When a rut-enraged moose decides to eject you from his territory, these remarkably fleet-footed boots can mean the difference between making a safe escape or getting trampled into the tundra. But don’t think gaining agility means giving up warmth. LaCrosse® Aero Insulator Boots are rated for polar-grade cold – from freezing all the way down to -60ºF – with a tough AeroForm™ shell that stays flexible in frigid temperatures. Better yet, your foot and calf are surrounded by an insulating fleece-lined neoprene core that provides comfortable cushioning and waterproof performance – ideal for when a Chinook wind turns the snowscape into a flood zone. Underfoot, the industrial tread channels out snow and slush, so you can outrun a mad bull, or – just as effective – your buddy who’s wearing heavy pac boots.
