How to Find the Perfect Fit

Birkenstock Size Guide

All shoes on this website are listed in either US/AU or EU sizing.

To ensure you find the perfect fit, we recommend checking two important guides that you will find alongside all our shoes - the SIZE GUIDE and the FIT GUIDE.

SIZE GUIDE

The black SIZE GUIDE button is located directly under the size listing that accompanies each shoe. This guide contains size conversion charts so you can easily compare US/AU, UK or EU sizing, info on how to measure your foot to find your true size, what to expect the first time you wear your shoes, and any other info that may help you in your selection. The below size conversion charts are considered universal, though some differences do occur between brands, so we recommend also checking out each shoe's SIZE GUIDE.

FIT GUIDE - FIND THE PERFECT FIT

The 'FIND THE PERFECT FIT' (desktop version) or 'FIT GUIDE' (mobile version) is located directly below the pictures of the shoe (on desktop) or via the black FIT GUIDE button (mobile version). This guide shares information on how the shoe fits and the level of support offered. Our team takes great pride in making sure that every shoe delivers styles, comfort and the perfect fit. Every style is tried on, discussed and scored to ensure that you are receiving real information that is in line with what a customer would experience in store, so you can make the most informed decision.

Runs Small - Runs Large: Unfortunately not all brands are made equal in the size department. Just like with clothes, different countries, designers or manufacturers may produce shoes that 'run small' (ie the shoes are smaller than what we would usually expect for that size) or 'run large' (ie the shoes are larger than what we would usually expect for that size). We have made it easier to identify if this is the case by giving each shoe a star positioned between 1 (runs small) and 5 (runs large). If a star is displayed in position 1 under 'runs small' we recommend going up a size to what you would usually purchase. If the star is in position 5 under 'runs large', we recommend going down a size to what you would usually purchase. If the star is right in the middle in position 3, it is considered 'true to size' (ie the shoes are the size we would expect) and you should go with your normal size. Birkenstocks are true to size.

Runs Narrow - Runs Large: Different shoes accommodate different width feet. Some styles are made with wide feet in mind, and others may provide a better fit for narrow feet. The position of the star on the 'Runs Narrow' - 'Runs Wide' chart will help you select the best shoe for your feet. If a star is displayed in position 1 under 'Runs Narrow', it is perfect for very narrow feet, though not suited for regular or wide feet. If the star is in position 5 under 'Runs Wide', it is ideal for those seeking extra width than the average shoe. If the star is right in the middle in position 3, it is considered a regular width. You will notice that this part of the FIT GUIDE is left blank for Birkenstock shoes. This is because Birkenstocks come in both Regular (R) and Narrow (N) fittings, so you can select the width when you select the size. Narrow Birkenstocks are designed for people with very narrow feet (approx 5% of the population), so go with Regular (R) if you are unsure - you can always make adjustments using the straps and buckles. 

Low Support - High Support: We pride ourselves in delivering shoes that make your feet smile. That means providing style, comfort and the perfect fit. Comfort often comes down to the level of support you want, and need, in a shoe. If a star is displayed in position 1 under 'Low Support', it has minimal support features built into the shoe (your standard rubber thong or flipflop is a good example) - there is no additional arch support, footbed contouring, or cushioning integrated into the shoe. If the star is in position 5 under 'High Support', the shoe includes the full spectrum of support features (like a Birkenstock, or many Frankie4, Dr Kong or FitFlop styles). Some of these features may include cross arch support, inner and outer longitudinal arch support, heel cups, cushioned footbeds, a toe bar to promote the natural rolling movement of the foot, comfortable straps and hardware, soft leathers and materials, and a flexible footbed.
