| 39 | 6–6.5 | 5.5 |

How to Measure Your Feet
Stand barefoot on a sheet of paper placed against a wall. Mark the back of your heel and the tip of your longest toe, then measure the distance between the two marks.
Measure both feet because one foot is often slightly larger than the other. Use the larger measurement when selecting your size. Birkenstock also recommends checking whether you need a Regular/Wide or Narrow footbed based on your foot width.
How Should Birkenstock Shoes Fit?
Birkenstock shoes should allow your feet to rest naturally inside the contoured footbed. Leave about 5 mm of space in front of your toes and 5 mm behind your heel. This allows your feet to move naturally while walking without touching the edges of the footbed.
Your toes should never press against the front edge, and your heel should sit comfortably inside the heel cup. If your foot extends beyond the edges of the footbed, you may need a larger size or a wider footbed.
Buying Tips
- Measure both feet before ordering.
- Compare your measurements with Birkenstock’s official size chart.
- Choose between Regular/Wide and Narrow footbeds.
- Remember that Birkenstock uses EU sizing.
- Adjust the straps for a secure but comfortable fit.
- Read customer reviews for style-specific sizing.
- Buy from authorized retailers with easy returns.
Common Birkenstock Sizing Mistakes
One common mistake is choosing your regular sneaker size without checking the EU conversion. Birkenstock sizing is based on European measurements, so using the official size chart helps improve accuracy.
Another mistake is ignoring footbed width. Many people focus only on shoe length, but selecting the correct Regular/Wide or Narrow footbed often makes a significant difference in comfort and support.
Conclusion
A properly fitted pair of Birkenstock shoes provides outstanding comfort, support, and durability for everyday wear. Measuring your feet and comparing them with the official Birkenstock size chart is the easiest way to find the right size.
Because Birkenstock uses EU sizing and offers different footbed widths, always check the official size guide before purchasing. Choosing the correct length and width will help you enjoy the full comfort of your Birkenstock footwear.
