If you have wide feet or are in between sizes for whole-size shoes, You should size up for all models. If you have wide feet or prefer a roomier fit in your running shoes, go up a half size.

Like our beloved planet needs more sustainable and eco-friendly sneakers, the planet also needs a full Allbirds sizing and fitting review. 😉 Allbirds sneakers are great for an active lifestyle in the city or outdoors.

Allbird’s advises sizing up for people who require half sizes. I wear size 10E shoes, therefore I chose size 11 because I needed more room for the width, and the received Allbirds shoes suited me quite well. In my case this concludes than Allbirds shoes run nearly a full size larger than listed and are obviously not true to size. As a result, I could suggest going up to the next size from your own shoe size (if that is possible).

How to clean your Allbirds Sneakers

Allbirds are shoes built to travel, so they’re likely to get dirty.

If your Allbirds tennis shoes or sneakers start to feel less than fresh, you can easily clean them in the washing machine on the wool or gentle cycle.
Important notice: Remove the insoles and laces. Use your favorite gentle detergent and a delicates bag for the best results.
To preserve the fluorine-free water-repellent treatment on the wool upper, it is recommended to hand wash the shoes of the Mizzle collection. Spot cleaning dirt with warm water and gentle soap is the best but if they need a deep clean, machine washing is still okay.
Don’t Tumble dry your shoes, air-dry your Allbirds sneakers. Avoid the dryer and bleach at all costs!

Allbirds Size Guide FAQ and Fitting

Do I need to size up for Allbirds flats?

With Allbirds Tree Breezers, it’s preferable to size up by a half size, like with other flats. They fit rather snugly, so if you have wide feet, you might want to size them bigger up to a full size.

Do Allbirds shoes fit true to size?

Yes, Allbirds fit true to size for most customers. If you have wide feet or are between sizes, we suggest you size up for all styles except the Tree Runner. The sneaker styles are generally good for people with wide feet because the upper fabric is flexible.

Do Allbirds come in Children’s sizes?

Yes, Allbirds offers kid’s shoes under the brand Smallbirds. Some sneakers come in sizes US 5T, EU size 22. However, the smallest ladies’ size is EU 35, US 5, UK 2-2.5, so a teenager of 10-11 years old can fit the shoes that might save the planet and their future.

How do Allbirds sneakers and shoes fit? 

Allbirds fit well and comfortably, Even though Allbirds only offers full sizes. The superfine merino fabric is comfortably snug and expertly conforms to fit the contours of your foot, while the mesh tree fabric is form-fitting and stretchy, hugging your feet in all the right places. Due to this adaptability, Allbirds only offers whole sizes.

Are Allbirds Shoes and Sneakers easy to clean?

Allbirds are built to travel, so they’re likely to get dirty. It depends on the style, but generally, Allbirds doesn’t require a lot of care. On the whole, they’re super durable and low maintenance.
Remove the insoles and laces, and put the shoes in the washing machine on the wool/delicates cycle (cold water). The insoles can be washed using a linen bag or by hand for the best result. Use a gentle detergent and avoid bleach at all costs.
Do NOT tumble dry – air dry your Allbirds. Reinsert the insole and laces and get on with your day.

Do Allbirds shoes have Occupational shoes, work shoes, Safety Shoes, and Boots?

No, not yet. However many Allbirds can be used in professional environments when there are no regulations or safety requirements in place.

Do Allbirds shoes have arch support?

Not really. They offer premium replacement insoles — high cushion, lined with our merino fabric — or you can use other insoles or inserts available on the market and offer arch support. These insoles are designed for plush comfort and are made with vegetable oil.

Can Allbirds shoes get wet?

How do Allbirds perform on a rainy day? They work well in the rain. The main material is wool, which has some natural properties that avoid light rain getting in. However, if you step in a puddle, your feet will be soaked. Again, the shoes will be wet because of the wool material, but your feet won’t get cold if you do.

Are Allbirds shoes good for walking long distances?

Yes, Allbirds are great walking shoes. The shoes are originally designed to travel around the world. Whether you’re traveling, running errands, or wearing them for everyday use, Allbirds feel comfortable even after walking for miles.
