The ASICS Kayano 31 is a stability-focused running shoe built for runners who log serious miles and need dependable support. It excels for daily training, long distances, and anyone requiring motion control features.
This shoe packs custom gel mold technology and a wider upper (98.9mm) that wraps your foot securely. The 40mm heel and 32mm forefoot stack (men’s) deliver a plush, cushioned ride without sacrificing structure.
Grip stands out here—the shoe scores 0.83 in lab traction tests, meaning you stay planted even on wet surfaces. Real-world testers confirm the Kayano 31 handles rain and varied terrain with confidence, making it versatile for structured training.
Build quality is solid throughout, with a secure fit that transitions smoothly from easy runs to tempo work. The shoe weighs 10.8oz (men’s), so it’s heavier than lightweight alternatives but trades that for protective cushioning and stability.
