Size Guide

Allbirds shoes fit true to size for most customers. If you have wide feet or are between sizes, we suggest sizing up for all styles [citation:1][citation:4]. Our shoes are unisex, so you can easily cross over between women’s and men’s sizing.

Women’s Shoes (Whole Sizes)

Most Allbirds styles come in whole sizes only. If you are a half size, select your nearest whole size—or size up if between sizes [citation:3][citation:7].

US Size	UK Size	EU Size	Foot Length (cm)
5	2 – 2.5	35	22
6	3 – 3.5	36	23
7	4 – 4.5	37	24

9	6 – 6.5	39	26
10	7 – 7.5	40	27

Men’s Shoes (Whole Sizes)

For wide feet or if you are between sizes, we recommend sizing up [citation:1][citation:4].

Fit Guidance

Whole Sizes

Most styles come in full sizes only. If you wear a half size, choose the nearest whole size. When in doubt, size up [citation:3][citation:7].

True to Size

Half Sizes

Styles like Tree Gliders and Tree Dasher 2 come in half sizes. Order your normal size unless you plan to wear thick socks [citation:3].

Select Styles

Wide Feet

Allbirds’ flexible materials adapt to a range of foot shapes. If you have wide feet, sizing up is recommended for all styles [citation:1][citation:3].

Size Up

How to Measure Your Feet

Prepare

Stand on a piece of paper with your heel against a wall. Wear the socks you plan to wear with your new shoes.

Mark & Measure

Mark the tip of your longest toe and the back of your heel. Measure the distance between the two marks in centimeters.

Compare

Match your foot length to the cm column in the chart above. If between sizes, size up for a roomier fit.

Check Product Page

Some styles (like the Courier) run small. Always check the specific product page for fit notes before ordering [citation:11].

Fit Note: Allbirds shoes fit true to size for most customers. If you have wide feet or are between sizes, we suggest sizing up for all styles [citation:1][citation:4].

Remember that Allbirds are unisex. You can easily cross over between women’s and men’s sizing—for example, a women’s 11 corresponds roughly to a men’s 8 or 9 [citation:1][citation:9].

If you are still unsure, check the customer reviews and the specific size guide on each product page, as fit can vary slightly by style [citation:3][citation:11].
