Sizing Hermès Sandals: Why It Matters More Than You Think

Choosing the proper size in a set of Hermès sandals is more important than in many other types of footwear. Because Hermès uses full-weight, firm calfskin, a sandal that is even half a size too small will will not expand in the way that a thinner or cheaper hide would. Conversely, a sandal that is oversized will slide, fold and crease unattractively, and deteriorate asymmetrically. The leather softening process that makes Hermès sandals progressively more comfortable assumes a correct starting size — the leather conforms to your specific foot within its appropriate size.

This article covers every sizing consideration for Hermès sandals: how Hermès sizing works relative to other systems, the how the Oran and Izmir each fit, the correct foot measurement method, and what to do when you are between sizes. It also handles special cases — wide feet, narrow heels, different fits for different leather types.

The Hermès Size Chart

Hermès sandals use European (Paris) sizing, which includes both whole and half sizes. This is a foot-length-based system using Paris point units — a Paris point measures roughly 6.67 millimeters. The size options in the Hermès sandal range generally extends from EU 34 through EU 42. EU sizes convert to other systems as follows: EU 37 = US Women’s 7 = UK 4; EU 38 = US Women’s 7.5–8 = UK 5; EU 39 = US Women’s 8.5–9 = UK 6; EU 40 = US Women’s 9–9.5 = UK 6.5. These conversions are approximate and work best for standard foot widths.

One key distinction of Hermès sizing is that it varies slightly between styles. The Oran hermes men sandals and Izmir are built on different foot-shaped frames, and the equivalent EU number may feel different in each. A significant number of wearers find that their size in the Izmir versus the Oran differs by one half-size, even in the same EU number. This is not a manufacturing inconsistency — it is a reflection of the different last shapes.

Oran-Specific Sizing: The Oran Sizing Guide

The Hermès Oran typically matches standard EU sizing for average foot widths. For a purchase made without in-person fitting, the most reliable strategy is to use your actual European size based on foot length measurement. If your foot is on the boundary between sizes, choosing the larger half-size usually works better, because the leather cannot stretch into a larger length but will adapt to a slightly roomy fit during the wear-in period.

For feet wider than average — especially for feet noticeably broader than standard — the sizing approach changes. The H-cutout vamp has a fixed width at any given size, and a significantly wide foot may be limited by it. Going half a size larger can provide additional room across the vamp. The trade-off is that the sandal may be slightly long, which can cause the back strap to feel insufficiently taut even when set at maximum tension. Some wide-footed buyers address this by having a cobbler make minor modifications to the strap.

Getting the Right Izmir Size: How to Size the Izmir

The Izmir’s sealed heel produces a distinct sizing need than the Oran. Because the back is fixed rather than adjustable, the contact at the heel and rear of the foot is wholly a function of the size picked. For typical heel breadth, the Izmir fits true to size — the leather fits closely around the back without tightening or slipping off. For slim heel bones, going down one half-size can offer a better hold. For substantial heel bones, choosing the next half-size up gives the enclosed back additional room.

The break-in process for the Izmir involves the enclosed back conforming to the heel’s specific contours, which requires 5 to 10 wears in Epsom. If the enclosed back feels acutely uncomfortable rather than simply firm, it is important to reconsider the size — real pain, rather than the normal stiffness of new hide, may indicate that the size is incorrect.

Measuring Your Foot: Step-by-Step Guide

The best method to determine your Hermès size if you cannot visit a store is to measure your foot precisely and compare against Hermès’s published size chart. To measure correctly: stand on a piece of paper with your full weight on the foot, align the paper to the wall and press your heel against it, and mark the end of your longest toe with a pencil or pen. Measure the distance from the wall to the mark in millimeters — this measurement is your foot length. Compare your measured foot length to the Hermès size chart. According to sizing experts at The RealReal, foot measurement is the single most reliable predictor of fit success for online purchases.
