Achilles tendonitis is a condition where micro-tears in the Achilles’ tendon lead to inflammation and pain. It's generally considered to be caused by placing excessive strain on the tendon—often by doing “too much, too soon” when it comes to exercise.

Orthotics have been widely considered to be a safe and effective way for athletes to manage Achilles tendonitis by improving foot function and optimizing joint movement, load management, and shock absorption.

Below we list and discuss the best insoles for athletes who are suffering from Achilles tendonitis.
