This Apple idea I fear is not as good as the last.
I-Kicks: Sneakers with built in digital display, and sensors. Peel back the tongue and get your average speed, distance traveled, calories burned, and current weight. Or no digital display, but Blue-Tooth capable and sends the information to your phone hourly. More expensive shoes, but cheaper treadmills lol
Feel free to offer suggestions on how we can improve this product. lol
