For years, Chris Nikic finished Ironman triathlons on feet that were screaming at him. There was no running shoe designed for the anatomy of someone with Down

On March 21 — World Down Syndrome Day — adidas launched the Supernova Rise 3 Adaptive, the brand’s first performance running shoe built specifically for athletes with disabilities. It’s the result of a multi-year collaboration with Nikic and GAMUT Management, a firm specializing in inclusive product design, and it’s the first shoe of its kind from a major running brand to receive the GAMUT Seal of Approval for meeting rigorous accessibility standards.
