Much like how the network of muscles around the hips, pelvis and back act like scaffolding for the spine, the tiny muscles within the feet are responsible for supporting the arch, absorbing load and keeping you stable when you walk or run.
“You put four to six times your body weight through your feet when you walk,” said Courtney Conley, the founder of Gait Happens, a Colorado-based online education resource focused on foot health. “And 11 times your body weight when you run.”
These muscles within the foot, known as the foot core, are activated when we walk barefoot but become dormant and weak when we wear narrow, cushioned footwear, Dr. Conley said.
Over time, a weak foot core alters your gait and can lead to falls and injuries, such as shin splints. Therefore, anyone who spends a lot of time on their feet — such as a nurse or restaurant server and people who run or walk for fitness — could benefit from adding foot strengthening exercises to their routine, said Dr. Conley.
If you want to strengthen your running game or simply protect your feet as you age, try the following five drills, listed from easiest to most challenging. They won’t take more than 12 minutes to complete in one session, but you can also sprinkle them throughout your day.
