How is shoe energy return measured?

Shoe energy return is measured by conducting tests on the midsole foam of shoes. The most common method is through the use of a device called an energy return tester, which measures the amount of energy that is absorbed and returned by the foam material. The tester applies a specific amount of force to the foam and measures the energy that is released as the foam rebounds back to its original shape. This process is repeated multiple times to ensure accuracy in the measurement. The resulting energy return rating is usually expressed as a percentage, which indicates the amount of energy that is returned to the wearer with each step. This measurement is important in determining the performance of athletic shoes, as it can affect the wearer's speed, endurance and overall comfort.
