Garmin Foot Pod SDM4
Monitor speed and cadence when running indoors. Now you can get all the information you need on your workout even if the weather doesn't let you head outside.
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.
