Rarely do we give our feet the attention we need to strengthen them. Instead we tend to focus on replacing our shoes or adding an insert. Here’s a great video from Runner’s World that reviews some great exercises to strengthen your feet and help resolve as well as prevent injuries. Don’t rely on your shoes!!!
Dr. Campitelli is a podiatrist in Akron, OH specializing in foot and ankle surgery with an interest and enthusiasm for running as well as helping runners with injuries. For the past several years he has been treating running injuries in patients by fixing their form and transitioning them to minimalist shoes. Having treated runners with all types of injuries through conservative measures with orthotics and shoe gear changes to reconstructive foot and ankle surgery, Dr. Campitelli has brought what works best and is most current to his practice as well as the Akron and Cleveland running communities.
