On Cloudswift Men's Neutral Running Shoes Rock/Turmeric

Helion
Lightweight yet durable cushioned midsole foam that promotes high energy return and excellent temperature resistance.

Speedboard
It is the insole of the On shoes, a layer of liquid injection thermoplastic polymer that flexes, accumulating the energy generated by the impact with the ground to resist it during the thrust phase. The Speedboard works in conjunction with CloudTec cushioning technology to convert soft landings into explosive deadlifts.

CloudTec
The Cloud elements, placed in the sole, compress horizontally and vertically when the foot touches the asphalt and expand rapidly when the foot comes off the ground. All of this will give you a softer landing, a propulsive thrust and will prevent overexertion of the muscles to run longer.
