Finding your perfect fit

Our merino fabric expertly stretches to fit the contours of your foot. Due to this adaptability, we only offer whole sizes.

All sizes are US-based

First, choose your style.



Let us help you find your perfect fit.

What US size do you usually wear?

Our current sizes run from US Women's 5 to Men's 14. If you're outside of this range, please contact customer service so we can get a sense of how many of our small and big footed friends are eager to try Allbirds - there's always a chance we'll be able to add to the size range in the future.

Your Allbirds are built to travel

So in all likelihood, they will get pretty dirty.
Don’t worry, we thought of that.

Cleaning your Allbirds

  • Remove the insoles and laces, and brush off excess dirt with a towel or soft brush.
  • Throw the shoes in the washing machine on wool/delicates cycle (cold water). We recommend using a linen bag and washing the insoles by hand for best results.
  • Do NOT tumble dry – air dry your Allbirds like the good ol’ days.
  • Good as new! Reinsert the insole and laces and get on with your day.

Replace your insoles

Feet stink. It’s a fact of life, and usually absorbent insoles are the main culprit of a smelly shoe. We want you to wear your Allbirds for a long, long time, so we offer premium replacement insoles -- high cushion, lined with our merino fabric -- at a fraction of other replacement insoles on the market. These insoles are designed for plush comfort, made with vegetable oil to put the spring back in your step.


Frequently Asked Questions


Do you offer half sizes?

Our shoes come in whole sizes only. That being said, Allbirds are made of a super soft merino upper that makes them feel equal parts snug and stretchy. If you typically wear a half size, we suggest that you size up in both the Wool Runners and Wool Loungers.

I have a wide foot; will Allbirds fit well?

Our shoes are all medium width. Even if your feet tend to run wider, you might be shocked at how well our merino textile stretches to your foot. We have numerous wide-footed customers who are quite happy (including our co-founder Tim). If you wear a half size, try the size up for some extra wiggle room!

Can I remove an Allbirds insole?

Sure can. If your feet have special requirements, replace our insoles with your orthotics and give the gift of our super soft merino insoles to a friend. If you wear a half size, we suggest that you size up.

I love your insoles! Where can I get replacements?

Right here. Glad you love them as much as we do.

Aren't wool shoes hot?

Just like the wool on a merino sheep, our shoes keep you warm in the cold, and cool in the heat. This thermoregulation is a natural property of merino. For an extra layer of warmth on cooler days, try wearing thin socks.

What about when they get wet?

Merino wool can absorb up to 35% of its weight in water, which is how it wicks sweat away from your foot so effectively. When wet, superfine merino still regulates temperature, so your shoes won’t feel sloshy and won’t leave you smelling like a wet dog...or sheep! If you happen to be a weather reporter considering wearing Allbirds while covering the next hurricane, we humbly suggest using rain boots.

Why hasn’t merino been used in shoes before?

Merino wool is so fine -- ours is less than 17 micron (that’s about 20% of the average diameter of human hair) -- that it has historically been difficult to make a fabric strong enough for shoes. But we found a way.

Do your shoes only come in two styles?

We have a number of exciting products and novel natural materials in our design pipeline. Sign up for email updates at the bottom of the page to be kept up to speed when we launch new products.

What is in your outsole and why is it so cushy?

Our proprietary blend of EVA low-density foam is mixed with rubber to make a light, but highly durable outsole. Our injection molding process also helps reduce waste. We love finding new ways to make products that are better for you and the world. Plus, better outsole friction means no slipping, just floatin’.

What’s up with the box?

Because we sell directly to you via our website, we designed a patent pending box that is a shipping box and shoebox all in one. It uses about 40% less material, is made of 95% recycled cardboard, and is 100% recyclable – plus, we think it’s pretty good looking.

Will you ever have more sizes?

We have expanded the size range offered in our Classic colors to include women’s 5 and men’s 14. Our shoes all have a unisex fit, so women with larger feet and men with smaller feet have even more options to choose from.

Our women’s sizes run about 1.5 sizes shorter than our men’s sizes. For example, if you’re a women’s 11.5, the men’s 10 should be a perfect fit.

