Story & provenance
React Debuts on the Hardwood
The Hyperdunk 2017 introduced React foam to basketball 鈥 Nike's then-new midsole material that would later anchor much of its running line. Cushioning split reviewers: WearTesters' Nightwing2303 criticized React as firm and uninspiring, while Stanley T. found it acceptable after break-in but preferred Zoom; Live for BBALL described it as 'a more firm and responsive Lunarlon.' The shoe came in regular engineered-mesh and premium Flyknit variants. Traction (a data-mapped pattern from Nike Sports Research Lab), fit, and lockdown were widely praised. Designer Ross Klien 鈥 who also did the UA Anatomix Spawn and Nike Kobe A.D. 鈥 built a clean, minimal silhouette. The 2017 is remembered as the last 'team-shoe' Hyperdunk before Nike rebranded the line as Hyperdunk X for the 10-year anniversary, and as the cushioning experiment that pushed Nike back to Zoom for 2018.
