Developed at the ASICS Institute of Sport Science (ISS) in Japan, the 4D GUIDANCE SYSTEM™ integrates four key elements designed to enhance stability and comfort throughout your run:

Midsole Geometry and Design: Features such as a lateral decoupling groove provide dynamic stability, adapting to your stride and reducing impact.

Medial Convex Geometry: Offers enhanced support to maintain balance and alignment, ensuring a steady run.

Lateral Guidance Line: Newly designed to guide your foot through a natural motion path, promoting efficient and stable movement.

Midfoot FF BLAST™ PLUS ECO Foam: Delivers exceptional comfort and cushioning, especially for fatigued feet, ensuring you stay comfortable mile after mile.

The ASICS GEL-KAYANO™ 31 features an engineered mesh upper that improves breathability and a knit heel pull tab for easy on and off. The 4D GUIDANCE SYSTEM™ creates adaptive stability for a more balanced stride, while rearfoot PureGEL™ technology provides lightweight cushioning and softer landings. FF BLAST™ PLUS ECO cushioning, made with approximately 20% bio-based content, delivers cloud-like comfort. The OrthoLite™ X-55 sockliner enhances overall comfort, and reflective details improve visibility. The hybrid ASICSGRIP™ outsole ensures better traction. Additionally, the sockliner is produced using a solution dyeing process that reduces water usage by approximately 33% and carbon emissions by approximately 45% compared to conventional dyeing technology.