For men: If you typically wear a men’s 7, you can try the women’s 9.

If you run smaller than a women’s 5 or larger than a men’s 14 and want to be able to treat your feet, let us know at We always love to hear from you!

How many sheep does it take to make a Wool Runner?

One sheep’s painlessly shorn coat produces enough wool to make about 20 pairs of shoes. We get sustainable, soft, and natural material, and they get a haircut!

What if I’m allergic to wool?

Turns out that most people aren’t actually allergic to wool! The coarse fibers on that wool sweater you bought in 1998 will often irritate your skin, creating the sensation of an atopic allergy. Our proprietary superfine merino is made from fibers that are about 20% of the diameter of the average human hair, and are incredibly soft. Can’t know for sure, but we’d venture to guess that they won’t irritate your skin. In the off chance that they do, send them back within 30 days for a full refund, no questions asked.

The pair I want is sold out!

Because we are exclusively a direct to consumer brand, planning gets tricky sometimes. Sign up for our sparingly sent email updates (bottom of page) and we'll let you know when we release new colors.

Our Limited Edition colors are refreshed seasonally, so once sold out they are gone for good. We'll always have our Classic colors, so even if your size is unavailable you can place an order on backorder!

I don't see the color I had my eye on. Where is it?

If the color you've been eyeing isn't available for purchase, this color is sold out indefinitely. All colors that are available for purchase are listed on our product pages. We're constantly working to release new colors that reflect the season, so hopefully we'll have a new color you love soon!

When will you release new colors?

We refresh our Limited Edition colors multiple times per year. Be sure to sign up for our mailing list to be notified of new released as soon as they come out!

Can I buy additional laces?

Yes, here! Check back soon if your favorite set is sold out.

How do I wash my Allbirds?

If your shoes accompany you on a wild adventure and start to feel a little less than fresh, throw them in the washing machine on the wool or gentle cycle. Be sure to remove the insoles and laces. You can use gentle detergent and a wash bag for the best results.

Don’t forget to air dry like in the good ol' days - and whatever you do, no dryer!

Are Wool Runners actually meant for running? Loungers for lounging?!

Though called the Wool Runner, our lace-up style is better used for seeing a city than running a marathon. Similarly, the Wool Lounger is not meant for lounging. From red eyes to restaurant openings, they’ll take you seamlessly through your day into night.


What is the status of my order?

You will receive a shipment notification email once your order is en route to you! If you are having trouble tracking your order, email

If you’re just getting cold feet, hold on a minute -- we think you’ll love them and if you don’t, you can always send them back for free within 30 days of purchase.

How much is shipping?

We offer free shipping, returns and exchanges in the US, New Zealand and Australia.

Where do you ship?

We currently ship to the US, New Zealand and Australia.

We are hoping to expand to other regions and countries in the future! In the meantime, perhaps this is the perfect excuse for a stateside visit or a vacation down under.

What is your return policy?

We offer a 30-day trial period; you can return your shoes with no questions asked, even if you have worn them out in the wild.

Can I expedite my order?

As of now we only offer 2-5 business complimentary shipping. Orders shipped to urban addresses typically take closer to 2-3 business days to arrive!

How do you ship?

All orders are shipped during business days via Courier Post from our distribution center in Auckland. Orders placed after 12pm on Friday and through the weekend will be dispatched Monday morning.

How do I make a return?

You order will arrive with an included return label. You can either drop off your shoes (in the original or any box) at your local Post Office, or call 0800 COURIER (0800 2687437).

How do I make a gift exchange?

Let us know at The more information you provide about the gift giver, the better! Once we know the order number and customer information from the original order we can request that a pre-paid return label be sent your way.

Please provide the size and color of the new pair you would like for the exchange. Let us know the best shipping address and we can send the new pair to you directly!

What do you do with used shoes that are returned?

We never resell shoes that have been scuffed or worn outside, no matter how lightly. We have partnered with Soles4Souls, and we donate used shoes to them for distribution to people in need.


How are your sheep treated?

