Baby's first shoes: when, which, and how they should fit

There is no age for it, only a sign: your baby walks outside without holding your hand, on ground that needs a barrier. First steps come at about 8 to 18 months, and walking outside often follows weeks later, because a baby who walks across the living room still rides in the stroller or sits on your arm for most of an outing.

It is easy to think a wobbly cruising baby needs high-⁠top leather shoes to hold the ankles straight. The opposite is true. Babies balance by spreading the toes and feeling the floor beneath them, and a stiff sole gets in the way of both. At home, bare feet or socks with grip dots give little feet the freedom to grip and build muscle.

Crib shoes look adorable on a shelf, but they are fashion, not gear. The same goes for outings where your baby stays strapped in the stroller or carrier. In a stroller, rigid baby shoes mostly serve one purpose: getting kicked off and lost on the street. Stick with soft socks or baby booties until your baby actually stands on outdoor ground.

The first walks outside need very little. On dry grass or cool sand, bare feet are fine, and good for the foot, because uneven ground is where balance gets built. On a smooth, dry path, a soft leather pre-⁠walker shoe protects the skin without weighing the foot down, and a baby who crawls at the playground gets the same soft shoes, so the tops of the feet stay unscraped. Closed first shoes with a rubber sole start where the ground does: sidewalks, gravel, wood chips, and anything wet or cold.

Outside, the temperature narrows the choice, but the surface settles it. Four kinds cover the year, and a toddler needs two at a time: the pair for the season, and the boots for its wet days.

In direct sun, asphalt, dark rubber playground surfacing, a slide and dry sand get far hotter than the air, hot enough to burn even on a day that doesn't feel hot, and a toddler standing on a hot surface doesn't know to step off it the way a hand pulls back. So before the shoes come off at the sandbox, put your hand flat on the ground for a few seconds. If it feels hot to you, it is too hot for your baby's bare skin, and the sandals stay on.

Once the days are hot, closed-⁠toe sandals take over from first shoes: air reaches the foot, and the sole still keeps the heat and the grit out. For a new walker, the back of the sandal matters more than the front.

Toddlers do not dodge puddles. They head straight for them. A leather or canvas first shoe soaks through in a few minutes of wet grass, and a wet sock makes a cold foot even on a mild day. On wet days, rain boots replace the first shoes, always over socks, because bare feet sweat and slide around in rubber. Once the ground is cold, lined winter boots do the wet days too.

Watch the weight of the boots you buy. Tall, stiff rubber boots feel like weights on the ankles of a child who learned to walk a month ago, and the tripping starts. Light ankle-⁠high boots with a thin sole that bends at the toes let a new walker take normal steps, and they keep out every puddle a toddler can reach at this age.

Wet boots come off at the door. Strip damp socks right away, pull the insoles out and leave the boots open to dry at room temperature before the next outing. On the way, a dry pair of socks in the stroller basket is the cheapest fix there is, and a small wet bag keeps muddy boots away from the clean diaper bag. The raincoat and rain pants that go with the boots are in dressing a baby for rain.

When the air cools down, remember the sock trap. Squeezing thick winter socks into a snug first shoe presses the toes together and cuts off blood flow. That actually makes small feet colder, not warmer. One pair of warm socks inside a boot with room to wiggle the toes keeps a foot warmer than two pairs jammed in, because the warmth sits in the air the knit holds.

Lined winter boots take over from first shoes on cold ground, because the cold comes straight up through a thin everyday sole. Buy them with the winter socks on. To see the room inside, pull the insole or the felt liner out and stand your toddler on it in those socks: about a finger-⁠width should show past the longest toe. Half a size up from the shoe size is usually right, and more than a whole size up turns a boot into something a new walker trips over.

A toddler who walks for ten minutes and then rides the rest of the way stops making heat in the feet the moment the walking stops. For the ride home, the feet go into the footmuff, boots off if they are wet, and the toes get a check at the door (dressing a baby for cold weather).

Buying first shoes is usually an exercise in patience. Babies often curl the toes into tight fists the second a shoe touches the foot. Relax the foot by stroking the sole, open the fastening wide, and slip the heel in flat. Try shoes on while your baby is standing, in the socks that will go in them, because a foot gets longer and wider under body weight.

Three things tell you the pair fits. With your baby standing, about an adult finger-⁠width, 6⁠–⁠10 mm (0.25⁠–⁠0.4 in), of room shows in front of the longest toe. The heel stays in the shoe when your baby rises onto tiptoe. And the sole bends easily at the ball of the foot when you fold the toe up with one hand: if you have to muscle it, your baby cannot bend it either.

Baby feet grow at an astonishing speed. A first pair usually lasts two to three months, so check the fit about once a month, and sooner if a pair that was fine last week is suddenly refused. A shoe that felt roomy in September can start pinching toes before Halloween. Skip hand-⁠me-⁠downs that have lost their shape or worn down at the heel, because a sole shaped by another child's stride tips a new walker off balance. A soft pre-⁠walker that was barely worn is fine to pass on.
