AGGRESSIVE TRIPLE COMPOUND OUTSOLE
Each section of the triple compound rubber outsole is designed to perform a specific function the best it possibly can. The forefoot rubber is formulated for increased grip with deep tread specifically shaped to grab the ground while shedding mud and debris. It wraps around the toes for additional protection against rocky terrain or when doing push-ups. The midfoot is formulated from a rock climbing compound and hardened for exceptional abrasion resistance — ideal for fast roping. The heel is more dense and formulated for extreme durability with an expanded heel strike area that won't break down over time or distance.

RUGGED MIDSOLE
The midsole design wraps around the entire upper providing significantly more stability and maximum support. Support you need for your feet so they’re not smoked after being on your feet all day, whatever you’re doing. Support is foundational to Mackall™ and makes them versatile — great for combat, traveling, and for people who demand a lot of their feet.

LIGHTWEIGHT KNIT + REINFORCED TPU UPPER
100% polyester knit constructed with the strength and durability to thrive in unforgiving environments. At 230 g/sqm, it's lightweight and fast drying. 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.

PROTECTIVE TOE CAP
No stubbed toes from craggy rocks or rogue sticks on the trail. A dual layered toe cap provides extra protection and abrasion resistance across the toes. Reinforced bonding to the rubber outsole's toe bumper results in better long term durability after miles of abusive terrain.

IDEAL RUCKING OFFSET
The ideal heel-to-toe drop for rucking. 13mm offset reduces the strain on your achilles (and by proxy your ankle, knees, and hips) and helps to accommodate a natural gait in an unnatural world of asphalt and man-made surfaces.

WIDE TOE BOX
Generous forefoot area lets your toes breathe. Over time and distance during any activity including rucking or traveling, your feet will swell. This extra space reduces the friction that can occur if your feet rub against the insides of your boot.

NO SPACER MESH
Spacer mesh is soft, squishy, and feels comfortable to your hand when you touch it. But it’s a trap, literally. The first time spacer mesh looks at any kind of water, your boots get heavier and they stay that way. So we proudly do not use spacer mesh, end of story.

3D MOLDED HEEL LOCK
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.

ANATOMICALLY MOLDED TPU HEEL COUNTER
Anchors your foot with a supportive, injection molded heel counter that stabilizes your heel when you're doing dynamic, load bearing exercises.

3MM SPEED LACES
3mm as opposed to standard 5mm, just like MACV-2™. Debris and mud doesn't collect on the 3mm laces like it does on the 5mm, the 3mm rinse off and dry faster, and they're faster to tie because there's less bulk.

REFLECTIVE PULL TAB
Highly reflective pull tab on the back heel keeps you visible on the road or trail. Stay safe out there when choosing the harder path.

LACE-LOCK EYELETS
Extra top eyelets can be used to create a tight heel lock — commonly called a runner's loop or lock lace — that prevents heel slippage and excessive movement around the ankle.

DUAL DENSITY INSERT
Our custom insert uses a dual layered compression foam system that supports your entire foot from heel to toe - including contoured arch support for all 3 of your arches- throughout the duration of your foot strike.
