The Impact of Cushioned Running Shoes on Injuries and Foot Strength

The introduction of cushioned running shoes was based on the perceived idea of reducing impact and motion-related injuries without scientific evidence. These shoes led to a shift from making runners adapt to the running to adapting the shoe to the runner's foot, ultimately hindering foot strength. Research studies indicate that cushioning in shoes can make runners land harder, while support in shoes can lead to weaker foot muscles. Removing arch support can strengthen foot muscles. The cushioning in shoes can increase the force generated during foot strikes, akin to wearing gloves while hitting someone harder as it adds mass and protection. This suggests that cushioned shoes may amplify force exerted on the foot and knee, contrary to the intended purpose of reducing impact and injuries.
