Walking on air: new study measures how insoles reshape foot skin

This study looks at how walking with different air-insole pressures (80, 160, and 240 mmHg) for 10 or 20 minutes changes the thickness and stiffness of the skin on the sole of the foot. Twenty healthy adults who are right-leg dominant and can walk without help will have their foot skin measured before and after walking using a special imaging technique called optical coherence tomography. The goal is to understand which pressure and duration combination affects the skin the most.
