From light jogs to full marathons, the GEL-KAYANO 31 is designed to provide both excellent comfort and stability. The "4D GUIDANCE SYSTEM" offers adaptive stability. This foam component, placed on the inside of the midsole, helps to restore the arch to its proper position with each ground impact during running, supporting a more efficient run. In addition, the midsole is equipped with FF BLAST PLUS ECO cushioning. This foam material is approximately 24% bio-based, providing soft cushioning while being environmentally friendly. PureGEL technology is placed in the heel and is about 65% softer than the conventional visible GEL technology. By changing the upper from the previous knit to mesh, breathability has been improved. The outsole's midfoot features ASICSGRIP for excellent grip, and the toe and heel areas feature AHARPLUS for excellent abrasion resistance, creating HYBRID ASICSGRIP for both superior grip and durability.
