"The On Cloudrunner 2 is a reliable stability workhorse for runners seeking extra support during their daily training. The latest version takes things up a notch with a revamped midsole that incorporates a lighter and bouncier Helion foam. This innovative material not only provides a softer cushioning experience but also delivers higher energy return to ensure efficiency in every stride. Meanwhile, the stiff Speedboard promotes a quick heel-to-toe transfer that helps guide the runner through their pronated phase. "
