MEN'S 361-KAIROS 4: Estate Blue/Azure Blue

Most stability shoes fight your foot. The Kairos 4 works with it. Built around a re-engineered platform geometry with a higher ENGAGE midsole stack and wider outsole base, it puts your foot deeper in the platform, letting the sidewalls wrap and support your natural stride. The result is cushioned guidance from first contact to toe-off, with moderate support that helps you run smoother, farther, and with less effort. One degree beyond what you thought a stability shoe could feel like.

Guided by Geometry

The Kairos 4 starts from the ground up. An increased ENGAGE midsole stack height and expanded outsole width work together to set your foot deeper in the platform, so the sidewalls can do what they're built to do: wrap, support, and stabilize. The wider-waisted base optimizes balance across your entire gait cycle, while the lightweight ENGAGE foam delivers 20% more energy return than previous generations. More cushion. More rebound. Less shoe between you and a better run.

Locked In. All Run Long.

Security starts at the midfoot. A reinforced Midfoot Lockdown Structure boosts foot fit and delivers a snug, secure feel from the first mile to the last. The Comfort Pressure-Free Tongue layers two breathable materials over an anatomically contoured design that follows your ankle's silhouette, using ultra-soft padding to reduce dorsiflexion pressure and keep the tongue exactly where you put it. No slipping. No shifting. Just run.

Built to Breathe. Built to Last.

The eco-breathable upper is crafted from soft jacquard mesh yarn using recycled materials, delivering wraparound breathability and secure, lightweight support. A dual-tone mesh treatment adds dimensional texture and a premium finish. The comfort collar features plush foam padding for smooth step-in comfort that holds up through extended wear. Reflective 3M at the heel adds low-light visibility when your run starts early or ends late.

Grip That Goes the Distance.

GekkoGrip forefoot rubber bites into the ground and helps propel you forward at toe-off. At the rear, High Abrasion Rubber Technology (H.A.R.T.) reinforces the highest-wear zone for durability that keeps up with your training load. An extended high-frequency moulded heel lockdown in the Stable Heel Construction enhances rearfoot support and keeps your heel planted where it belongs.
