Finding the right fit in a Birkenstock is the single most important step to unlocking their comfort. A perfect Birkenstock fit is about length and how your foot sits within the contoured footbed. This guide will provide you with charts and steps to ensure your next pair feels like it was custom-made for you. Read on to find the right sizes for women, men and kids.

 

How Should Birkenstock Fit?

 

The perfect Birkenstock fit should feel supportive and spacious. Your heel should sit in the deep heel cup, and your toes should have enough room to spread out naturally without touching the front lip. Birkenstocks tend to run slightly large, so we recommend sizing down, especially if they are between sizes. The fit for sandals and clogs is based on the same footbed, but some find the clogs to feel more snug due to their closed-toe design.

Birkenstock Width Charts

 

Birkenstock’s unique approach to comfort includes two width options. You can identify the width of a pair by looking at the footprint symbol on the footbed: a filled-in footprint means Narrow, while an outlined footprint means Regular.

Adults

For Birkenstocks, the width is just as important as the length.

Regular Fit: Designed for medium to wide feet. This is the original, classic Birkenstock fit and the best choice for most people, providing ample room for the feet to spread out naturally.

                                          

Narrow Fit: Designed for distinctly slender feet. If you consistently find other shoe brands to be too wide, this may be the right option for you.

 

Recommendation: Unless you have a noticeably narrow foot, always start with the Regular fit. A little extra room is better than a cramped fit.

                                   

                                   

Adult Width	Recommended For
Regular	Medium to Wide Feet
Narrow	Slender, Narrow Feet
Kids’ Width	Recommended For
Regular	Medium to Wide Feet
Narrow	Slender, Narrow Feet

                                   

 

How to Find Your Perfect Birkenstock Fit

 

Follow these steps to ensure your Birkenstocks fit perfectly:

 

1. Measure Your Foot: Place a piece of paper on the floor and stand on it. Trace the outline of your foot and measure the distance from the back of your heel to the tip of your longest toe. Use this measurement in centimeters (CM) to find your size on the chart.
2. Check for Wiggle Room: When standing in the shoe, aim for about ¼ inch (5mm) of space in front of your toes and behind your heel. Your toes should not touch the front rim of the footbed as you walk.
3. Align with the Contours: Ensure the contours of the footbed match your foot. The toe grip bar should rest comfortably beneath your toe joints, and your arch should feel supported by the footbed’s curves.
4. Confirm the Width: Your foot should sit comfortably within the footbed, not on top of its raised edges. The sides of your foot should not be pressed tightly against the rim.
5. Adjust the Straps: Tighten the straps so the sandal feels secure, but not restrictive. You should be able to fit one finger comfortably between the strap and your foot.

 

 

FAQs

 

Are Birkenstocks true to size?

 

Birkenstocks run slightly large and are roomy. Many people find their perfect fit by sizing down from their usual shoe size. For the most accurate choice, measure your foot in centimeters and consult the official size chart. Side note, your toes should not touch the front rim of the footbed. 

 

Are Birkenstocks clogs true to size?

 

Yes, Birkenstock clogs like Boston and Arizona are built on the same footbed as the sandals and follow the same sizing. However, as it's a closed-toe style, some people prefer the security of their true size, while others still opt to size down for a snug fit.

 

What size of Birkenstock should I get?

 

The best way is to measure your foot length and match it to the CM column in the official size chart. If you are between sizes, the general recommendation is to size down. The goal is a snug fit where your foot rests perfectly within the footbed's contours.

 

What size is 38 and 39 in Birkenstocks?

 

A Birkenstock size EU 38 typically corresponds to a UK 5 or a US Women's 7-7.5. An EU 39 corresponds to a UK 5.5-6 or a US Women's 8-8.5. Always refer to the official chart for the most precise conversion.

 

What is the standard width for Birkenstocks?

 

The "Regular" width is the standard and most common fit for Birkenstocks. It's designed for feet of a medium to wide width and is the recommended starting point for nearly all wearers unless they know they have exceptionally narrow feet.

You've got the full playbook now. Finding your perfect Birkenstock fit is a simple process of matching your foot to the right length, width, and footbed contours. With this, you're investing in your own personalized support.
