Mom Feet: Why Pregnancy Changes Your Feet (and What You Can Do About It)

Your belly’s growing, your boobs have officially taken on a life of their own — and now your feet are… doing things.

They’re puffy.

They ache.

They look kind of purple in weird lighting.

And none of your shoes fit anymore, but not in a cute “guess I need to buy new ones 😌” way.

Welcome to the very real, very weird world of mom feet.

If you’ve never heard of it, you’re not alone.

It’s one of those pregnancy symptoms nobody talks about until you’re ankle-deep in compression socks and Googling “do your feet grow after pregnancy” at 3am.

Don’t worry — you’re in the right place.

What does “mom feet” mean?

You’ve heard of “mom brain” and “mom jeans,” but “mom feet” is in a whole different league.

This isn’t just about end-of-day puffiness — it’s a full-body transformation that, yep, reaches your feet too.

The term “mom feet” is a catch-all for all the foot drama that can hit during pregnancy and postpartum. We’re talking:

• Swollen feet during pregnancy that make you feel like you’re smuggling water balloons in your socks
  
• Foot pain pregnancy-style that comes out of nowhere
  
• Arch collapse (fun!)
  
• Shoe sizes going up and not coming back down

And here’s the kicker: it’s not just a phase for some people.

Studies show these foot changes — especially in arch height and overall foot length — can be permanent. [1]

In fact, one study found that around 60–70% of people had lasting foot changes after pregnancy, particularly in first-time pregnancies. [2]

So if your heels suddenly feel like medieval torture devices and your go-to trainers won’t even slide on anymore?

You’re not losing it.

You’ve just got mom feet.

And you’re in very good company.

Why does pregnancy change your feet?

Here’s the deal: your body is going through a massive hormonal and structural shift, and your feet are basically caught in the crossfire.

The result? Swelling, soreness, and yes, actual size increases.

Not metaphorically, either — we’re talking a new number on the shoe box.

Here’s what’s causing all the foot drama:

• Relaxin: This hormone is meant to loosen up your joints for childbirth, but it doesn’t discriminate. It goes for your pelvis and your feet. Once those foot ligaments get stretchy, your arches can collapse — and boom, your feet spread out like a sourdough starter. Flat feet after pregnancy? Totally real.
  
• Fluid retention: Swollen feet in pregnancy? A classic. You’re carrying more blood and fluids, and gravity pulls it all down to your feet and ankles. That puffiness can make your feet look and feel bigger — even if some of it goes down after birth. Hello cankles! 👋
  
• Weight gain: Your body’s heavier. Your center of gravity’s shifted. Your feet are absorbing more stress than ever, and the constant pressure can physically change their shape.

Translation? Feet grow during pregnancy — and sometimes they don’t shrink back. [3]

What are the symptoms of mom feet?

If your feet are suddenly doing weird things, you’re probably in the mom feet zone.

Here’s what you might notice:

• Swelling: Pregnancy swollen feet are extremely common, especially in the third trimester. It’s usually harmless but annoying as hell. If they suddenly turn purple, red, or painful, check in with your doc just to be safe — purple feet in pregnancy can be a red flag for circulation issues.
  
• Pain: Foot pain in pregnancy is no joke. Whether it’s your heels, arches, or toes, the pain can hit different places depending on what’s going on. Wondering when foot pain starts in pregnancy? For many, it creeps in during the second trimester and peaks in the third.
  
• Arch collapse: AKA the reason your feet feel floppy and unsupported. Sore feet pregnancy-style often come from your arches flattening under the extra weight + hormone combo.
  
• Shoes not fitting: You didn’t just swell — you grew. A lot of people go up half a size (or more), and studies show those changes are often permanent. If you’re still waiting for your favorite boots to fit six months postpartum, it’s not you — it’s biology. [4]
  
• Feet that look… different: Flatter, longer, wider, puffier, or even purple-ish. It’s not cute, but it is common.

Do your feet ever go back to normal after pregnancy?

Ah, the million-dollar question.

The short answer: sometimes.

The long answer: depends on your body, genetics, how many pregnancies you’ve had, and how much your feet changed during pregnancy.

