The cork really does mould
Firm for the first two days, then it took the shape of my step exactly as described. My usual EU 42 was right.

A two strap sandal in sand suede with a contoured natural cork footbed and a lightweight EVA sole. The footbed shapes itself to your foot over the first weeks, which is why this silhouette has outlived every sandal trend.
Runs in EU sizes 34 to 45 with a footbed that is slightly generous; if you sit between sizes, take the smaller. Set the buckles loose for the first 2 weeks while the cork adapts, then tighten to your final fit. The suede straps soften noticeably in that same period.

Firm for the first two days, then it took the shape of my step exactly as described. My usual EU 42 was right.
Metal, not painted plastic. I adjusted them once on day one and they held through a week in Crete.
The suede is soft and the footbed actually holds the arch, which is rare at this price. Eight business days to Hamburg.
Two weeks in and there is a clear impression under the arch. Exactly what cork should do.
Walked Seville end to end the day they arrived. Nothing hurt, which I did not expect from new sandals.
Oia, boats, stone steps. They handled all of it and still look like the photos.
The footbed does not turn into a frying pan the way rubber slides do.
Wet deck, no slipping, and they dried by evening.
I sit between 38 and 39 and the 39 was right, as the guide says. Half a star off because suede and seawater are not friends.
Day one only, near the little toe. Softened after that and never came back.
Bought the black for myself. I see them on her feet most days.
Same shape, same cork, and these cost me a third of what I used to pay.
No slapping sound across a hotel lobby, which sounds petty until you have owned the alternative.
Measured 26.5cm, took the 42, no gap at the heel.
Out of the box the front strap sat too tight across the toes. Two minutes with the buckle fixed it for good.
Three days, mud included. Hosed them off and they came back.
Bought last August, worn all season, footbed has darkened where my foot sits and nothing else has changed.
Comfortable, but on gravel you feel more than with a stiffer sole. Depends what you want.
Beach every day for a week. A dry brush at the door and they were clean.
With linen trousers. Nobody said a word, which is the point.
Second season, worn hard, and the footbed is intact where my old pair split at the heel.
Tracked the whole way and packed properly.
Measured my foot at 27.2cm, took the 43, and it is exactly right.
Set them once in June and I have not touched them since.
Took a bit of force the first three times. Loosened up after that.
Purely cosmetic and honestly I like it. Worth knowing if you want them pristine.
With linen trousers on a Friday. Nobody blinked.
He is 68 and walks a lot. They are the only sandals he has not complained about.
Poolside without the skating I expected.
Fine if you accept it as suede. A brush sorts most of it.
