Supportive foam and a secure design optimize power transfer. Low to the ground with a secure fit, the Nike Zoom Javelin Elite 3 is ready to "send it," thanks to a design that's built for stability and power transfer. Lock In - Reduced height compared to the previous iteration helps keep you closer to the ground, while a second hook-and-loop strap helps keep your foot from sliding. High-Density Foam - High-density foam adds cushioning while you throw. A full-length plate helps create ground contact with minimal flex at foot plant. More Benefits - Midsole has a slight negative heel-to-toe drop that puts the heel lower than the forefoot, giving you an optimal launch angle at foot plant. Toe box is lined with foam for comfort. Product Details - World Athletics approved. Steel spike receptacles.
