Helion™: Where soft meets strong

The Swiss-engineered superfoam that’s set to supercharge your run

Necessity is the mother of invention. So when we couldn’t find a foam that gave us what we needed for superior performance and a smoother running sensation, we created our own. Meet Helion™ superfoam.

Setting new standards

The secret? It’s the way the foam is constructed. Advanced production processes make it possible to combine rigid, stable sections with more flexible foam elements along the same molecular chains. In simple terms, we found a way to link different elements together for a fusion that offers benefits previously only possible with two separate materials, combining all ingredients for the ultimate run in a single superfoam.
