A study examined if anatomical traits could predict super shoe benefits. Runners completed treadmill trials in carbon-plated and control shoes. Various anatomical and neuromuscular traits were measured.

The study found that hamstring stiffness and calf-muscle stiffness were significant predictors. However, these factors explained only a fraction of the variation in shoe response. Most runners still benefited from the shoes. Read more culture coverage.

The study concluded that anatomy alone cannot predict shoe performance. Runners should test shoes under repeatable conditions to find the best fit for their needs. Related: Study: Stroller Running May Reduce Overuse Injuries.
