How cold can the Revel IV High Polar handle?

KEEN rates it to -40°F with its warmest insulation. Most owners report comfortable feet well below freezing, though activity level and socks matter.

Is it fully waterproof?

Yes. The waterproof leather and textile upper with a sealed membrane keeps feet dry in slush and wet snow. Snow entering over the top is the main limit.

It runs roomy, with a wide toe box for thick socks. Some buyers size down half a size; try it with the socks you plan to wear.

Is it good for hiking?

It works for winter hikes and snowshoeing, but it is heavy and stiff for long distances. Shorter, lighter boots suit casual walking better.

When is the price lowest?

Winter boots like this usually drop after the season, in late winter and spring. The current best new price is $160 at eBay as of November 8, 2026.

One pair of boots. Insoles are included; socks and care products are not.
