Über uns

It all started with a suitcase. One summer, my sister was packing for a trip with her friends, but there was simply no space left for all her shoes. She wanted to bring a pair for every outfit, every occasion, every moment. My father, Yves, looked at the overflowing suitcase and joked: “What if we made a shoe that could be all of them at once?" That joke became an idea, and that idea became a mission.

From that day on, our living room turned into a small design lab. Sketches, prototypes, sleepless nights, and countless trials later, SEYES was born... a shoe system built around one simple truth: you don’t need more, you just need better.

Together with my father, I, León, joined from the very beginning, shaping every detail, from the modular design to the website, from the colors to the story we tell.

SEYES is the world’s first fully modular shoe: made of three interchangeable parts, the sole, the insole, and the upper, that can be swapped in seconds. It lets you travel lighter, create endless looks, and reduce waste, without ever compromising on style or comfort. Every component is crafted in Spain, but designed in Switzerland with sustainable, vegan materials, designed to last and to be replaced individually. Because we believe in slow fashion, in circular design, and in creating products that help the planet breathe a little easier.

What began as a small family idea has grown into a vision for the future of footwear. A vision where less is more, and one sole can become many.

The very first finished pair... proof that dreams, ideas, and countless hours can take shape. This is where Seyes truly began.
