Feet take the brunt of pregnancy. They carry a load that increases steadily over months, on ligaments that have deliberately been made more elastic, while the shape of the foot itself changes. Heel pain is one of the predictable results, and it is usually plantar fasciitis — but the treatment choices differ enough from the usual advice that it is worth its own page.

Why pregnancy does this

Three things happen at once, and they compound.

• Load. Weight gain across pregnancy passes through the same small attachment of the plantar fascia every step. The increase is gradual, which is precisely why it tends to present in the second and third trimesters rather than at the start.
• Ligament laxity. Hormonal changes in pregnancy increase the elasticity of ligaments throughout the body, in preparation for birth. They do not act selectively on the pelvis. A more elastic foot flattens and lengthens under load, which stretches the plantar fascia further with each step.
• Swelling. Fluid retention is normal in pregnancy, and a swollen foot changes how shoes fit and can contribute to compression of the nerve behind the inner ankle, producing burning or tingling rather than the more familiar sharp heel pain.

What it usually is

What needs attention today, not an insole

The medication question

The practical consequence is that the mechanical measures below are not merely first-line in pregnancy. They are close to the whole treatment, which makes doing them properly more important than it would otherwise be.

What actually helps

1. Wear supportive shoes indoors as well as out. The single highest-yield change, and the one most often skipped. Time spent barefoot on tile, laminate or hardwood at home is usually where the damage accumulates. A supportive house shoe or a cushioned clog worn indoors is treatment.
2. Add arch support. A flattening, lengthening arch is the core mechanism, so supporting it addresses the cause rather than the symptom. A good over-the-counter insert is enough for most people; custom devices are rarely necessary, and a foot still changing shape is not the ideal moment to have them made.
3. Go up a size, and check the width. Feet genuinely get longer and wider. Squeezing a changed foot into pre-pregnancy shoes is one of the most common reasons heel pain persists despite everything else being done well.
4. Stretch the calf and the fascia, seated. Pulling the toes back toward the shin to stretch the sole, and a straight-knee and bent-knee calf stretch, done most days. A seated version avoids the balance issues that come with a changing centre of gravity.
5. Manage the swelling. Elevate the feet when you can, keep moving rather than standing still for long stretches, and consider compression socks — worth asking your provider about, particularly if there is any additional clot risk in your history.
6. Change the surfaces you stand on. An anti-fatigue mat where you stand to cook or work removes a surprising amount of accumulated load.
7. Swap some impact for water. Swimming and water walking are close to ideal in pregnancy: they maintain fitness, the water supports the weight, and the heel gets a break.
8. Ice after a long day. Ten to fifteen minutes. It relieves symptoms and is a reasonable thing to lean on when the usual medication route is closed.

Does it go away after the baby?

Usually it improves substantially, and the load part of the problem resolves as weight normalises and ligament laxity settles over the months after delivery. Two caveats are worth setting expectations around.

First, any structural change to the arch may not reverse, so a foot that flattened somewhat may need ongoing support in a way it did not before. Second, the postpartum period is not a low-load period for feet: carrying a growing baby, pacing while feeding, and long stretches standing all continue to load the heel, often barefoot indoors. Heel pain that persists well past delivery is common, and it is worth having examined rather than waiting it out indefinitely.

Common questions

Is heel pain in pregnancy normal?

Common, certainly. Foot pain affects a large proportion of pregnancies, particularly in the later trimesters, and the heel is one of the usual sites. Common is not the same as inevitable, though — most of it responds well to footwear, support and load management, so it is not something to simply endure for months.

Can I take ibuprofen for it?

Ask your obstetric provider rather than deciding from here. Anti-inflammatories are generally avoided in pregnancy, especially in the later stages, which is exactly why the mechanical measures on this page carry more weight than they normally would. Do not assume a topical version is automatically fine either — check first.

Will custom orthotics help?

Support helps; it rarely needs to be custom. A well-chosen over-the-counter insert answers the question cheaply, and since the foot is actively changing shape, this is not the best moment to have a device moulded to it. If heel pain persists well after delivery and support is clearly helping but not enough, that is a more sensible point to consider custom.

Is the swelling in my feet something to worry about?

Gradual swelling of both feet and ankles, worse by evening and better after rest, is expected in pregnancy. What is not expected is swelling in one leg only, calf pain or tenderness, warmth or redness — or sudden swelling of the face and hands with headache or visual changes. Those need prompt medical assessment rather than a change of shoes.

Why did my shoe size change?

Because the arch lengthens and flattens under the combination of extra load and more elastic ligaments, and that change does not always reverse. It is most often reported after a first pregnancy. Continuing to wear shoes that now fit tightly is a real and very common aggravator of heel pain, so it is worth measuring rather than assuming.

Can I keep exercising?

Generally yes, and staying active is good for you — but follow the guidance your maternity team has given you for your own pregnancy. From a purely foot point of view, swapping some impact activity for swimming or water walking, in supportive shoes, is the change that tends to settle a sore heel fastest.
