Garmin Foot Pod
Monitor your distance and cadence when indoors, such as on a treadmill or a track at the gym, or when out of GPS range with your wrist-worn device and this foot pod. Also provides distance and cadence data when used with the FR70 series.
Small enough to attach to your shoelaces or fit in the mid-sole pocket of compatible shoes, the foot pod is always ready to use. A small, replaceable watch battery powers the foot pod for a year of training.
Unlike simple pedometers, this foot pod uses advanced MEMS inertial-sensor technology to analyze your movements and is responsive to stride-length changes to achieve 98 percent accuracy for speed and distance.
