Our customer service agents are available Monday to Friday, from 9 am to 5 pm EST, to address all your queries.

Sizing varies among our styles, but all of our shoes are medium width and most are full sizes only. Please note that we now do include half sizes in our Tree Breezers!

The Wool collection starts out a little snug and then stretches naturally, while the Tree material is super accommodating, but will fit similarly over time as it retains shape.

We've found most full-size customers stick with their full size in both materials.

If you're a half size, we've found most customers size up in every silhouette beside the Tree Runners. If you have a wider foot and you're a half size, we'd suggest sizing up to the next full size in everything!

Still not sure? We'd love to talk to you about it! Reach out to one of our fit specialists at for some personalized advice!

Our padded insole is made from a castor bean oil blend with a wool lining topper. This cushioned insert has very noticeable arch support compared to minimalist shoes :)

If you are seeking a simply designed casual shoe with arch support, we hope you'll give these a shot!

For customers looking to use their own inserts or orthotics, our insole is easily removable to make these adjustments. In addition, the wool upper will stretch and may accommodate an orthotic on top of our wool insole. However, some customers have noticed that they do not need to use their orthotics given the level of cushion, so it's worth a try!

Allbirds socks are true to size for most customers, so your normal sock size should be a happy fit here too. Our socks run from small to extra large, and there’s this handy (footy?) chart below to help you find the best fit :) 

Women’s US Sizes: S (5-7), M (8-10), L (11)

Men’s US Sizes: M (7-8), L (9-12), XL (13-14)

Allbirds were designed to be easily cleaned :)

We find that hand washing will help preserve the longevity of your Allbirds. If that doesn't do the trick, throw them in the washing machine on the wool or gentle cycle. But first, be sure to remove the insoles and laces. For the best results, use your favorite gentle detergent and a delicates bag.

Don’t forget to air dry your Allbirds just like in the good ol' days—and whatever you do, avoid the dryer and bleach at all costs!

Our goal is to reverse the environmental impact of consumption by informing people to make better, more conscious decisions for themselves as well as the planet. To us, this means making products that reflect and respect nature, while educating our fans in the process.

Our Materials:Our materials are meticulously chosen to be some of the most environmentally sustainable. We rely on gold standard certifications like ZQ for Wool through NZ Merino and Forest Stewardship Council (FSC) for Tree. We are even working to create the world's first fully Marine Stewardship Council-certified supply chain for apparel products with the launch of our TrinoXO™ material. We have more exciting products and novel natural materials in our design pipeline, so stay tuned!

Our Packaging:Our commitment to planet-friendly materials also extends to our packaging. Because we sell directly to you via our website, we designed a shoebox, a shopping bag, and a mailer all in one. Additionally, our footwear packaging is FSC Recycled Certified to be 100% recycled content, our apparel packaging is all FSC Certified, and all packaging is recyclable.

Our Carbon Footprint:We are proud to be a 100% carbon neutral company, but understand there is still work to do. We have a plan to eliminate our products’ carbon footprint, and it’s already in action. First, we measure the emissions of every product, from its raw materials to its end of life. This measurement is reflected in the numbers you can find on everything we make, noting the carbon footprint emitted to produce it. Next, we reduce our impact by incorporating things like natural and recycled materials. And finally, we offset what is left with certified carbon credits, making Allbirds a Climate Neutral-certified business. But our goal is even bigger—to emit no carbon in the first place. We can create a sustainable future, but only if we hold each other accountable. Want to take a deeper dive? Learn more.

End of Life: When a customer returns a pair of lightly worn Allbirds that are unable to be sold, we donate them to our partner organization Soles4Souls who distributes to those in need. We recognize circularity is an area where we can improve, and we’re hard at work thinking of solutions here.

We're proud of the responsible approach we take to manufacturing with minimal environmental impact. By offering a carefully curated product range, we’re able to maintain a small, tight-knit supply chain. We have only a handful of finished good factories, many of whom we’ve worked with for years. In addition, we accept third-party, mutually recognized standards, like WRAP and SMETA, to reduce audit fatigue at factories and ensure safe, lawful, human and ethical manufacturing practices.


  • South Korea - Our shoes are hand-assembled in Busan, South Korea, which at one time had the nickname of “Shoe City.”
  • China - Our partners work out of a China-based factory in Shenzhen, where knitting and hand-assembly takes place. This factory is WRAP certified, and they pride themselves on being one of the nation's most innovative producers.


  • North Carolina - We partnered with a manufacturing team in North Carolina who have been making world-class socks for over 100 years!
  • Peru - Our team here offers environmental education and training programs for workers, covering topics like how to practice sustainability at work and at home.
  • Indonesia - We partake in the ILO Better Work Initiative, which aligns factory practices to local laws and the UN International Labor Organization's standards. The annual program includes advisory and consulting services and management training.
  • Vietnam - Our factory here is LEED Certified, built for energy efficiency with rainwater capture and reuse, and green space for native plants.
  • China - Our partner in China who knits our sweaters makes sure nothing goes to waste, recycling all excess yarn to be used again.

We're proud of the responsible approach we take to manufacturing with minimal environmental impact. By offering a carefully curated product range, we’re able to maintain a relatively small, tight-knit supply chain. We have only a handful of finished good factories, many of whom we’ve worked with for years. In addition, we accept third-party, mutually recognized standards, like WRAP and SMETA, to reduce audit fatigue at factories and ensure safe, lawful, human and ethical manufacturing practices.

Allbirds’s success depends on our supply network partnerships and the people who make our products. In support of this, the Allbirds Responsible Sourcing Program was developed to help identify the best partners and to protect and promote healthy and sustainable working conditions. To achieve this goal, Allbirds only sources from a select number of strategic suppliers that are willing to certify via our contracts and Supplier Code of Conduct (“Code”). These certifications ensure workers are treated with dignity, fairness, and an elevated regard for their health and safety. We also expect full transparency of their own supply chains – providing us the names and locations of their sub-suppliers.

Beyond written commitments and prior to placing orders, Allbirds also expects supplier factories to undertake an onsite social assessment by a professional, independent, third-party social assessment firm. Social assessments ensure suppliers meet our minimum expectations with regards to working conditions as specified in our Code. Assessments, which may or may not be announced, include confidential worker interviews, review of documentation and records, and visual inspection of safety conditions. Assessment focus is also influenced and informed by identified material, and regionally specific challenges to ensure the appropriate due diligence is undertaken.

Finally, Allbirds requires suppliers to follow-up and improve upon any identified deficiencies in a realistic and timely manner, emphasizing the need for root-cause-analysis and management systems to ensure long term performance and accountability. Allbirds expects our suppliers to be open and honest with us about their successes and challenges.
