RAZINE is a 100-meter sprinting shoe built from, and beyond, nature. Based on the anatomy of the human foot, a special "Tendon-Drive Technology" with a strong and elastic 3D artificial tendon was used. It’s sharp and powerful, like an artery under a shiny plate. This structure can stock and explode energy to reach higher speed. The blue and orange skin helps to reduce air resistance. The warning colors differ on the medial and lateral side, creating a hallucinatory effect while running fast. The design philosophy is respecting and developing the qualities of nature. We seek “New Play” as the motivation of our innovation, and also as the DNA of Li-Ning Brand.
