Is the Revel IV Mid Polar for you? The answer to that question is an easy “yes!” That said, the points below will help you form a better judgment as to whether or not the shoe is for you.

Solid option for colder climates (but not below -20°F)

If you live where the coldest temperature does not go below -20°F, this boot is a good option.

Anything below -20°F, then you are better off with the Revel IV High Polar, which provides sufficient warmth all the way down to -40°F.

Our 1st pick in

Its mid-rise collar can fend off water and snow of up to 3 to 4 inches deep. Wear a pair of gaiters if your trail has snowy parts deeper than that.

One reviewer gave a caveat when wearing the Revel IV Mid Polar hiking boot in 20 degree weather or colder. He advised to use foot warmers.

Watertight up to 4 inches deep

Some testers commented on the loose heel of the KEEN Revel IV Mid Polar. Its rear confines could be less roomy, based on a small number of reports.

Another wearer added that she wished the shoe would get tighter around the ankle so that snow wouldn’t go down against the heel. But a good gaiter would take care of that.

Wonky arch 

A reviewer was unhappy to find the arch wonky. An owner finds the boot’s midfoot section not particularly supportive.
