Brooks Koepka's Off-White™ Air Max 90 cleats had golf pundits scratching their heads over the weekend.

Commentators remarked, "He's got that zip tie on his left foot again," while Golf Digest wrote "What was up with Brooks Koepka's shoes at the Tour Championship?" and Golf.com pondered "What's the odd-shaped item attached to Brooks Koepka's Nike shoes?"

Well according to Koepka, "It's fashion, bro."

This is how the 29-year-old professional golfer described his Off-White™ cleats to a reporter when asked about his choice of footwear at the Tour Championship. After seemingly calling the reporter a "golf nerd," Koepka went on to say "I don't know how to explain it. It's Off-White. It's fashion. I guarantee the whole golf world has no clue what Off-White is, but it's fresh. If you're a sneaker head, you'll get it -- or into fashion. Sneaker heads know, yeah."
