Form cues

Sit with legs extended straight in front of you on the floor
Loop a band or towel around the ball of your foot
Keep your leg straight — do not bend the knee
Gently pull the band to evert the foot (sole turning outward)
Hold the stretched position for 20–30 seconds, breathing steadily
Alternate feet and perform 2–3 holds per side

The posterior tibialis stretch targets the inner ankle and calf region by everting the foot against resistance, helping address overpronation, flat feet, and inner ankle tightness.


What goes wrong — and why

Mistake

Bending the knee during the stretch

A bent knee reduces the tension on the posterior tibialis tendon, making the stretch much less effective.

Keep the leg as straight as possible throughout the hold. If hamstring tightness prevents this, use a slightly elevated position or prop the leg on a rolled towel.

Mistake

Applying too much force suddenly

Jerking the foot into eversion can irritate the delicate posterior tibialis tendon, especially in those with existing ankle issues.

Ease into the stretch gradually and build tension slowly over 2–3 seconds before settling into the hold.

Mistake

Holds too short

Holding for less than 20 seconds does not give the connective tissue enough time to respond and lengthen.

Aim for a minimum of 20–30 seconds per hold, breathing deeply to allow the tissue to relax into the stretch.


Adaptations for every level

Regression

Towel Posterior Tibialis Stretch

Using a towel or belt instead of a band provides a gentler, non-elastic resistance that is easier to control for beginners.

Variation

Standing Posterior Tibialis Stretch

Rolling the ankle inward against a band anchored to the side allows this stretch to be performed in a standing position.

Progression

Foot Eversion Exercise

Actively everting the foot against resistance (pulling the sole outward) strengthens the posterior tibialis rather than just stretching it.
