Double Jointed Ankles: What Extra Range Really Costs You

Double jointed ankles are not a medical term, but most people who use the phrase mean something specific: an ankle that bends further than other people's, that rolls outward easily, and that feels vaguely untrustworthy on a kerb or a stony path. The everyday name for that is a loose or lax ankle. The underlying reason is usually that your ligaments are a little more elastic than average.

This is common enough to be unremarkable. Among university students in one published cohort, roughly 12.5% cleared a strict threshold for generalised joint hypermobility (PeerJ, 2019). Being bendy is a variation, not a diagnosis, and for many people it never causes a single problem.

Signs you have double jointed ankles

The ankle rolls easily and often. Repeated small rolls on flat pavement, kerbs and gentle slopes are the most reliable sign. Most people roll an ankle occasionally. Some ankles do it monthly.

You can point the foot unusually far. Extra range into pointing, or a foot that can turn inward much further than a friend's, suggests ligaments with more give.

Uneven ground feels unreliable. Grass, gravel, sand and dark stairs all feel harder than they should, and you find yourself watching your feet.

Standing still aches more than walking. Loose joints rely on muscle rather than ligament to stay put, and muscles tire. Queuing hurts more than a walk, which sounds backwards but is very typical.

Other joints are bendy too. Elbows that hyperextend, thumbs that reach the forearm and knees that bow backwards usually travel together. Our double jointed elbows compared with normal range covers that side, and hypermobile feet looks further down the same chain.

What extra range actually costs

The thing worth understanding is that ligaments are not just straps. They are dense with nerve endings, and a fair amount of what you know about where your foot is comes from the tension in them. A ligament with more give sends a weaker and later signal.

That is the real cost of a loose ankle, and it is not weakness. You get less warning. By the time the ankle tells your nervous system that it has started to roll, it has already rolled further than a tighter ankle would have. The muscles that would catch it are working from late information. Our Feldypedia entry on hypermobility and joint instability goes into how that plays out across the body.

This is why the usual flexibility advice is exactly backwards here. You do not need more range. You have range to spare. What you need is better information and better timing, and that is a learning problem rather than a stretching one. The Feldenkrais Method® is built around precisely this: slow, small movements done with close attention, so the nervous system gets a clearer map of where the foot is and what it is doing.

What helps a loose ankle

Stop stretching it. This is the single most useful change for most bendy ankles, and it is also the hardest to accept, because stretching feels productive and the extra range is easy to reach. Nothing about a loose ankle improves with more give.

Then build the sensing. Barefoot weight shifting while standing still, slow rises onto the toes and back down, standing on one leg near a kitchen counter, and walking deliberately over slightly uneven ground all teach the ankle to report earlier and the muscles to answer sooner. Keep every session short and accurate rather than long and tired. Our exercises for hypermobility put this into a sequence you can follow.

Footwear matters more than it does for other people. A shoe with a firm heel counter and a sole that does not twist easily gives an unstable ankle something to work against. Save the soft flexible shoes for flat, predictable ground.

A word on the rest. Clinical care sits alongside all of this and nothing here replaces it: a physiotherapist can grade the strengthening properly, and repeated giving way or widespread joint pain deserves a medical opinion. Yoga and Pilates operate by a different mechanism again, through held shapes and controlled repetition, and Pilates in particular suits many hypermobile people well, provided the teacher understands that the goal is control rather than depth. Feldy works on the sensing side of the same problem.

Find where to start

If your ankles have rolled since you were a teenager and every piece of advice you have been given was about flexibility, you have probably been solving the wrong problem. The Feldy program for hypermobility starts from stability instead.

Common Questions about double jointed ankles (FAQ)

Are double jointed ankles dangerous?

Not in themselves. Plenty of people move through life with extra ankle range and never think about it. The practical risks are a higher chance of rolling the ankle on uneven ground and more aching after long standing. Get medical advice if you also bruise easily, have stretchy skin, dislocate joints, or have widespread joint pain, since those together deserve a proper look.

How often should I practise for ankle stability?

A few minutes on most days works better than a long weekly session. Balance and control are learned skills, and skills respond to frequency. Keep each session short enough that you stay accurate rather than tired, because sloppy repetition teaches sloppiness.

How long until unstable ankles feel steadier?

People often notice better footing on uneven ground within three to six weeks of regular short practice, because the change is largely one of coordination rather than tissue. Lasting confidence on stairs and slopes usually takes a few months. Ankles that keep giving way despite consistent practice should be assessed.

How is this different from ankle strengthening from a physiotherapist?

A physiotherapist prescribes graded strengthening and balance work, often with bands and single leg drills, and that has a good evidence base for unstable ankles. Movement awareness adds the sensing side: knowing exactly where your foot is without looking, which is the part hypermobile joints most reliably lack. Doing both is a sensible plan.

What is the best exercise for double jointed ankles?

The best starting exercise is slow, barefoot weight shifting while standing. Move your weight gently forward, back and side to side within a small range, feeling which parts of the foot take the load. It builds the sensing and control that a loose ankle actually lacks, without any risk of overstretching.

What exercises should I avoid with double jointed ankles?

Avoid deep ankle stretches, sitting back on your heels with the feet pointed hard, and anything that shows off the extra range, since none of it adds anything you need. Be careful with fast plyometric jumping, uneven trail running and unsupported high impact classes until your control is reliable. Standing still for long periods often aches more than moving does.
