Can insoles be effective for flat feet? General insoles tend to prioritize softness and comfort, but this alone is not effective for flat feet. Prolife support insoles are [supervised by a physical therapist] and developed based on over 20 years of experience, combining arch support with an exquisite balance of firmness and softness, and BP shock absorption technology. [Arch Support with Exquisite Firmness and Softness] First, from the perspective of flat feet, the most important element is "arch support." Arch support is designed to emphasize the function of the arch, which is to absorb and distribute impact during walking. This is perfect for those with flat feet whose arches are lacking or insufficient. Prolife insoles can provide longer support by making the arch material firmer. These are the optimal insoles for flat feet. [Ultra-Strong Shock Absorption Pad] To alleviate the pain of flat feet, shock absorption to avoid strong impact on the feet is the second essential element. The BP shock absorption pad, developed by Prolife's foot experts after years of experimentation, minimizes the impact on the feet during work and reduces the burden on the feet. [Soft and Breathable Pad Surface] The surface is fluffy and elastic, gently and softly fitting the soles of the feet. It provides a comfortable fit for the feet and minimizes irritation. The three-dimensional mesh design allows for breathability even in the summer, preventing the feet from getting stuffy.
