Energy return in running shoes explained (2025)

This detailed guide from RunRepeat demystifies energy return in running shoes, explaining that it refers to how midsole foam rebounds to reduce wasted effort and boost running economy, with performance tied to advanced materials like PEBA, A-TPU, and TPU, plus design elements such as carbon plates and insoles. It clarifies common misconceptions (including no direct link between energy return and shock absorption), outlines standardized lab testing protocols, and discusses how benefits vary by runner biomechanics, pace, terrain, and shoe category.
