Built for cold. Made for adrenaline. The Pure Adrenaline Serac Series Snowmobile Boot is purpose-built for winter riders, with 1000g of thermal insulation, a waterproof sock construction and a dual dial lacing system that help keep your feet warm, dry and locked in when conditions get rough. The manufacturer cold-rates the boot to -40°F / -40°C.

Fit: two dials tighten the cable lacing for a custom, locked-in fit, with easy on and off and adjustable tightness, so you can snug the boot down before you ride and loosen it when you are off the sled.

Warmth and comfort: 1000g thermal insulation padding and a long-pile fleece lining add soft comfort and warmth for long days on the trail, in the mountains or in the backcountry.

Protection and traction: a cold-resistant PU upper with rubber sheet reinforcement, a reinforced toe and heel, and a protective ankle structure add protection and ankle support. A rugged rubber and EVA outsole provides grip, cushioning and durability.
