From 5Ks to full marathons, the GEL-KAYANO® 30 shoe is designed to provide advanced stability and softer cushioning properties. The new 4D GUIDANCE SYSTEM™ helps provide adaptive stability. This helps you experience a more supportive and balanced stride during your distance training.  Its midsole is revamped with FF BLAST™ PLUS ECO cushioning and a 4mm stack height increase. With approximately 20% bio-based content, this material helps create cloud-like softness in every step. The new PureGEL™ technology is strategically positioned below the heel for a smoother ride. It's 65% softer than conventional visible GEL™ technology, allowing your distance training to feel surprisingly smooth.
