The Gel-Kayano 30 is designed to provide advanced stability and softer cushioning properties, from a 5 km run to a marathon. The new 4D Guidance System offers adaptive stability, helping you experience a supportive and balanced stride during your long-distance training. The midsole has been redesigned with FF Blast Plus Eco cushioning and a 4 mm increased stack height. With approximately 20% bio-based materials, this material delivers cloud-like softness with every step. The new PureGel technology is strategically positioned under the heel, providing a smoother running feel. It is 65% softer than traditional visible gel technology, making your long-distance training feel remarkably plush.
