When WNBA All-Star player Elena Delle Donne first heard about Matthew Walzer, the teen who challenged Nike to design sneakers for people with disabilities, she took a particular interest in his story.

Delle Donne, who is the shooting guard and small forward for the Chicago Sky, has been vocal about her younger sister, Lizzie, who was born blind, deaf, with autism and — like Walzer — lives with cerebral palsy, according to Delle Donne’s website.

Delle Donne understands how difficult it can be for someone with a disability, like her sister, to comfortably wear sneakers. So, to show solidarity with her sister and everyone else who will benefit from Nike’s new shoes for people with disabilities, Delle Donne proudly sported Nike’s FlyEase Zoom Soldier 8 shoes at the WNBA All-Star game on Saturday, July 25, ESPN reported.

Delle Donne also invited Walzer to the game, and the two were able to meet and share their stories beforehand. Delle Donne tweeted a photo of the two of them following the game:

Returned my shoes to their rightful owner. Such a pleasure getting to know you! Thanks for coming!! @matthewwalzer24 pic.twitter.com/P54RZ0iN2J — Elena Delle Donne (@De11eDonne) July 25, 2015

“This moment, meeting Matthew, looking at these shoes and knowing that I get to wear them tomorrow and someday see them on my sister is by far the best part of All-Star,” Delle Donne told ESPN in the video below. “This is life-changing for so many people, and to be a small part of it is so special.”
