ISPO Award Winner 2025: Kipnext by Kiprun introduces a new era of glue-free running footwear
For the first time, a globally patented process is being used that reduces the sole and upper assembly from 15 steps to just one. The result: the sole unit is manufactured using supercritical fluid foaming, completely without adhesives.
This radical streamlining reduces the carbon footprint by 26% and improves recyclability without compromising performance. The Kipnext delivers the usual cushioning, but according to internal tests, it is 50% more durable than comparable models.
