The Jasari is a new spike from Nike which is designed for fast racing on synthetic tracks. Named for the Swahili word which translates to “brave” or “courageous,” the shoe makes sure that nothing holds you back from an optimum performance. The upper is a lightweight mesh with a minimum of materials which fits close, with a smooth interior and breathable surface. A layer of EVA cushions the foot with good flexibility and a low heel to protect for the longest races from 800-10,000 meters including the Steeplechase. Permanent pins are designed for grip, without the fear of losing a spike.
