The short foot exercise trains the small muscles inside the foot: keeping your toes long and relaxed, you draw the ball of the foot toward the heel so the arch rises and the foot gets slightly shorter. Therapists use it for arch support, balance and as one part of rehab for plantar fasciitis and painful flat feet, usually alongside calf and hip strength. It is general education here, not a treatment plan; a physical therapist examines your foot and decides whether it is a useful piece of your rehab.

What does shortening the foot actually mean?
Shortening the foot means pulling the ball of the foot, especially the big toe joint, a little closer to the heel without lifting the toes or the heel, so the arch domes upward. The change is small, often only a slight rise of the arch, and that is correct.
The muscles doing it are the intrinsic foot muscles, which start and end within the foot, such as the abductor hallucis along the inner arch. They act like a living support for the arch and respond to practice the same way other muscles do. Most people struggle to find the movement at first, so it often helps to start seated with a hand guiding the foot.
How is the short foot different from towel scrunches?
Towel scrunches mainly work the long toe flexors, muscles that start in the calf and curl the toes, while the short foot targets the muscles inside the foot with the toes kept long. If your toes curl or grip during a short foot, the long muscles have taken over.
Both have a place, but they are not interchangeable. A therapist may pair the short foot with toe yoga (lifting the big toe while the small toes stay down, then the reverse) to build finer control, and with heel raises for the calf and Achilles. The arch pain in the foot page explains which kinds of arch pain tend to call for this type of work.
When is the short foot exercise used for heel and arch pain?
It is used as a supporting exercise when weak foot muscles and a collapsing arch seem to add to heel or arch pain, rather than as a stand-alone fix. For plantar fasciitis, most plans also include calf stretching, progressive loading of the plantar fascia and changes to training volume.
If the first steps out of bed are the worst, the pattern is described in heel pain in the morning, and the full condition in plantar fasciitis. Runners building toward the Carmel Marathon in April often add foot strength during winter base training, when mileage is lower and indoor time is longer.
How do you progress the short foot from sitting to single-leg standing?
Start seated, then stand on both feet, then stand on one, and finally hold the short foot while moving. Each stage adds body weight and balance demand.
| Stage | Position | What to watch |
|---|---|---|
| 1 | Seated, foot flat, a hand guiding the arch | Toes stay long and relaxed |
| 2 | Standing on both feet | Arch lifts without the foot rolling outward |
| 3 | Standing on one foot near a counter | Arch holds while balancing; see single-leg balance |
| 4 | Short foot during a mini squat or step-down | Arch and knee stay lined up as you bend |
| 5 | Short foot during a slow heel raise | Arch stays lifted as the heel rises and lowers |
How to do the short foot exercise, step by step
Do this barefoot. Start seated until you can find the movement reliably.
Sit with the foot flat
Sit on a chair with your foot flat on the floor, knee above the ankle, weight resting lightly through the heel and the ball of the foot.
Keep the toes long
Relax your toes so they lie flat and straight on the floor. They should not curl at any point.
Draw the ball of the foot back
Slide the ball of the foot, especially the big toe joint, a short way toward the heel without lifting it, so the arch rises.
Hold and breathe
Hold the lifted arch for a few seconds while breathing normally.
Relax fully
Let the foot relax completely, then repeat for the number your therapist recommended.
Stop and see a clinician if
- Pain in the heel or arch is sharp, gets worse each week, or you are limping.
- You have numbness, burning or tingling in the sole of the foot.
- Foot pain began suddenly during running and the bone is tender to touch, which can suggest a stress fracture.
- You have diabetes and notice a wound, a color change or a change in foot shape.
If you think it is an emergency, call 911.
