Smart insoles are advanced footwear inserts equipped with sensors that monitor various aspects of foot health and activity. They can track metrics such as step count, distance traveled, and even pressure distribution across the foot. This data helps users understand their walking or running patterns and can be beneficial for athletes or individuals recovering from injuries. These insoles often connect to smartphones or other devices via Bluetooth, allowing users to access real-time feedback and insights through dedicated apps. Some models also offer features like posture correction and gait analysis, making them useful for improving overall foot health and performance in activities like running or walking.
