For the neutral runner, the On Cloudflow 4 is the ideal all-round running shoe. The Cloudflow is a real all-rounder. The shoe is great for your daily runs, but its fast nature also makes it ideal for your tempo and interval training. Experience the perfect balance between cushioning and responsiveness with this all-round running shoe!
Midsole
Helion™ foam in the Cloudflow 4 is lightweight and provides ample cushioning with every step, making it a comfortable shoe. Together with CloudTec® technology, a new level of comfort is achieved by combining soft cushioning with seamless weight transfer. This is because the unique Cloud elements collapse diagonally with each step. In addition, the midsole contains the characteristic Speedboard®, a plastic plate that bends while running and provides a responsive feeling when pushing off.
Upper
The Swiss-Engineered mesh upper provides flexibility and breathability in strategic places, while in other places the shoe is a bit tighter. The Swiss-designed upper of the shoe is tighter around the midfoot for a secure and supportive feel.
Outsole
This model has a high-performance rubber outsole for confident running at speed, even on slippery roads. The rubber components provide grip and increase your traction while running. Run at your own pace on the On Cloudflow 4 and push your limits!
