Which feature of a shoe absorbs shock and provides comfort?

The insole of a shoe is designed specifically to absorb shock and provide comfort for the wearer. Typically made from soft materials such as foam or gel, the insole cushions the foot as it strikes the ground, which helps reduce the impact on the joints and enhances overall comfort. A well-designed insole conforms to the shape of the foot, offering support precisely where it is needed, ultimately leading to a more comfortable walking or running experience.

Other parts of the shoe, like the outsole, are primarily focused on providing traction and durability on the ground surface, while the heel lift can affect the shoe's height but does not primarily serve the purpose of shock absorption or comfort. Arch support is essential for maintaining foot health and providing stability, but it is a feature that often supplements the insole rather than being the primary feature responsible for cushioning and comfort.