Some people find their feet go back to their old size (or close to it) a few months after birth.

Others? Not so much.

One study found that for many, the changes — especially arch flattening and foot length — were permanent after their first pregnancy. [5]

So if you’re still rocking a half-size up six months postpartum, congrats: you’ve officially joined the “Feet Bigger After Pregnancy” club.

It’s also not uncommon for multiple pregnancies to make changes worse — like cumulative damage.

Think: more relaxin, more weight, more pressure.

Thanks, biology.

Can you actually grow a shoe size from pregnancy?

You totally can — and many people do.

A recent study confirmed that for a significant percentage of people, pregnancy leads to permanent increases in both foot length and width. [2]

Why? Because once your foot ligaments loosen and your arch drops, your foot elongates.

And unlike swelling, that doesn’t magically snap back after birth.

For some, it’s a subtle change.

For others, it’s a full size jump — or even more if they’ve had multiple pregnancies.

And again: once that arch flattens, it rarely returns to its pre-pregnancy height. [6]

When should you worry about your pregnancy feet?

Most of the time, mom feet are annoying — but harmless.

Still, there are a few red flags worth watching for:

• Sudden, severe swelling, especially if it’s one-sided
• Feet or ankles turning purple, red, or blotchy
• Pain with numbness or tingling
• Swelling that comes with high blood pressure or blurred vision

These could be signs of more serious issues like preeclampsia or a blood clot.

If something feels off, always check in with your midwife or OB.

Trust your gut.

How to prevent mom feet

You might not be able to stop your feet from growing — but you can support them so they don’t go full pancake mode.

Here’s how to give them the love they deserve:

👣 Arch support ASAP: Get ahead of flat feet after pregnancy by wearing shoes with actual support. Yes, even around the house. Especially around the house.

👟 Rotate your shoes: Alternate footwear to reduce pressure on specific points — and avoid overusing one pair that’s already tight.

💧 Stay hydrated: It helps reduce water retention and keeps everything moving.

🧦 Compression socks: Not sexy, but very effective. They improve circulation and can seriously help with pregnancy swollen feet.

🦶 Avoid going barefoot: It feels nice, but it’s hell on already-strained arches. Keep your feet supported, even if you’re just popping to the kitchen.

🧊♨️ Ice packs and warm soaks: The combo of a cold compress followed by a warm Epsom salt soak? Literal magic for sore feet during pregnancy.

💆‍♀️ Foot massage? But be careful: A good foot massage pregnancy-style can feel divine — but make sure you’re avoiding pressure points that could (in theory) trigger labor. If you’re wondering where to avoid foot massage during pregnancy, stick with a trained prenatal massage therapist, or steer clear of the inner ankle area.

🚶‍♀️ Low-impact movement: Gentle walking or stretching can help circulation and reduce aches. Just don’t push it if your feet hurt. Pregnancy isn’t the time to suffer through “no pain no gain” vibes.

⬆️ Keep your feet elevated: Kick up those heels — literally. Elevating your feet can help with circulation and reduce swelling. Try propping them up with a pillow under your desk or chilling on the couch with your legs above heart level.

👡 Ditch the flip-flops and high heels: Instead, opt for supportive shoes (sorry, flip-flops) or insoles designed for pregnancy. This is especially important if you’re dealing with flat feet after pregnancy or mid-pregnancy arch collapse. Some people even swear by orthotic inserts.

And one more thing: don’t buy a whole new shoe wardrobe while you’re still pregnant.

Wait until a few months postpartum — your feet may still be in flux, and there’s no need to commit to a new size just yet.

So, are mom feet forever?

For some people, yes. For others, they shrink back down a bit.

But either way — this is not your fault.

Your body just performed a freaking miracle, and if the price is a slightly bigger foot… well, at least now you can finally rock those cool chunky trainers with extra toe room.

If you’re dealing with pain, swelling, or just a deep existential dread over needing to size up in shoes forever, just know: you’re not alone, and you’re definitely not the first person to whisper do your feet grow after pregnancy?? into the void.

Give your feet the care they need.

They carried you (literally) through the hardest, weirdest, most magical transformation of your life.

They deserve some love — even if they’re half a size bigger.
