Pound the pavement or go off-road. 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.
Seamless, one-piece 100D polyester mesh provides breathability and flexibility without cramping your toes. At 330 g/sqm it's the ideal balance of weight and toughness.
High-wear areas are reinforced with a protective TPU film. We targeted the toe area for abrasion resistance and the midfoot to heel area for additional lockdown support.
A 10mm heel-to-toe drop allows for the ideal balance between a running stride and a rucking gait. You have enough of a lift to reduce the strain on your achilles and support your heel strike while still controlling your cadence.
Comfortable PU foam bolsters lock in the heel to prevent slippage and excessive movement around the ankle. This allows you to secure your heel into the shoe without relying on lace-locking or lacing too tightly.
Anchors your foot with a supportive, injection molded heel counter that stabilizes your heel when you're moving with momentum.
Dense, PU foam insert custom made to fit the contours of the foot supporting all three (3) arches of the foot — yes, you have three arches in your foot (the medial longitudinal arch, the lateral longitudinal arch and the anterior transverse arch).

Gradient Density™ means the midsole has more bounce under the ball of your foot and gradually becomes more stable towards your heel. It's uniquely formulated to provide cushioning and rebound with better long-term durability than any other running shoe on the market. No marshmallows here.
