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 restore the arch to its proper position with each ground impact during running, supporting a more efficient stride. Additionally, the midsole is equipped with FF BLAST PLUS ECO cushioning. This foam material is approximately 24% bio-based, providing soft cushioning while being environmentally conscious. PureGEL technology is placed in the heel and is approximately 65% softer than the conventional visible GEL technology. By changing the upper from the previous knit to mesh, breathability has been improved. The outsole features HYBRID ASICSGRIP, which combines ASICSGRIP with excellent grip in the midfoot and AHARPLUS with excellent abrasion resistance in the toe and heel, providing both superior grip and durability. Brand new, unused. Display item, so the inner tag has an "x" mark. No original box.
