How Many Shoes to Pack for a Carry-On Only Trip

Shoes are the single biggest thing that stops people fitting a trip into a carry-on. Clothes squish. Toiletries shrink. A pair of shoes is a pair of shoes: one takes up roughly the space of three or four t-shirts, and it's heavy.

So it's no surprise this is one of the most argued-about questions in packing communities. On r/onebag and r/HerOneBag, "how many shoes?" threads come up every few days and regularly pull 100 to 200+ comments. One thread literally titled "The One Shoe Travel Solution: does it exist?" got over 200 replies.

Here's what those threads actually agree on, where they split, and how to decide for your trip.

Short version: Most light packers bring one or two pairs. Wear your bulkiest pair on the plane (usually comfortable walking sneakers or trail runners in a dark, plain color). Add a second pair only if it does a different job: sandals for heat and showers, flats or loafers for a dressy evening, or waterproof boots for snow and slush. Three pairs is where carry-on packing usually falls apart. Never bring brand-new shoes.

One pair or two? Both camps have a point

Read enough of these threads and two camps show up every time.

The one-pair camp wears a pair of comfortable sneakers onto the plane and that's it. One of the most upvoted answers in a big r/onebag thread was simply: wear sneakers onto the plane and hope for the best; they'd never once needed anything else. Plenty of people report doing two weeks in Europe in a single pair of trail runners without anyone looking at their feet at dinner.

The two-pair camp has a really practical argument, though: your feet get sore in the same places if you wear the same shoes every day. On walking-heavy trips (20,000+ steps a day in Rome, Paris or Kyoto is normal), switching pairs moves the pressure points around. Several people said that alone made a huge difference by day four or five. The other reasons that kept coming up:

• Wet shoes. Step in one deep puddle or get caught in a downpour and a single pair can take a day or two to dry. One traveler's partner tried drying soaked shoes with a hotel hair dryer. It didn't really work, and the smell was a problem for the rest of the trip.
• Smell. Wearing one pair every single day for a week or more gets unpleasant, especially in heat.
• Something breaks. A sole peels off, a strap snaps. People with very large or hard-to-find sizes said this is why they always carry a backup: buying a replacement abroad isn't always possible.

Honestly, both are right. The question isn't really "one or two". It's "does the second pair do something the first one can't?" If yes, it earns its space. If it's just a spare of the same thing, most experienced packers would leave it home and, as one person put it, carry a credit card as their backup shoes.

The shoe setups people actually use

These are the combinations that come up again and again, from people who travel carry-on only:

1. One pair only. Comfortable sneakers or trail runners, worn on the plane. Best for short trips, cool weather, and trips where you won't dress up. This is the lightest setup there is.

2. Sneakers + sandals. The most popular two-pair combo by far. Wear the sneakers, pack the sandals. Sandals cover hot days, beaches, pool decks and hostel showers, and they pack nearly flat. Sport sandals with a heel strap double as light hiking shoes; flimsy flip-flops don't (several people said they're slippery on sandy paths).

3. Sneakers + flats or loafers. For trips with dinners, a wedding, a conference or a dress code. Knit or soft leather flats fold almost flat. A tip from r/HerOneBag: plain ballet flats plus small clip-on shoe jewels dress them up for an evening and take no space.

4. Boots + light sneakers (cold weather). Wear the boots on the plane (they're the bulkiest thing you own), pack thin sneakers or flats. More on winter below, and in our guide to flying with a winter coat.

5. Trail runners + sandals (city plus hiking). This is the r/onebag favorite for mixed trips. Trail runners handle day hikes and city streets; sandals handle everything warm and wet.

Which pair to wear on the plane

The rule nearly everyone repeats: wear the bulkiest, heaviest pair. It costs you nothing at the airport and frees the most space in the bag.

That matters even more on budget airlines. On Ryanair or Wizz Air the free bag is only 40 x 30 x 20 cm, and on many Asian and Australian airlines your carry-on can be weighed against a 7 kg limit. A pair of sneakers can weigh 0.7 to 1 kg; a pair of boots well over 1 kg. On your feet, that weight doesn't count. If you're close to a limit, add your bag up in the carry-on weight calculator first.

Two small extras:

• US security dropped its shoes-off rule in July 2025, but you can still be asked to take them off if something alarms, and plenty of airports abroad still want shoes in the tray. Slip-ons or quick laces save fumbling.
• If your feet swell on long flights, wear the roomier pair. Tight boots on a 10-hour flight are miserable.

Which shoes, if you're buying for a trip

Nobody can pick the perfect shoe for your feet. A moderator of a running-shoe subreddit said exactly that in one of the biggest threads: there's no one right travel shoe for everyone, only the one that works for your feet. But the advice that came up most often is useful anyway:

Break them in first. Never travel in new shoes. Blisters end city trips early. Walk a few long days in them at home, ideally wearing the backpack or carrying the bag you'll travel with.

Pick one plain color. A dark, single-color shoe with a matching sole looks intentional with jeans, chinos or a dress, and doesn't scream "gym". One HerOneBag user's take: a solid bright color reads as fashion; a white shoe with three colored stripes reads as "I forgot my other shoes."

Skip white if you'll hike. It's the classic trap: you buy white sneakers to go with dresses, wear them on a muddy trail, and they never look right with dresses again.

