About us

S1su is a store built by skateboarders, for skateboarders. Everything we sell is something we use ourselves.

Our goal is to grow and support the skateboarding community. It’s been part of our DNA for as long as we can remember. We created this store to share a deeper insight into skate culture, embracing both the wins and the falls along the way.

S1su is rooted in a unique Finnish concept. The word “sisu” roughly translates to determination, perseverance, and resilience in the face of adversity. But it’s more than that, it’s not just momentary courage, it’s the ability to keep going when things get tough.

It’s a word that can’t truly be translated....SISU
You have to live it to understand it.
