What is Helion foam in On Running shoes?
Short Answer:
Helion is On Running's proprietary midsole foam designed to provide lightweight cushioning, durability, and balanced energy return. It works together with CloudTec pods to absorb impact while maintaining stability.
Introduction
While CloudTec pods are the most visible feature of On Running shoes, the cushioning system would not function without the material underneath them.
This material is called Helion superfoam.
Helion is the lightweight foam compound used in many On models to provide cushioning, durability, and temperature resistance.
Together with CloudTec pods and the Speedboard plate, Helion forms the core technology behind On Running shoes.

What Makes Helion Foam Different?
Helion foam was designed to address a common issue in running shoes: maintaining cushioning while reducing weight.
Many traditional foams either feel too soft or lose structure over time.
Helion foam aims to balance:
- lightweight construction
- durability
- consistent cushioning
- temperature resistance
This allows On shoes to remain comfortable in both hot and cold environments.
How Helion Works with CloudTec
Helion foam sits directly above the CloudTec pods inside the midsole.
When your foot lands:
- Helion absorbs initial impact
- CloudTec pods compress
- the pods then lock together for stability
This combination allows the shoe to provide both cushioning and structure.
