Our expert says:
Your best bet is to actually seek a medical opinion as to what is causing the problem, otherwise you could end up paying out large amounts of money - you don't know that your one leg is shorter than the other.
Secondly - 3 year old shoes probably need replacing, even if you are light on them! Most shoes don't last longer than 1 year.
So this is my advice - go to a doctor, preferably a sports medicine doctor.
