Keen Circadia Polar Walking Boots

An iconic hiker, simplified and winterised. Get-out-and-go warmth for cold-weather hiking, featuring 200g of KEEN.WARM insulation.

Waterproof Leather Upper

Encasing feet in a cosy layer of breathable, waterproof protection, the Circadia Polar utilise a combination of leather and performance mesh upper. The boots use environmentally preferred premium leather (LWG-certified tannery) which has a breathable KEEN.DRY membrane, that supplies your feet with protection against water and moisture, keeping your feet dry. The boots have performance mesh addition to further provide your feet with a layer of fresh, constant airflow, working to prevent you from overheating and ruining your hike. A quick-dry lining will also make sure to keep your feet dry during intense activities. A notch in the back of the boots provides you with additional comfort, helping to prevent irritation and discomfort from occurring. Alongside this, the boots have Eco Anti-Odour to provide you with natural odour control and ensure your feet smell and feel fresh while the KEEN.PROTECT toe bumper helps protect feet from rocks and uneven surfaces. The boots also feature KEEN.WARM, the brand's signature insulation that is extremely compressible and light for the warmth it provides. This insulation will retain heat in colder wintry environments, which means that you will be able to take on all weather conditions without the risk of feeling exposed. Featuring iconic Keen comfort, the original fit of the boot secures your heel while offering generous space across your forefoot so your toes can spread out naturally. Completing the upper is a speed-lace webbing system, with a top collar hook, providing you with a comfortable snug fit, and ensuring your feet remain locked in.

KEEN LuftCore Midsole

Supplying feet with a layer of lightweight cushioning, the Circadia utilises LuftCore technology through the midsole. The LuftCore embeds a lightweight foam core inside the midsole, which works to absorb shock and provide additional cushioning for your feet. The midsole also utilises a Thermal Heat Shield insole to capture further warmth. Additionally, the boots have a heel-capture system, providing stability and support, keeping your foot stable on the rocky unpredictable terrain.

KEEN.FUSION Rubber Outsole

The Circadia has a non-marking KEEN.FUSION rubber outsole, to provide you high levels of traction and grip on varied terrains. This works alongside 5mm multi-directional lugs to further enhance your traction, allowing you to go on long trails with constantly changing terrain and still have exceptional stability.
