The making of Serena Williams' new Wimbledon 2015 shoe
Wednesday June 24th, 2015

You can credit Kobe Bryant and the Kung Fu philosophy for the design of Serena Williams' completely new on-court footwear for Wimbledon 2015. 

As Nike designer Aaron Cooper worked with Serena, creating the first on-court shoe engineered specifically for the dominating American, it was a small strain of Serena worry that helped shape the new NikeCourt Flare.

“At the time, I was having issues rolling my ankle,” the 20-time Grand Slam singles champion says. “So I wanted to create a shoe that would give me a lot of stability and make me a better player.”

But that stability wasn’t going to come in the form of an onslaught of hefty materials. Cooper and his team went a different direction, one that focused on a lightweight product. “At first, she was looking to achieve this stability through a bigger and more built-up shoe," he says. "But what she actually needed was the opposite. Stability can be achieved through a more minimal, low-profile shoe without sacrificing the protection you still need.”

That’s where Kobe’s signature basketball line makes an impact on the Serena-focused NikeCourt Flare. Cooper says convincing Williams that she should switch her thinking from bulk to streamline started with showing her the evolution of Kobe’s line and how his designs have turned more flexible and with a lower profile.

“Serena is friends with Kobe and she obviously respects his capabilities on the court,” Cooper says. “So she really responded to his story and was able to envision that translating to her performance. She embraced the idea and trusted the process.”

But Cooper wasn’t going to copy the Kobe basketball shoe for the tennis court. He needed a different source on which to base his design. And he chose Kung Fu.

“An insight we gained (from working with a Kung Fu master) was this idea of unencumbered flexibility,” Cooper says. “The thought is that a product should be an extension of your body.”

While not new at Nike, as the Kung Fu-inspired prototype resting inside the Oregon company’s design center has already spawned sneakers for training and basketball, Cooper grabbed hold of the concept of creating an ankle cuff. Using neoprene, Cooper built a sleeve for Williams’ ankle—giving her the feeling of stability to increase her confidence of movement—while keeping the rest of the shoe a flexible low profile.

“Mentally, when you have something around your ankle, you don’t think about it turning as much,” Williams says. “It feels like you have more balance.”

The cuff connects to an internal bootie and a midsole that doesn’t bond to the shoe, upping the cushioning quotient. With the material hugging the foot and ankle created, the NikeCourt Flare design went minimal on the shoe’s upper portion with composite materials designed for breathability and durability.

And instead of giving Williams a plank of rubber for the outsole, Cooper used pressure-mapping data to determine where exactly the shoe needed the most material for durability, allowing him to cut away material in other locations for a lighter, more flexible sole.

The NikeCourt Flare was designed with Kobe and Kung Fu in mind. Now it’s up to Serena Williams to channel all the inspiration into tennis.
