Iga wins her fifth Grand Slam is written in glittering gold lettering.

If her Parisian hat trick had its own episode title, though, Swiatek says it would be "the one that's surreal."

"It was an emotional win, because I felt, you know, a lot of stress yesterday and today in the morning," she added. "And I knew if I'm going to just focus on tennis I can kind of fight through it, and at the end it all went how I wanted. So I just felt really proud of myself."
