Hermès Izmir Men’s Sandals: Sizing, Break-In, and One Year of Wear

I bought a pair of Hermès Izmir sandals at a Hermès boutique in Japan in July 2025. I have now worn them through a full summer, and this is what I would tell someone standing in the shop trying to decide.

Two things matter most: sizing, and knowing what these sandals are actually for. The second one is where most disappointment comes from.

Sizing: I took a 40, and it was true to size

My usual shoe size is 24.5–25 cm (roughly EU 39–40, around US men’s 6.5–7). I took the size 40 and did not size up. It fitted correctly.

You will find advice online saying to go half a size or a full size up. That advice is not wrong, but it is incomplete. The Izmir has a single wide strap cut into the shape of an H covering the instep, which means fit is decided by the height of your instep more than by the length of your foot.

• Standard instep — take your normal size. Mine fitted with no adjustment.
• High instep — the strap will press across the top of the foot. Going up one size gives the strap more room, and this is where the size-up advice comes from.
• Do not over-size. A sandal that is too long will slap as you walk, and there is no lacing to hold it on.

If you can try them on, try your normal size first and work from there.

What the leather actually looks like

These are the black calfskin version, photographed the day I brought them home.

The defining feature is that strap: the H is not printed or stamped on, it is the shape of the leather itself. That is why the sandal reads as quiet rather than loud. There is no visible logo to notice — either you recognise the shape or you do not.

From above you can see what nobody sees once they are on your feet. The insole is a restrained grey, stamped HERMÈS PARIS in the centre.

And the underside of the H strap is a warm gold tone. Worn, it is invisible. Left by the door, it shows. Everything facing outward is deliberately plain; the colour is kept on the inside. I like that arrangement a great deal.

Turn them over and the sole carries the stamp: HERMÈS / 40 / veau (calfskin) / MADE IN ITALY. In this photograph the sole is still completely unmarked — this is the first day.

Three things a year of wear taught me

1. The leather really does break in

Out of the box the strap was stiff, and I briefly wondered whether I had made an expensive mistake. That changed. Over the summer the H strap learned the shape of my instep, and the spot that used to press no longer does. A year on, they feel moulded to my feet. Do not judge these on the first wear.

2. The thin sole is a real limitation

I want to be honest here. The Izmir is flat, and the sole is thin. That thinness is exactly where the elegance comes from — and it means there is almost no cushioning.

Walk a city all day in these, cover a few kilometres of sightseeing, and your feet will tell you about it. They are not a substitute for a sneaker. If you are buying them expecting a do-everything summer shoe, this is where you will be let down.

3. Hotels and resorts are where they belong

So where do they work? After a year the answer is clear: short distances, in places where you are seen.

• Walking from your hotel room down to the lounge or the restaurant
• Poolside and terraces
• Resort settings where you want to dress properly but keep the feet light
• Short local outings — dinner a few streets away

Flip-flops are too casual for that gap and leather shoes are too heavy. The Izmir sits exactly in the middle. They are also thin and light to pack, which makes a strong case for keeping a pair in the suitcase.

Who should buy them, and who should not

• Buy if you travel often and spend real time in hotels and resorts — and want your feet light without looking sloppy.
• Buy if you dislike conspicuous logos. The Izmir only speaks through its shape.
• Do not buy if you are looking for an all-day walking sandal. The thin sole makes this a certain regret.
• Do not buy as a daily shoe for wet conditions. It is leather, and it wants a little care.

Specifications and notes

• Purchased: July 2025, Hermès boutique in Japan, tried on in store.
• Model: Izmir, men’s. Calfskin (veau), Made in Italy.
• Colour: black, with a grey insole and gold-toned lining beneath the strap.
• Size taken: 40, with a usual size of 24.5–25 cm. True to size for a standard instep.
• Fit tip: instep height decides the fit, not foot length. Try before buying where possible.
• Worn: roughly one summer season. Leather breaks in well; sole remains thin by design.
• Best use: hotels, resorts, short outings.

They are expensive. But framed correctly — not as an everyday sandal, but as the shoe that makes the few minutes between your room and the restaurant look right — I cannot think of anything better.

Frequently asked questions

Do Hermès Izmir sandals run small? Should I size up?

Not necessarily. My usual shoe size is 24.5–25 cm and I took a 40, which fitted correctly with no adjustment. The Izmir has a single wide strap cut into the shape of an H across the instep, so fit is decided by the height of your instep more than by the length of your foot. A standard instep takes your normal size; a high instep is where the size-up advice comes from. Do not over-size — a sandal that is too long slaps as you walk, and there is no lacing to hold it on.

Does the Hermès Izmir leather break in?

Yes. Out of the box the strap was stiff enough that I briefly wondered whether I had made an expensive mistake. Over a summer the H strap learned the shape of my instep, and the spot that used to press no longer does. Do not judge these on the first wear.

Are Hermès Izmir sandals comfortable for walking all day?

No, and this is the honest limitation. The Izmir is flat and the sole is thin — that thinness is where the elegance comes from, and it means there is almost no cushioning. Cover a few kilometres of sightseeing and your feet will tell you about it. They are not a substitute for a sneaker.

Where do Hermès Izmir sandals actually work?

Short distances, in places where you are seen: walking from your hotel room down to the lounge or the restaurant, poolside and terraces, resort settings where you want to dress properly but keep the feet light, and short local outings such as dinner a few streets away. They are also thin and light to pack, which makes a good case for keeping a pair in the suitcase.

What markings are on them?

The insole is a restrained grey, stamped HERMÈS PARIS in the centre. The sole carries HERMÈS / 40 / veau (calfskin) / MADE IN ITALY. The underside of the H strap is a warm gold tone — invisible when worn, visible when they are left by the door. Everything facing outward is deliberately plain, with the colour kept on the inside.
