So far, it was the heels that were a worry for you. Now it has been confirmed that even trainers, that you wear to mimic celebrities, are no less harmful - they cause far more injuries than killer high heels.
And wearing the same trainers for leisure, the gym and other sporting activities also leads to problems.
Many people wear trainers known as the 'Lily Allen effect' after the pop star, who promotes them. Chiropodists say one in 10 patients wears the wrong type of trainer.
Four in 10 wear trainers every day, with more than half buying a new pair only every two years, reports the Daily Express.
According to research from JJB Sports, the trainer is the perfect shoe, when worn correctly. But misuse and overuse causes 60 percent more injuries than killer heels.
