I warn of the dangers of these types of shoes in The Barefoot Book.
How do toning shoes alter the human gait? They convert the natural stepping motion into a rolling motion. Unfortunately, this is not really unique to toning shoes; virtually all shoes make this conversion, but toning shoes take the ‘rolling step’ to the extreme.
I hope this lawsuit will educate more people to the hazards of toning shoes. Perhaps this will move us one step closer to having warning labels put on shoes that dramatically alter gait.
Now, if only one of those 20,000 women per year put the hospital by high heels would sue their shoe-maker!
