Race tuned CloudTec Sphere cushioning

Helion HF hyper foam
A lightweight Helion HF PEBA based midsole delivers outstanding energy return with soft, resilient cushioning that helps reduce fatigue and maintain speed over marathon distances.

Carbon Speedboard propulsion
A full length carbon Speedboard works with the midsole geometry to create powerful forward propulsion, helping you transition quickly through each stride and maintain momentum at race pace.

Lightweight breathable upper
The open weave upper provides exceptional breathability while delivering secure, adaptable support that keeps your feet comfortable from the first kilometre to the finish line.

Responsive dual layer midsole
A removable top layer of cushioning creates a soft, responsive underfoot feel while working with the lower midsole to optimise comfort and performance throughout your race.
