The Polar S1 foot pod™ should be just as much a part of your training as your running shoes. Accurately measuring your running speed/pace and distance, this essential piece of kit will be with you every step of the way. And even though it attaches to your shoe laces, it’s so light that you’ll forget it’s even there, which means it won’t affect your running performance.
• Robust, shock and water resistant to handle the most demanding of runs • Changing the battery is simple and effortless
