Oh, we love shoes. The high heeled variety are our favorite. In a recent survey of 4,000 women, more than half stated that wearing high heels gives them confidence and 35% said their heels make them feel smart. But there’s a cost to pay for this found confidence, and it isn’t just our wallets that are feeling the pain.

Britain’s College of Podiatry reports that it takes just 1 hour, 6 minutes and 48 seconds before the average woman’s feet begin to feel the agony of being strapped into high heels. And some can’t even make it that long — with 20% of women saying the pain kicks in after just 10 minutes.

By wearing heels, we are altering the position of our bodies, causing serious effects on nerves, muscles and bones. Although it’s nothing we haven’t heard before, it’s still pretty scary and seriously painful stuff. Here’s exactly what wearing high heels can do to our feet and our bodies.
