How to Measure your feet for the perfect Allbirds fitting?

How do i know my Allbirds size?

How to understand shoe width with more parameters can be found here.Find out How to measure your shoe size correctly here.

10 easy steps to measure your feet correctly:

  1. Measure your feet in the afternoon.
    Your feet swell during the day, it’s best to measure your feet at their fullest
  2. Stand When Measuring
    When in a wheelchair there’s no pressure on the feet, so it’s unnecessary to stand up.
  3. Wear socks
    With Allbirds, you most probably won’t wear socks. If you plan to wear sock, make sure you wear them when you measure your feet.
  4. Be precise
  5. Measure both feet
    Measure your left and right foot separately as they’re not the same length. Take the biggest measurement to determine your shoe Size
  6. Stand on your piece of paper
    Keeping your body weight over your foot, trace a thin line around the outside of your entire foot.
  7. Start drawing
    When drawing the line, hold the pen perpendicular to the ground.
  8. Measure the length of your feet
    Measure vertically down the length of your foot tracing. This is your foot length.
  9. Find your width fitting by drawing or with measuring tape
    Measure horizontally across the widest part of your foot tracing. This is your foot width.
  10. Determine your Allbirds size in the conversion charts
    Start from the measurement in inches or centimeters and define your size in the charts for men, women or kids

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

How do Allbirds sneakers and shoes fit? 

The superfine merino fabric is comfortably snug and expertly conforms to fit the contours of your foot, while our 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.

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. In general, the sneaker styles are also good for people with wide feet because the upper fabric is flexible.

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 don’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 wool/delicates cycle (cold water). The insoles can be washed using an 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’s no regulations or safety requirements in place.

Do Allbirds shoes have arch support?

Not really. They do offer premium replacement insoles — high cushion, lined with our merino fabric — or you can use other insoles or inserts that are available on the market and offer arch support . These insoles are designed for plush comfort and 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, because of the wool material, the shoes will be wet, 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.

Do Allbirds come in Children’s sizes?

Unfortunately, not yet. However, the smallest ladies’ size is EU 35, US 5, UK 2-2.5 , so a teenager of 10-11 years old will be able to fit the shoes that might save the planet and their future.

The picture in the post is one of the partnerships between Allbirds and Shake Shack: read all about it here.
Collaborating with a burger joint might seem random at first, but Allbirds and Shake Shack share a lot of values. Like Allbirds, they’re committed to making better things in a better way—it starts with their ingredients and spans into building up local communities while empowering small businesses and creatives.
