Mi-coach shoes support data recording function, but the shoes themselves do not have mi-coach chips. The small groove under the small sponge pad on the sole allows you to place the chip according to your own choice, and the chip needs to be purchased separately. Only high-end shoes will have them, belonging to smart chips, which can record heart rate, distance, heat consumption and so on when placed on the soles.
