Before Travis Kelce could purchase stake in a racehorse named after Taylor Swift, he spent his very first NFL check on another classic item.

During an appearance on the WIP Midday Show Wednesday, Aug. 28, Kylie Kelce was asked a trivia question: Who spent their first NFL check on Marty McFly shoes, Travis, or her husband, retired NFL star Jason Kelce?

“Travis. It would never be my husband,” Kylie said with confidence.

She added, “I’ll tell you what, early on when we were dating, Travis came into town. I think with the Marty McFly shoes into Philly. I didn’t have a chance to meet Travis that time, but Jason told me after the fact how much of a hard time he gave Travis after Travis divulged how much he had spent on the shoes.”

The sneakers were inspired by the Nikes Michael J. Fox’s character Marty McFly notably wore in Back to the Future Part II. In the part of the 1989 movie set in 2015, the shoes famously laced themselves with the press of a button.

Kylie, 31, joked that although the shoes were “so cool,” Jason, 36, teasing Travis over the price he paid for them was “warranted.”

“He deserved a little flack for that one,” she said.

This isn’t the first time his big buy has been revealed. Travis, who joined the NFL after being drafted by the Chiefs in 2013, opened up about purchasing the luxury sneakers in an episode of his and Jason’s New Heights podcast last May.

“I had my eyes on a pair of size 13 Nike Air MAG ‘Marty McFlys’ — the coolest shoes that I’d ever seen in my life,” Travis, 34, recalled. “As soon as I got my check, I immediately went online and sourced them.”

He shared that he had “always wanted those shoes,” adding that they were also nostalgic for him.

“Watching Back to the Future so many frickin’ times and seeing what the Nikes looked like in the future and the fact that they were anti-gravity … those shoes were sweet! Self-tying … ugh man.”

He confessed “they weren’t cheap” and revealed they cost him $10,000.

Though his big brother teased him for the purchase in the past, it looks like it could pay off as they are now worth $35,000, per StockX.
