This year the Insano walks right into the house of high-end, responsive boots and, to show them who’s boss, dips his BOAs® in their soup. Bloop! BLOOP! Water, fire, air, and dirt. F**king BOAs®. How they work? Pure science and engineering. Although we can all agree that we don’t want to talk to no scientists because they lyin’ and get us pissed, we should agree that they come up with some great boot closure systems. On the Insano specifically, we use a BOA® Focus System with The Closer™ lace guide, which is designed to give you a precise fit in the upper and lower zone of the boot while The Closer™ lace guide disperses lace tension across the entire boot to give you a comfortable fit, free from pressure points. Hot lava, snow, rain and fog, long neck giraffes and pet cats and dogs are all things that the Insano could, though probably should not, walk over thanks to the traction provided by the lug pattern on our Michelin® Peak Sole. The Insano is the stiffest boot in our line and is built for those ride-or-die ninjas looking for unmatched response. Whoop Whoop!
