Our take on the KEEN Mens Circadia Mid Polar Boot

The KEEN Circadia Mid Polar is a men's insulated winter hiking boot built for cold, wet trails. It pairs a KEEN.DRY waterproof membrane with 200g KEEN.WARM insulation rated to -25°F/-32°C, plus a TPR outsole with multi-directional lugs and a heel-capture system for stability. The roomy original KEEN fit and cushioned Luftcore midsole suit hikers and backpackers who want warmth without a stiff mountaineering boot. Against lighter winter hikers it runs warmer and more protective; against full mountaineering boots it is more flexible and comfortable on the move.

About the KEEN Mens Circadia Mid Polar Boot

The KEEN Circadia Mid Polar is a men's insulated, waterproof hiking boot built for cold-weather trails. It has 200g KEEN.WARM insulation rated to -25°F/-32°C. A KEEN.DRY waterproof, breathable membrane keeps feet dry, and a quick-dry lining with odor control helps keep the inside fresh.

The outsole is a higher-traction TPR design with multi-directional lugs. A heel-capture system adds stability, and a notched ankle provides support. The cushioned midsole uses Luftcore technology for comfort on backpacking and mountaineering trips.

The upper is made of premium leather and performance mesh. It has a PFC-free water repellent finish, and the leather comes from an LWG-certified tannery. The boot has the original KEEN fit with a roomy toe box.

Questions and answers

How cold can the Circadia Mid Polar handle?
KEEN rates the 200g KEEN.WARM insulation to -25°F/-32°C. That figure assumes you are active; standing still in deep cold will feel colder.
Is it fully waterproof?
Yes. It uses a KEEN.DRY waterproof, breathable membrane, and the upper is treated with a PFC-free water repellent.
How does the fit run?
It uses KEEN's original fit with a roomy toe box. If you are between sizes or wear thick socks, that extra room helps.
Can I use it for mountaineering?
It is a mid-height hiking boot, not a crampon-compatible mountaineering boot. It suits winter trails, snowshoeing and backpacking, not steep ice.
What is the heel-capture system for?
It locks the heel in place to reduce slipping inside the boot and improve stability on uneven ground.
Does it need special care?
The leather and mesh upper benefits from regular cleaning and re-waterproofing to keep the water repellent working.
Where is the KEEN Mens Circadia Mid Polar Boot cheapest?
At Out&Back Outdoor, for $91.00, as of our latest check.
