The Gradient Density™ EVA cushioning has substantial bounce/rebound under the ball of the foot (for running, jumping, explosiveness), and gradually becomes more stable towards the heel for adaptation to lifting / squatting. GORUCK believes this midsole offers long term durability to rival any other running shoe on the market.

Seamless, one-piece 100D polyester mesh provides breathability and flexibility without cramping the toes. At 330 g/sqm, it's the ideal balance of weight and toughness. High-wear areas are reinforced with a protective TPU film. GORUCK targeted the toe area for abrasion resistance and the midfoot to heel area for additional lockdown support.

Two different rubber compounds form a single, seamless rubber outsole that performs in even the most demanding terrain. The forefoot rubber is formulated for increased grip and the heel is dense, durable, and won't wear down after miles of running or ruck running.

Comfortable PU foam bolsters lock in the heel to prevent slippage and excessive movement around the ankle, while a molded TPU heel counter anchors the foot and stabilizes the heel during dynamic, load bearing exercises. A 10mm heel-to-toe drop also creates the ideal balance between a running stride and a rucking gait.
