What the study found
Standard orthoses increased oxygen cost relative to flexible orthoses and shoes alone during the tested runs. Changes in arch movement were associated with changes in oxygen cost.
Participants and protocol
Twenty-three recreational runners with flat-arched feet tested three footwear conditions during short treadmill runs in randomized order.
What this cannot establish
An acute economy result does not determine whether prescribed orthoses are clinically appropriate. The study does not establish injury outcomes or justify abandoning a device without discussing its purpose.
