Building upon the success from Kayano 30, Asics have tweaked the Kayano 31 with a few new features. This update introduces a new ASICSGrip outsole, delivering improved traction over Kayano 30 and a refined upper with an added pull tab to enhance ease of wear. The Kayano 31 continues to feature FF BLAST PLUS ECO foam and PureGEL technology in the midsole, for a smooth, cushioned and stable ride. The innovative 4D Guidance System Asics introduced in Kayano 30 has been rolled over into the Kayano 31, featuring a wide midsole surface area, medial convex geometry, lateral decoupling groove and guidance line which ensures a stable and supportive stride. The Kayano 31 is crafted for runners seeking a max-cushion, stability-focused daily trainer, perfect for easy and long runs. If you've enjoyed Kayano 30, you'll feel at home in the 31.
