  • Desperate for a high-traction boot, particularly one that provides extra-surefootedness on frozen terrain.

Revel IV High Polar: A showcase of KEEN technologies

If there is ever a brand that takes homegrown tech seriously, it would have to be KEEN. The Revel IV High Polar is a testament to this with the following:

KEEN.WARM. At 400 g, this insulation ensures warmth up to the lower calf in below-zero conditions. This tech, coupled with the boot’s heat-trapping insole, translates to cozy hikes for many hours!

KEEN.DRY. The Revel IV High Polar is fully waterproof because of this. Since the boot in question has a high clearance, a gaiter is not required for keeping your tootsies dry in, say, 5 inches of snow.

KEEN.Polar Traction. This exclusive outsole provides high surface traction on icy surfaces. Frigid conditions are not a problem as this rubber component does not freeze easily, keeping its effectiveness intact in extreme cold.
