Handmade in Portugal.
Cut from premium nappa, full grain and suede, then built on the last by makers who do little else. It takes years to master a shoe. We're still finding ways to make it better.
One box. Nothing wasted.
Every pair ships in a crisp white box built to be the shipping box too — no second carton, nothing thrown away. Inside, a reusable ETQ travel bag for wherever they go next. A detail you notice after you buy, not just before.
Endless comfort.
A structured silhouette on the outside. Inside, a memory-foam insole with airflow channels that move moisture with every step. The kind of shoe you forget you're wearing — and keep on long after you meant to.

How to measure
Let’s find your perfect fit. Place a sheet of paper on the floor against the wall and put your feet (with socks) on it, heels against the wall. Make sure you lean on your feet with full power when measuring. Now you simply draw a line at the end of the biggest foot. Measure the distance with a ruler and find the size that matches it: see size table. Are you in between sizes? In that case, we suggest taking the bigger size.

How to measure
Place a sheet of paper on the floor against a wall. Stand on it with your socks on, heels touching the wall.
Draw a line at the end of your longest toe and measure the distance from the wall using a ruler.
Between sizes?
Choose the larger size. Feet naturally expand throughout the day, so measuring in the evening usually gives the most accurate result.
