I've always walked in flats and changed into sky high heels at the office (or just out of the rain) thinking I was saving my feet any long term damage. However, a new study shows that ballet flats, which seem to be comfortable, are making the foot work much harder than it should! "They give absolutely no support whatsoever in the arch," says Dr. Rock Positano, Director of Non-Surgical Foot & Ankle Service at the Hospital for Special Surgery in Manhattan. He goes on to say that 30% of knee, hip, and back injuries stem from foot strain cause by improper support. Wearing unsupportive shoes such as flats or flip flops can lead to inflammation of the Achilles tendon as well as tendon strains throughout the knees and legs. Ouch! What are we left with now, moon shoes?
