7 Reasons Mums All Over the UK Are Quietly Ditching Their Pre-Baby Shoes

By Kendra Williams • 6 min read

If your feet ache by bedtime and none of your old shoes feel right anymore, you're about to find out it isn't in your head — and it isn't just "being on your feet all day," either.

There's a piece of research that should be handed out with the red book. Scientists at the University of Iowa measured women's feet at the start of pregnancy and again five months after birth, and published the results in a medical journal. What they found: in roughly 60–70% of women, feet came out of pregnancy measurably longer and wider, with a flattened arch — and five months later, the change hadn't reversed. For most women, it never fully does.

Two in three mums. Different feet. Almost none of us told.

Once you know that, a lot of small daily miseries suddenly make sense. Here are the seven reasons thousands of UK mums are clearing out their pre-baby shoe collection — and what they're wearing instead.

1. Their feet are genuinely a different shape now — and their shoes aren't

During pregnancy, the body releases a hormone called relaxin, which loosens ligaments so the pelvis can adapt for birth. But relaxin doesn't stop at the pelvis. It loosens the 100-plus ligaments in the feet at the exact moment they're carrying more weight than ever before. The arch flattens under the load, the foot spreads, and — because ligaments aren't muscles — it doesn't simply ping back afterwards.

The result: a wider, flatter foot living in a wardrobe of shoes bought for a narrower one. Every pointed flat and tapered trainer presses the toes together for hours a day. The ache isn't mysterious. It's mechanical.

2. Sizing up didn't work

Worn: 0 times since 2023.

Most mums try the obvious fix first: buy the usual shoes, one size bigger. It almost never helps — and there's a simple reason. UK shoe sizes measure length, but the post-pregnancy change is mostly about width and arch. A longer narrow shoe is still a narrow shoe: the toes stay squashed, the heel starts slipping, and now the stairs are a hazard too.

What actually fits a post-baby foot is a different shape of shoe — widest at the toes, where the foot is now widest.

3. The end-of-day ache turned out to be optional

Ask around at any school gate and you'll hear the same thing: throbbing along the inside of the foot, burning under the ball of the foot, the ritual of taking shoes off the second the front door shuts. Most mums file it under "part of the job."

The mums who've switched to wide, foot-shaped shoes report something almost annoying in its simplicity: when the toes have room to spread and the weight sits evenly across a flat sole, the all-day squeeze stops — and with it, for many, the evening ache. Not a miracle. Just shoes that match the foot.

4. Cushioned trainers were quietly making things worse

This is the counterintuitive one. The instinct after pregnancy is more cushioning — thick, soft, pillowy soles. But there are two problems.

First, almost all cushioned trainers have a raised heel, which tips the body's weight forward onto the ball of the foot — often the exact spot that already hurts. Second, when a thick sole does all the work, the small muscles that support the arch are never asked to do their job. For a foot whose ligaments have already been loosened by pregnancy, that's the wrong direction: the support system weakens just when it's needed most.

A flat, flexible sole does the opposite — it lets the foot bend, grip and gradually strengthen with every ordinary step.

5. The school run became free foot physio

Here's the part busy mums like most. Strengthening post-pregnancy feet doesn't require exercises, appointments or ten spare minutes that don't exist. In flexible, zero-drop shoes, every normal step gently works the foot's own muscles — the school run, the supermarket, the soft-play marathon all quietly count.

Physios have long recommended foot-strengthening for exactly this reason; barefoot-style shoes simply build it into the day. No routine to remember. Nothing extra to do. It happens while life happens.

6. They stopped having to choose between comfort and looking normal

For years, "comfort shoes" meant surrendering: orthopaedic styles, gym-only trainers, or the dreaded sensible shoe. The newer generation of barefoot trainers looks like — trainers. Clean lines, everyday colours, the kind of shoe that works with jeans on the school run and doesn't announce itself.

The Valessi Meadow (pictured) is a good example of the shift: wide toe box and flat flexible sole hidden inside an ordinary smart white-and-rose trainer. The technology is invisible. Only the feet know.

Same foot, three years post-baby — narrow flat vs the Meadow's wide toe box.

7. The risk of trying is basically zero now

The final reason so many mums are making the switch: the gamble has been removed. Valessi currently offers:

• 40% off for new customers
• A 30-day "school run guarantee" — wear them every day for a month, and if your feet don't feel better, send them back worn for a full refund

That last part matters. Shoes are personal, feet doubly so. A guarantee that lets you actually live in them for a month — school runs, park trips, the lot — means the only thing at risk is the ache you already have.

Size 5 → size 6 wide. Two minutes, one biro.

The bottom line

Your feet carried you through pregnancy and every day since — usually with a child, a car seat, or four bags of shopping added on. For most mums, they changed shape doing it. That's not a flaw to squeeze back into old shoes; it's just a fact nobody mentioned.

The fix is genuinely unglamorous: shoes shaped like your actual foot, flat enough to spread your weight, flexible enough to let your feet get strong again. Everything else — the ache, the shoe graveyard in the wardrobe, the secret shoe removal at weddings — tends to sort itself out from there.
