The built-in magnetic inserts are included as part of the overall insole design. The product's primary mechanism for making walking feel easier is the combination of cushioning and the textured, raised acupressure-style points on the surface. With each step, your foot presses against these points, creating gentle mechanical stimulation that can help the sole feel more active and less fatigued over time.
The role of the magnets is separate from this mechanical action. Some people choose products with magnets for personal preference. It is not necessary to believe in or rely on magnetic therapy to experience the potential benefits from the cushioning and textured massage surface. The overall effect is designed to come from the physical interaction during movement. As with any accessory, individual experiences can vary.
