Designed for #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 embroidery keeps you feeling contained, whether you're playing indoors or out. This is the assist you've been waiting for—get out there and make your shot. This version is designed wide and made for play on outdoor courts. Cable Container Embroidered Flight Wire—think of the braided cables that support bridges—wrap around the shoe's upper to keep your feet secure and contained. Full-Length Foam Full-length Formula 23 foam translates to responsive support for your entire foot, helping you find new ways to create space. Stability at the Core You can see the stabilizing plate right in the middle of the midsole. It zig-zags under the foam to create a strong core that lets you wrench back and pop off a perfect jumper.
