This tiny foot pod is small enough to attach to your shoelaces or fit in the mid-sole pocket of compatible shoes. It's always ready to use and automatically turns on when you start moving. A small, replaceable watch battery powers the 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% accuracy for speed and distance. Additionally, this sensor measures running cadence to help you optimize your training.
Compatible with Forerunner 405CX, 405, 310XT, 305, 50 and FR60.
