Nike showed off their new line of Nike+ footwear this week: the shoes that keep tabs on your movements.

Pressure sensors and an accelerometer on the shoes can keep track of distance, jumping height, and step frequency. The data is linked to iPhone, iPod, and web apps.

The shoes will be available on June 29 and will be available in basketball and training styles.

LeBron James will sport the new Hyperdunk+ this summer.
