Overview

The Asics Gel-Kayano 31 is a stability trainer designed to guide and support your foot through the gait cycle. It combines advanced guidance tech with eco-conscious midsole foam—FF Blast™ Plus Eco made with 20% bio-based materials—so you get softer landings and reduced environmental footprint in the same shoe.

Key Technologies

• 4D Guidance System™ — dynamically guides foot motion for on-demand stability.
• FF Blast™ Plus Eco — responsive midsole foam containing 20% bio-based materials for plush rebound and reduced weight.
• GEL® cushioning — targeted gel units for shock absorption in the rearfoot.
• Engineered mesh upper — breathable support that adapts to your foot shape.
• Durable outsole — high-abrasion rubber in key zones for consistent traction and longevity.

Design & Materials

The Asics Gel-Kayano 31 uses an engineered mesh upper with structural overlays that provide a secure, breathable fit. The shoe’s aesthetic balances modern performance lines with subtle style details so it works equally well on daily training runs and casual days off.

Materials were chosen to improve sustainability without compromising performance—FF Blast™ Plus Eco reduces reliance on petroleum-based materials and still delivers lively responsiveness.

Ride & Cushioning

On the road, the Asics Gel-Kayano 31 feels supportive and plush. The FF Blast™ Plus Eco midsole supplies a soft, energetic underfoot that pairs with GEL® units to absorb impact. The 4D Guidance System™ subtly steers midfoot motion, making transitions smoother and reducing fatigue over longer distances.

Expect a stable, confidence-inspiring platform for tempos, long steady runs, and daily mileage.

Fit & Sizing

The Gel-Kayano 31 fits true to size for most runners. If you prefer roomier toe box space or plan to use thicker socks, consider going up half a size. The engineered mesh upper conforms comfortably and the padded heel cup locks the foot in place.
