The latest trend of toning shoes such as MBT, Sketcher Shape Ups and Reebock Easytone are claiming that they help you burn more calories, tone your legs and bottocks and improve overall posture.
A recent independent study from the Amnerican Council on Exercise shows that none of the "fitness shoes" tested helped the subjects burn more calories or exercise muscle groups more intensely than a typical running shoe while walking at a 3.0-3.5 mph pace on the treadmill.
Truth in advertising or just a current trend? You be the judge.
