Named after the Greek goddess of stars, Astra guides the way for every explorer.

Born from real trail running experiences, every detail tells a story—what we see, feel, and use on the trails becomes wearable memory. Each pattern carries the rhythm of running, turning movement into expression.

We blend 16.5-micron New Zealand merino wool with nylon, enhanced by physical fiber-structuring technology. Use natural temperature regulation, odor resistance, and the breathable comfort of wool, combined with the elasticity and durability of nylon. Lightweight yet tough, it's engineered for the outdoors, designed for everyday.

Astra Collection bridges wilderness and city with innovative merino wool. On your unique path, may you always shine.
