What Size Booties Should I Get? What I Learned After Buying the Wrong Size
The first thing my daughter did when she pulled herself up on the coffee table was reach for her feet. She was nine months old, and the concept of her own toes was still new. So when my mom asked what to get her for winter, I said booties. Not shoes, not sneakers. Soft-soled booties that would keep her feet warm without fighting the learning-to-walk process.
My mom, ever practical, asked the question that sent me into a spiral: “What size should I get?”
I had no idea.
I looked at the package of booties we already had at home. They said “0–6 months” and were covered in tiny foxes. My daughter wore them once, and they slid off mid-car-ride. We found one behind the back seat weeks later, dusty and too small even to donate. I assumed booties were like socks: cute, disposable, not worth overthinking. But watching her try to stand, I realized they actually mattered. Her toes curled under when she tried to walk on the hardwood floor in her footed pajamas. She needed something on her feet, but it couldn’t be too tight or too loose.
So I did what any tired parent does. I texted three friends, checked two Facebook groups, and ended up at the store holding a measuring device shaped like a shoe. The sales associate looked at me like I was the first person ever to ask this question in her store.
“Just feel their toes,” she said. “You want a thumb’s width between the longest toe and the end of the shoe. And you don’t need them to walk in them all day. These are for warmth, not for training.”
It sounded simple, but it wasn’t. Because my daughter’s feet were fat on top and narrow at the heel. The booties that fit her width were too long. The ones that fit her length squeezed her chubby instep. I ordered three sizes online and returned two. I started measuring her feet at the end of every week, because at that age, feet grow faster than you expect. One week she was a size 2. Three weeks later, the same booties left red marks on her ankles.
Here’s what I eventually learned.
Don’t buy based on age labels. Those labels are rough guesses from manufacturers, and they vary wildly between brands. A “6–12 months” bootie from one company is a “3–6 months” somewhere else. Measure the foot. Put the foot flat on a piece of paper, mark the longest toe and the heel, and measure the distance. That gives you the foot length in centimeters. Most baby shoe brands list sizes in centimeters on their websites, which is more reliable than age ranges.
The thumb’s width rule works. If you press your thumb on the top of the bootie right at the toe area, you should feel a little space. Not a lot. If you can pinch the fabric at the toe, they’re too big. If you can’t feel the toe at all, they’re too tight. But remember, booties are soft. They’re not like sneakers. A snug fit is okay, as long as there’s no pressure.
Check width too. I never thought about width until my daughter started getting red lines on the sides of her feet. Some kids have narrow heels and wide forefeet. If the bootie is too narrow around the ball of the foot, the toes get squeezed together, and that can affect balance when they’re just starting to stand. Look for booties with stretchy sides or a tie or snap around the ankle so the fit adjusts.
When my daughter started standing at the coffee table, she didn’t need hard-soled shoes. In fact, pediatric development folks generally say barefoot is best for balance and feeling the ground. But that doesn’t work when it’s cold or when we’re walking through a parking lot. That’s where booties come in. They protect the foot but still let the toes flex. Think of them as wearable socks, not as shoes.
The trickier part was figuring out when to put them on and when to leave her barefoot. I started making an effort to let her go barefoot around the house as much as possible, especially while she was pulling up and cruising. The booties were only for outings or cold tile. When she was wearing them, I’d check her toes every few minutes. If she started tugging at them or scooting them off, that wasn’t a behavior problem. That was a fit problem.
One thing I didn’t expect: the bootie size question came up again at daycare, but not the way I thought. Her teacher mentioned that some kids come in with shoes that are still in the box, too stiff, or clearly too small. One little boy had sneakers that were a size too big, and he kept tripping. The teacher’s advice was simple: bring two pairs if you can, one for indoors and one for outdoors. Indoors, booties or socks only. Outdoors, a flexible sole that lets the foot bend naturally.
That made sense to me. Booties are indoor shoes, really. They keep warmth without being heavy. But if you’re buying them, buy them just a little big, not a lot big. The “maybe they’ll grow into them” instinct pushes all of us to size up. My mom ended up getting the next size up, and my daughter’s feet swam in them. Her toes pushed against the front when she tried to stand, which made her curl her toes under more. She was compensating, trying to grip the floor through the bootie. It was safer to just get the right size now and accept that we’d need to buy another pair in a month or two.
The last thing I figured out was about materials. Canvas and leather are okay. Anything shiny or slippery, no. And avoid booties with laces or buckles if you’re putting them on someone who wants to eat their feet. We had a pair with a little leather strap, and my daughter managed to get it off within ten minutes and chew on the buckle. Softer, slip-on styles ended up being what we actually used.
We still have that pair of fox booties, now too small, sitting in a drawer with other things she’s outgrown. I don’t have a perfect system. I measure her feet every two weeks. I check for red marks. I keep a pair in the diaper bag and another in the car. When she suddenly stops walking around the house and starts crawling again, I check the booties first.
The honest answer to “what size booties should I get” is: measure the foot, add about half a centimeter, and be prepared to do it again sooner than you think. But if we’re talking about the moment when you’re holding a shoe measuring device in the middle of a store with a squirming toddler under your arm, what I’d really say is: get the pair that doesn’t leave marks when you take them off. Because your kid will outgrow them either way, but at least the ones that fit now mean she can use her toes to figure out how to stand.
