Will My Feet Return to Their Normal Size Postpartum?

Q&A on shoe size

Emily Oster

2 min Read

My feet grew while I was pregnant: one size up; my baby is 14 months now. Will they ever go back to pre-pregnancy size? They aren’t swollen anymore, just a size longer, so all my pre-preggie shoes don’t fit. Am I wasting my time holding onto them? I suspect it was the relaxin hormone with all the tendons between the bones in my feet and toes.

—Tanya

I am sorry to report that you are indeed probably wasting your time. I looked into this in detail, and I’m afraid your question is answered by the title of this paper: “Pregnancy Leads to Lasting Changes in Foot Structure.”

The authors in this paper follow 49 women from pregnancy through five months postpartum. They find that foot size does increase during pregnancy. Interestingly, what happens is the arch gets less rigid, leading to a broadening and flattening of the foot, which often results in a need for a larger size shoe. These authors found that the foot size did not revert five months postpartum

I will say: this is only five months out! So maybe three or four years later, things will return to normal. Then again, maybe not. In the meantime, buy some nice shoes!

It’s been 27 years since my fourth and last baby was born. I have run three marathons (which can change feet!) and countless shorter road races. Went from a size 8 to a 9 or 9 1/2. Donate your too-small shoes and have fun shopping for new ones. (my new motto is “comfort over cute.”)

I’m nearly 4 years post-partum and while my feet did finally return to my usual size (was a half size up for around 3 years), I still generally need wide-width shoes now instead of my previous medium-width shoes. Possibly having to replace all of your carefully-chosen (and likely not cheap) footwear is one of the hidden costs of giving birth that no one tells you about!

I’m three years postpartum and still up a shoe size. I had to buy all new shoes. I delayed and crammed my feet into too small shoes hoping they would go back. Save yourself the pain! I’m pregnant again and terrified I’ll go up another size! I’m 5’ and wear a size 9 now. A 10 would be comical!

I received a slew of messages yesterday about a new study showing a slightly elevated risk of breast cancer with the use of hormonal IUDs. Don’t panic! The word “slightly” is key here—about 14 cases per 10,000 women.

No need to search for a new birth control method based on this alone.

💧 Is your kid drinking bathwater? Here’s the 411: It’s gross but not dangerous! Comment “Link” for my full guide to bathtime.

 A little soap or mold from toys isn’t harmful, and diluted pee is no big deal. Eating a lot of poop can make you sick, but in small amounts, it isn’t toxic.

Bottom line: Bathwater isn’t your kid’s best drink option, but don’t stress too much! Just keep an eye on them during bathtime for safety.

Ever seen a headline that makes your heart race, but when you dig deeper, the study behind it doesn’t hold up? That’s a panic headline! It’s designed to grab attention and spark fear, but the research it’s based on is often weak or irrelevant. Next time you see one, take a breath, look closer, and don’t let sensationalism get you stressed out.

We’re heading into a three-day weekend, which means a lot of you might take the opportunity to do some potty training. 

Here are some things to keep in mind:
🚽 It takes longer than three days (based on the data!)
🚽 Your child will have trouble staying dry at night.
🚽 Poop sometimes comes later than pee – this is common, you just have to work through it.
