Luka 1 'Next Nature'

Designed for No. 77 and made for every athlete craving speed and efficiency, Luka's debut delivers the goods. The first shoe with full-length Formula 23 foam, it has an ultra-supportive fit crafted with the step-back in mind. Meanwhile, strong and lightweight Flight Wire cables keep you feeling contained.

Shout Out Slovenia

These shoes pull colour inspiration from the natural beauty of Slovenia—Luka's home country—and its lush forests, snow-capped mountains and miles of scenic coastline.

Cable Container

Embroidered Flight Wire—think of the braided cables that support bridges—wraps around the shoe's upper to keep your feet secure and contained.

Geared for Quickness

Full-length Formula 23 foam translates to responsive support for your entire foot, helping you find new ways to create space. Under the foam, a stabilising plate helps you feel quick when Euro-stepping through the lane.

Step Back With Confidence

A rubber wrap built for ankle support complements an efficient traction system designed to optimise Luka's step-back—and yours, too.
