Polar S3 Foot Pod

Everyone knows how to run, but how many people know how to run properly? For that you need insight into the stride itself. That’s where the s3 stride sensor comes in. More than just speed and distance, this small and lightweight durable sensor measures each stride you take, helping you analyse the effectiveness and efficiency of your run.

• Provides you with information on how to improve your running technique – in competitive situations, shorter or faster strides can have a dramatic impact on your performance
• With interference-free speed/pace and distance data you’re able to evaluate and analyze your individual performance accurately
• The sensor can be mounted securely and unobtrusively to training shoe laces or placed inside the specially designed mid-sole cavity in adiFusion MC and adiStar Fusion running shoes
• The new S3 foot pod is an accurate way of measuring speed, distance, stride length and stride frequency
• It is 97-99% accurate, so similar to that of GPS
• The unit weighs just 21 grams and has an impressive battery life of 50 hours

Compatible with Polar RS800cx and RCX5.
