Flyknit upper promotes natural movement of the foot for total comfort and fit as well as optimal performance. Bottom part of the upper is fused with a durable skin layer for stabilization and support. 5/8" collar hugs your foot to give you that sock-like fit and added stability you need. Lunarlon midsole gives you lightweight, responsive cushioning that lasts from your first drill to your last. Rubber outsole is versatile for multi-surface performance. Forefoot lugs extend from outsole during quick cuts for a new level of traction.
