The 5K Boost Lerna represents decades of Adidas’ innovation and design concepts brought under one silhouette. The upper features alternating patches of breathable mesh, varying colors of brushed suede and a crisp white rubber heel clip for stability. This eclectic blend of colors and materials is only added to by the BOOST midsole which begins as a solid crepe sole before giving way to a translucent rubber that gives you a window into the technological wonder that cushions your foot. Finally, the shoe is finished with a red-black rubber outsole.