We buy only the finest merino wool from New Zealand (our founder, Tim’s, homeland). All our wool is ZQ Merino certified, which ensures that our merino comes from the most humanely treated sheep in the world. Unlike most sheep farms in Australia and China, our farmers are prohibited from using the harmful practice of mulesing.

Our sheep lead happy lives, with glorious hilly views to boot. Visit the ZQ Merino website for more info.

Where are Allbirds products made?

Our proprietary merino fabric is crafted in one of the world’s finest textile mills outside of Milan, Italy. It is an incredible factory that produces textiles of unrivaled quality, and the only wool mill in Europe certified by the European Commission for environmental sustainability.

Our shoes are then hand assembled in South Korea. We hold all of our suppliers to the highest standards for environmental and labor practices, and are proud of how factory workers are treated, and the responsible approach we take to manufacturing with minimal environmental impact.

What is your commitment to sustainability?

Our goal is to do better things in a better way. To us, this means making products that reflect and respect nature.

Our materials: All of our materials have been meticulously designed to be the most environmentally sustainable they can be. This is evident in our ZQ Certified Merino Wool and our outsole blend. We have some exciting products and novel natural materials in our design pipeline, so stay tuned!

The box: Because we sell directly to you via our website, we designed a patent pending box that is a shipping box and shoebox all in one. It uses about 40% less material, is made of 95% recycled cardboard, and is 100% recyclable – plus, we think it looks pretty cool.

Soles4Souls: When a customer returns a pair of lightly worn Allbirds that we can’t resell, we donate it to our partner organization Soles4Souls.

What’s with the name?

New Zealand is an island a bit smaller than California, and about 1,300 miles from the east coast of Australia. It’s pretty far away. In fact, we called the company Allbirds because it's so far, that when man first arrived, there were all birds, no mammals. The “Allbirds” name is our nod to a need to adopt a more sensitive approach to the way we live.

How do you think about designing shoes?

The shoe industry prioritizes profit over principles (and comfort). We let form follow function, removing unnecessary stitches, colorful branding, and unwanted shoe-tech. We strive to make beautiful shoes using considered design -- meaning, every raw material is thoughtfully chosen for its unique properties, sustainability, and its end of life.

What’s your favorite sheep joke?

Q: What do you call a sheep covered in chocolate?
A: A Candy Baa.

Does Allbirds offer coupons or discounts?

Learn more about why we don't offer coupons and discounts here.


What’s the difference between Smallbirds and Allbirds Wool Runners?

Smallbirds offers the same Wool Runner comfort, now in an even smaller footprint! They are made with the same superfine New Zealand merino wool, and are just a bit cuter. Now toddlers on a mission can get that same toe wiggling, free-as-a-bird feeling.

Laces for little kids’ shoes? You gotta be kidding me!

Don’t worry - we’ve included an elastic band under the tongue to make sure they’re easy to slip on but won’t easily slip off. Plus every pair of Smallbirds comes with a second set of sparkly laces in the box.

What about bigger kids?

Baby steps! Smallbirds are currently only available in 5T-10T in limited quantities. We wanted to see how much people like them before expanding our offering, so let us know what you think.

What about other Smallbirds styles?

Hopefully in the future! Sign up for our email list to make sure you and your little ones know what’s coming next.

Do you have Smallbirds Gift Cards?

Sure do! Even if you purchase or receive a Smallbirds Gift Card, the $90 credit can be applied toward any purchase on the Allbirds website or in-store.

What ages can wear Smallbirds?

Toddler shoe sizes don’t necessarily match their age. Not sure of their size? Check out our printable Fit Guide to find the best fit for your little one.

Are these washable?

Smallbirds are ready for adventure and a breeze to clean in the washing machine. Wash them on the wool or gentle cycle, and air dry.

How do I return these?

If you’re not satisfied with your Smallbirds for any reason, we’ll gladly take them back within 30 days. You order should have a return label within the box. You can either drop off your shoes (in the original or any box) at your local Post Office, or call 0800 COURIER (0800 2687437). You may also visit the Courier Post website to arrange collection from your home or work. Once your order is received in our warehouse you will be refunded. If you’re looking for an exchange, purchase the new pair on our website as a new order.
