The front edge of the rubber molded gaiter is contoured to angle towards the leg thus catching dirt and debris before it enters the front and top boot.
The ankle area of the Prime is supported by 2 floating buckle housings which hold the unique underlying Torsion Bar strut firm against the boot reducing the injury causing rolling and twisting motion of the ankle and foot.
The unique to AXO compression molded-expandable PU Rubber ankle construction panel stretches and contracts instead of folding and wrinkling like the more common vinyl materials used by others.
All 4 of the Power Locking buckles and straps float on the exterior of the boot and reposition themselves to allow a better fit over a wider range of calf, leg and foot sizes.
The Open Cavity design of the plastics used on the Prime acts as a shock absorber actually reducing the force of an impact or blow to specific areas of the Prime boot.
The bonded 3 color sole fully wraps over the front, heel and sides of the boot guarding it from abrasion and excessive wear. The sole is replaceable by AXO and features a supportive tempered metal shank and mid-sole insert.
A 3-D molded heel cap surrounds the back of the boot guarding the heel from impacts and blows. A unique heel kick is also designed onto the heel cap allowing for a Quick Shift used for starts or a quick exit from the boot.
