Weighing in on workout shortcuts

More of a workout for your walk? Maybe, according to one exercise expert who tried a special shoe that promises to tone your lower level as you walk. In this feature on exercise cheats, gurus weigh in on products promising to do more while you do less.

THE PRODUCT: Skechers Shape-ups (starting at $110). Chunky fashionable sneakers designed to promote weight loss, firm calf and butt muscles, improve posture and strengthen the back. They have a soft kinetic wedge insert and a rolling bottom to simulate walking barefoot on the sand. Several styles and colors available for men and women.

THE EXPERT: "I must say that they are actually kind of cute," said Michele Olson, a professor of exercise science at Auburn University-Montgomery in Alabama.

Her first impression, though, was the heaviness of the shoe. She had to get used to the clunky feeling.

"I could feel it working in my calves and the arches of my feet," she said. "I had to keep my balance in check."

Olson said she was expending more energy, but isn't sure if that was because of the shoe's weight (similar to strapping on ankle weights) or the shape of the sole. As for posture, she didn't feel much difference, but as a former gymnast, she has no issues there.

THE VERDICT: "Maybe. I think if you are trying to shape up, it's more important what you do in the shoes than any shoe per se," she said. "If you like wearing these shoes walking, that's fine. If you are looking for weight loss from wearing them every day, I don't see that happening."
