The "barefoot running movement" seemed to go as quickly as it came on.
Vibram Five Finger shoes were all the rage with many companies doing anything they could to get a shoe out there that mimicked the five finger barefoot shoe and cash in on the movement. People bought these shoes and they were used from just walking around and daily work to going and trying to put all of your weekly mileage on. This is where people ran into trouble and injury. But first a little back ground.
Wearing basically any shoe on a daily basis is like wearing a miniature high heel (even the guys). There is so much elevation and cushion in the back of your shoe with the heel protection and cushion that it is raising your calcaneus significantly higher than it needs to be (we are talking mm or a cm here) and shortens the entire heel cord which results in changes in your entire posterior chain. Now this change starts early. As
Kelly Starrett has mentioned it, most kids run completely natural up until 1st grade when all the sudden it changes and they are in bigger, cushioned shoes and they begin to heel strike and walk around in these shoes. This is the start of a long process of being in cushioned shoes for most of your life.

So what's wrong with heel striking? If you picture running as almost low amplitude-high paced jumping you can start to see why heel striking could be so terrible for you. Your goal with running should be to spend as little time on the ground with each step as possible and use the dynamic ability of your body (i.e. your muscles) to propel you forward. When we heel strike we are slamming our heel/foot into the ground and increasing our ground time. When we do this we take all the brunt of that force through the static tissue of our body (i.e. our bones) and we end up with "shin splints" and progress on to joint damage or stress fractures. The amount of force your body must endure when running is at least 4x your body weight and if you aren't using your dynamic structures you're just asking for injury.
The good news is fixing can be easy. All it takes is practice and re-learning to run. Running is a skill just like anything else we learn to do so take the time to practice. First thing is get a pair of shoes that will allow your heel cord to be at its normal length all day. A shoe with no more than a 4mm drop (heel to toe) is ideal, the flatter the better. These shoes will also make running on your "forefoot" feel much easier when a big cushioned heel isn't in your way.
