Why Do Your Feet Change Size During and After Pregnancy?
It’s very common for women to notice their feet getting bigger, wider, or more uncomfortable during pregnancy. As podiatrists, we often see expectant and new mums with concerns about foot pain, swelling, or shoes no longer fitting the same.
So why does this happen — and what can you do about it? Let’s take a closer look.
1. Weight Gain and Extra Pressure
As your body changes, your feet need to support the extra load. This can:
Flatten your arches
Widen your feet
Increase your risk of foot pain and conditions such as plantar fasciitis
This is especially noticeable in the later stages of pregnancy.
2. Hormonal Changes
During pregnancy, your body produces a hormone called relaxin. This helps loosen ligaments in the pelvis to prepare for childbirth. However, relaxin also affects the ligaments in your feet, making them more flexible and leading to:
Flatter arches
Permanent changes in foot size after birth
3. Swelling (Oedema)
Swelling in the feet and ankles is very common, particularly in the third trimester. This happens due to:
Increased blood volume
Fluid retention
Pressure on veins as your uterus grows
To help reduce swelling:
Elevate your feet when possible
Stay active with gentle movement
Wear supportive, comfortable shoes that don’t rub or restrict circulation
4. Posture and Balance Changes
As your baby grows, your centre of gravity shifts forward. This often causes you to lean back for balance, which:
Puts extra pressure on your feet
Can make them feel sore and achy
Increases fatigue when walking or standing for long periods
After Pregnancy: Will Your Feet Stay Bigger?
For many women, feet remain slightly larger or wider even after giving birth. This is usually due to a combination of:
Permanent ligament changes
Flattened arches
Carrying extra load for nine months
This is completely normal — but it’s still important to take care of your feet.
Caring for Your Feet During and After Pregnancy
Here are some simple tips to keep your feet comfortable:
Wear supportive shoes with cushioning and room for swelling
Avoid flat, unsupportive footwear like thongs or flimsy sandals
Use orthotics as an aid if you develop pain when standing
Take breaks to put your feet up
Stay active with safe exercises recommended by your healthcare provider
When to See a Podiatrist
While foot changes in pregnancy are normal, you shouldn’t ignore ongoing pain or discomfort. A podiatrist can help with:
Managing plantar fasciitis, heel pain, or arch pain
Addressing swelling with footwear and support strategies
Prescribing orthotics if needed
Ensuring you stay active and mobile while caring for your baby
