Energy return in running shoes explained (2025)

Energy return in running shoes—how efficiently the midsole rebounds after compression—has become a focus area as advanced foam materials have improved. While better energy return can improve running economy and performance, the relationship isn't straightforward; factors like shoe weight, stiffness, and geometry must align with a runner's biomechanics, and energy return doesn't necessarily correlate with shock absorption. The article, based on testing over 500 shoes, clarifies common misconceptions about how energy return actually impacts running performance and economy.
