If you’re hypermobile, foot and ankle instability may or may not look obvious.
Here are signs and symptoms I see in my clinic when someone is lacking foot/ankle stability:
1. Plantar fasciitis
When the midfoot lacks controlled stability, the plantar fascia absorbs more load than it should.
2. Needing very supportive shoes or orthotics to function
The need for external support usually indicates intrinsic foot control deficits.
3. Knee or low back pain that never fully resolves
The knee often pays for poor foot organization. If the foot collapses or shifts unpredictably, the knee absorbs the torque.
4. Arch fatigue or calf tightness by the end of the day
Calves often overwork to create stability when the foot isn’t distributing load efficiently. Arches may feel overworked or overtired.
5. Feeling unstable on uneven ground
History of falls, avoiding different surfaces, avoiding barefoot, always using upper extremity assist when going up and down stairs all make me look deeper into foot and ankle stability.
6. Repeated ankle sprains or a history of rolling your ankles.
Once the joint has moved beyond your controllable range, you may initially have several “ankle rolling” incidences. This can persist or evolve into “stiff ankles” as the years pass.
In hypermobility, there may be adaptive stiffness, but the issue usually isn’t lack of movement but rather the difference between available range and controllable range.
Optimally, we want a pliable but stable foot/ankle complex to feel and move well.
