Also called: Restricted ankle dorsiflexion; stiff ankles
Exercise is the main treatment
Stretch
Strength
Massage
Squat down and the heels come up, the back rounds or the arches collapse. The limitation is almost always ankle range: the knee cannot travel forward over the foot, so the body finds the movement somewhere else - which is why this shows up as knee, back or foot pain.
How common: Extremely common, especially after any ankle sprain and in habitual heel wearers; a limitation in a large share of people who squat
What it is
Squatting requires the shin to travel forward over the foot - ankle dorsiflexion. If that range is not available, the body has three options and it takes all of them: lift the heel, round the lower back, or let the arch collapse inward. Each is a different problem downstream.
The restriction is usually either the joint capsule at the front of the ankle or a short soleus, the deep calf muscle that limits dorsiflexion specifically when the knee is bent. Which one it is changes what fixes it, and there is a simple distinction: if the range improves with the knee bent, it is more capsular; if it is worst with the knee bent, the soleus is the limiter.
What it feels like
- Heels lifting off the floor as you go down, and having to hold on to something
- Falling backwards at the bottom of a squat
- A pinching or blocked feeling at the front of the ankle rather than a stretch at the back
- The lower back rounding at the bottom, which you may only notice from a video
- Knees falling inward and arches flattening as you descend
What causes it
Most people have more than one of these at once, and they feed each other. Read the
list looking for the two or three that sound like your week rather than for the one
true answer — the ones that describe you are the ones worth acting on.
- Ankle joint capsule stiffness
- The talus has to glide backwards in the ankle mortise as the shin comes forward. A stiff capsule at the front of the joint blocks that glide, producing a pinching endpoint at the front of the ankle rather than a stretch at the back.
- A short soleus
- The deep calf muscle crosses only the ankle, not the knee, so it limits dorsiflexion most when the knee is bent - exactly the squat position. It responds to bent-knee calf stretching, which most people never do.
- A short gastrocnemius
- The superficial calf crosses the knee as well, so it limits dorsiflexion most with the leg straight. It contributes to the same problem in a different position.
- A previous ankle sprain
- Ankle sprains reliably leave reduced dorsiflexion, often years later, and often on a leg the person no longer thinks about. It is one of the most consistent findings after a sprain.
- Heeled shoes
- Any raised heel holds the ankle in plantarflexion for hours a day. Worn for years, the tissue and the joint adapt to that shortened position - and a running shoe has more of a heel than most people realise.
- Weak or uncontrolled hips
- Not all of it is the ankle. Weak glutes let the knee drift inward, which reduces the effective dorsiflexion available and makes the ankle look like the culprit.
- Never going near the range
- A deep squat is not required by any part of modern life. Chairs, beds and raised seats mean the range is unused for decades, and unused range is withdrawn.
- Simply not knowing how to squat
- Some of this is a skill. Where to put the weight, how far apart the feet go, how much to turn them out - these are learnable and a surprising amount of apparent stiffness is technique.
Who tends to get it
- Anyone with a history of ankle sprains, on the sprained side
- Habitual heeled shoe wearers
- Runners, in whom calf tightness is close to universal
- Desk workers who never go near a deep squat
- Anyone with knee pain, since restricted ankles are a common upstream cause
What makes it worse, and what settles it
Makes it worse
- Only ever stretching the calf with the knee straight, which misses the soleus
- Squatting on a raised heel permanently, which works around it and never changes it
- Forcing a deep squat with a rounded back, which trades the ankle problem for a spinal one
- Continuing to wear a raised heel all day
- Working only on the ankle when the hip is also contributing
Settles it
- Bent-knee calf stretching, which targets the soleus specifically
- Knee-to-wall ankle mobilisation, which addresses the joint glide rather than the muscle
- Practising the squat itself, holding on to something, going only as deep as is clean
- Glute strengthening so the knee tracks properly and the range is usable
- Massage and soft tissue work on the calf to reduce tone before mobilising
What actually helps
The short version: Restricted talocrural dorsiflexion from joint capsule stiffness or a short soleus. The knee cannot travel forward, so the body finds range by lifting the heel, rounding the low back or collapsing the arch - which is why this shows up as knee, back or foot pain
Strength work: Legs: Calves: Soleus; Legs: Calves: Gastrocnemius; Legs: Calves: Tibialis Anterior; Feet, Toes, Ankles - loaded calf work through full dorsiflexion
Stretching: Legs: Calves; Legs: Calves: Soleus - knee-bent for soleus, knee-straight for gastrocnemius, and most people only ever do the straight one; Feet, Toes, Ankles
Massage: Legs: Calves; Massage Stick; Feet, Toes, Ankles
Also worth doing: Knee-to-wall test to measure it and to track it; a heel-raised shoe is a workaround, not a fix
What the evidence says: One of the highest-leverage restrictions in the body: it is upstream of knee pain, plantar heel pain, flat feet and squat mechanics. Knee-bent (soleus) work is the part that matters and the part everyone skips.

Sudden loss of dorsiflexion with pain and swelling after injury needs fracture assessment
And whatever the body part: chest pain or unusual breathlessness on
exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and
unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or
one calf that is swollen, warm and painful. Any of those, stop and get assessed.
How it usually goes
Ankle range responds well - most people gain measurable dorsiflexion within four to six weeks of daily work, and the effect on squatting, stairs and knee comfort is usually noticeable before the range measurement changes much. Capsular restriction responds to mobilisation more than to stretching, so if weeks of calf stretching have changed nothing, that distinction is the thing to try next. It relapses if the raised heels and the disuse go back to normal.
Prevalence basis: Ankle range-of-motion screening studies
Others the same routine covers
These share the Getting Down & Up: Squat, Kneel & Floor routine, so the work is the same. If one of them also
sounds like you, that is a reason to expect more from it, not less.
