Oakley's smart workout sunglasses offer real-time coaching and feedback

This is the Oakley Radar Pace. It's available now for $450, £400 or AU$640.

While it may look like a normal pair of athletic sunglasses, it's much smarter than that.

The thick frame houses a variety of sensors that can measure movement and elevation. This includes an accelerometer, gyroscope, barometer, and humidity and proximity sensors. There's also Bluetooth and ANT+ for pairing a heart rate strap, footpod, cycling power meter and speed or cadence sensors.

But these sunglasses don't have a digital display like some other smart glasses I've seen.

Instead, there are Micro-USB ports on each side of the frame for attaching earphones.

Not only does this allow you listen to music streamed from your phone during workouts, but it's also how you can receive coaching.

The Radar Pace can offer real-time coaching and feedback on your runs and bike rides.

The app will also create a training program that is tailored to you and your athletic ability.

The glasses use Intel's Real Speech technology, which allows you to ask and respond to questions in a natural way. You can ask a question, such as, "How's my pace?" and then follow it up with, "Is that good?" Think of it as Amazon's Alexa, but on steroids.

A touch pad on the left temple lets you change songs, adjust the volume, accept calls and activate Google Now or Siri.

The Radar Pace comes with a sturdy carrying case, detachable earphones and cleaning rag.

It also comes with clear lenses that can be used at night or on cloudy days.

The app provides ample post-run data, including a map of your route, elapsed time, distance, pace, calories burned, elevation and stride rate.

Here's a map of a recent run I did in New York.

You can even see all of the commentary from your workout. The Radar Pace was letting me know that my stride rate was too low and that I should be taking smaller, quicker steps to improve it.

Here's some more pictures of the Radar Pace.
