Pain in the Arch of the Foot? Here's What It Means and What to Do
Updated October 20261 minute read
Arch pain most often comes from the plantar fascia along the bottom of the foot (plantar fasciitis) or, when it's more toward the inner ankle, the posterior tibial tendon that supports the arch. It's usually an overload or support issue, not an emergency. Supportive footwear, load management, and foot and calf strengthening typically help. Arch pain with a visibly flattening arch or that worsens with standing deserves a closer look.
What this usually means
Most likely causes. Plantar fasciitis (bottom-of-foot/heel-to-arch pain) and posterior tibial tendon dysfunction (inner-ankle-to-arch pain with arch flattening) are the leading causes. Less common causes. Foot-muscle overuse, footwear issues, or, rarely, a stress injury can cause arch pain.
What you can try at home
Wear supportive shoes, reduce a recent spike in standing or activity, and start gentle calf and foot strengthening and stretching. If your arch is visibly flattening or the inner ankle aches, get it assessed earlier rather than later.
