Is the Revel IV High Polar warm enough for extreme cold?

Keen rates its 400g insulation to -40°F with heat-trapping layers underfoot. Owners confirm warm feet in deep winter, though activity level and socks matter.

Does it run true to size?

It generally fits close to size, but several owners say it runs large, especially with thin socks. Keen's wide Original Fit adds forefoot room, so try your usual size first.

Is it fully waterproof?

Yes. The leather upper is waterproof and the rubber outsole seals the bottom. It has no Gore-Tex membrane, so very wet, long days may eventually soak through.

How does it compare with the Revel IV Mid Polar?

The High Polar has a taller shaft for deeper snow and more ankle coverage. The Mid is lighter and easier to walk in but offers less protection.

Can I wear them for hiking?

They work for snowshoeing and winter walks, but they are heavy and stiff for technical hiking. Lighter winter hikers suit long climbs better.

What is the heel height and platform?

The heel is about 1.34 inches with a flat platform. The compression-molded EVA midsole adds cushioning underfoot.