Trail runners usually beat hiking boots. For normal day hikes, people who hike a lot were nearly unanimous: trail runners or light hiking shoes are enough, and they're far easier to pack. Proper boots only make sense for snow, deep mud, scree or carrying heavy loads. Doing one glacier walk? Many tours rent boots.

Quick-dry often beats waterproof. Waterproof shoes are great until water comes in over the top, and then they take ages to dry and run hot in cities. Plenty of people prefer breathable shoes that dry overnight, plus a pair of waterproof socks for really wet days.

Thin canvas sneakers are the ones people regret. Flat, unpadded canvas shoes came up again and again as the pair that wrecked people's feet on cobblestones in Italy and Portugal. If you love them, bring them as the second pair, not the walking pair.

Insoles are a cheap fix. Swapping in a good insole can make a nicer-looking shoe comfortable enough for long days.

How to pack shoes in a carry-on

• Put them at the bottom, near the wheels (in a roller) or against the back panel (in a backpack). Heel-to-toe, soles facing out, is the flattest arrangement.
• Stuff them. Socks, a charger, a small pouch: the inside of a shoe is free space.
• Bag them. A thin shoe bag or a plain plastic bag keeps dirt off your clothes. A shower cap works too.
• Flatten what you can. Sandals and knit flats pack nearly flat; stand them on their sides along the edge of the bag.
• Clip-on is fine, but it counts. Some backpackers clip a second pair to the outside of the bag. That works on most full-service airlines, but on strict budget airlines anything strapped to the outside is part of the bag when it goes in the sizer. If your bag is already at the limit, the shoes go inside or on your feet.

Warm, cold or wet trips

Hot weather: sneakers plus sandals is the easy answer. Look at the forecast though. A traveler planning Scotland in late August was told by locals to drop the sandals entirely; it wouldn't be warm enough to wear them.

Cold or snowy weather: this is where carry-on packing gets hard. Bulky boots are the reason many winter trips need a bigger bag. The workable setup: wear the boots on the plane, pack one light pair for indoors or dry days, and use wool socks for warmth instead of a heavier shoe. Our New York packing list covers the boots-or-sneakers question for slushy city winters.

Rainy trips: quick-drying shoes plus waterproof socks, or one water-resistant pair you wear and one dry backup.

How many shoes is too many?

Three pairs packed in a carry-on is where people in these threads start saying, kindly, that it's not really going to work. One r/onebag commenter put it bluntly: once you're packing three pairs and wearing one, it's not going to fit a personal item, and probably not a carry-on either.

And then there's the story someone told about a family trip to Cancún, carry-on only: their daughter unpacked seven pairs of shoes from one carry-on, "like watching the clown car of carry-ons." It can be done. It just means fewer clothes.

If you're not sure the bag will close, check it before the airport: compare your bag's size with the airline in the bag size checker, and if you're flying a strict budget airline, read how strict Ryanair, easyJet and Wizz Air really are.

A quick way to decide

1. What's the most walking you'll do in a day? Over about 15,000 steps on hard pavement, lean toward two pairs you can rotate.
2. Is there a dressy event? If yes, the second pair is flats, loafers or a smart pair of leather sneakers.
3. Will it be hot, wet or snowy? Heat means sandals. Snow means boots on your feet. Rain means quick-dry plus a dry backup.
4. Can one pair cover all of it? If yes, one pair. If not, two. Almost never three.

Then build the rest of the bag around them: our guide on how many clothes to pack for one or two weeks uses the same "every item does a job" approach, and the packing list maker does the counting for you.

Mistakes people make

• Bringing brand-new shoes.
• Packing the bulky pair and wearing the light one.
• Two pairs that do the same job.
• White shoes on a hiking trip.
• Thin canvas sneakers as the only walking shoes on cobblestones.
• Hiking boots "just in case" for a city trip.
• Forgetting that shoes strapped to the outside still count in a budget airline's sizer.

Frequently asked questions

How many shoes should I pack for a one-week trip?

One or two pairs. Wear comfortable walking shoes on the plane and add a second pair only if it does a different job, such as sandals for heat and showers or flats for a dressy dinner. Three pairs rarely fit well in a carry-on.

Is one pair of shoes enough for traveling?

For many people, yes, especially on short or cool-weather trips. The main reasons to bring a second pair are sore feet from long walking days, wet weather, smell, or an event that needs dressier shoes.

Which shoes should I wear on the plane?

Your bulkiest and heaviest pair, usually sneakers, trail runners or boots. Shoes you wear don't take up space in your bag, and on airlines that weigh carry-ons they don't count toward the limit.

Are hiking boots worth packing?

Usually not for normal day hikes. Trail runners or light hiking shoes handle most trails and pack much smaller. Boots make sense for snow, deep mud, scree or heavy loads, and for those you can often wear them on the plane or rent them locally.

How do I pack shoes in a carry-on?

Put them at the bottom of the bag or along the back panel, heel to toe with the soles facing out. Stuff socks or small items inside, and keep them in a thin shoe bag or plastic bag so dirt stays off your clothes.

Can I tie shoes to the outside of my carry-on?

You can, but on strict budget airlines anything attached to the outside counts as part of the bag when it's measured. If your bag is already near the size limit, wear the shoes or pack them inside.
