Designed for athletes who run and lift, the Hybrid RN takes you from sprints to squats without missing a beat. A forefoot Air Zoom unit pairs with ReactX foam to give you the responsive cushioning your runs need. The wide outsole features both sticky and high-abrasion rubber for stability and grip during dynamic movements. Design: Responsive Cushioning: ReactX foam and a forefoot Air Zoom unit deliver responsive energy return without feeling overly squishy during heavy lifts or sled work. Stable Base: A wide outsole gives you optimal stability and solid ground contact. Rubber at the heel helps limit how the midsole foam expands during heavy lifts. Sticky Outsole: Traction makes all the difference during grip-critical moves. The outsole pairs sticky rubber with high-abrasion rubber for durable, multi-surface traction. Midfoot Containment: Going from burpee broad jumps to sprints isn't easy. An X-shaped overlay on the upper works with the laces to help secure your foot as you switch moves. Additional Details
