Skechers USA, Inc. has launched a free Shape-Up N' Go application for the iPhone. The Shape-Up N' Go app is designed to track, map and share Shape-ups users' walking, running and hiking activities.

The app promises to Shape-ups into an interactive training experience by displaying and voicing workout times, distances, estimated calories burned, pace, speed and elevation; tracking and mapping routes; synchronizing with training logs; and sharing workouts with friends and family on Twitter and Facebook.

“With Shape-Up N' Go, it's easier than ever to learn more about your workouts, improve your level of fitness, and stay motivated and connected to the Shape-ups community,” said Michael Greenberg, president of SKECHERS. “Given the popularity of Shape-ups and interactive fitness tools, we expect that our new app will enhance users' workout experiences — as well as expose our product to new consumers.”

Shape-Up N' Go is designed to use MapMyWALK's intuitive data output and navigation features with iPhone's GPS technology. The app is also being developed for the Android and Blackberry.
