Men's hiking boots KEEN Circadia Mid Polar black/steel grey (1026762)

KEEN Circadia Mid Polar black/steel grey men's hiking boots are advanced footwear designed for demanding terrain conditions, offering a range of technologies that ensure comfort and protection. The insulation used in this model provides warmth even in the coldest conditions, making them an ideal choice for winter hikes. Thanks to KEEN.WARM technology, feet are protected from low temperatures, which is crucial during prolonged outdoor exposure.

Waterproofing and breathability

The KEEN Circadia Mid Polar boots are equipped with KEEN.DRY technology, which provides waterproofing while allowing moisture to escape. This combination guarantees a dry and comfortable climate for the feet, even during intense use in rainy conditions. The breathability of the materials further supports thermal comfort, enabling long-term wear without overheating.

Protection and durability

The full rand reinforcing the KEEN Circadia Mid Polar boots provides additional protection against impacts and mechanical damage. The solid construction and durable materials used in production ensure the longevity of the footwear, even with intensive use. The KEEN.FUSION outsole offers excellent grip and stability on various surfaces, which is essential during demanding hikes.

Eco-friendly solutions and comfort

The KEEN Circadia Mid Polar model is environmentally friendly thanks to the use of PFC-Free technology, which means the elimination of harmful chemicals in the manufacturing process. Additionally, the boots are equipped with the ECO ODOR CONTROL system, which minimizes unpleasant odors, ensuring freshness throughout the day. The Thermal Heat Shield insole supports thermal insulation, helping to maintain an optimal temperature inside the boot.

Comfort of use and fit

The high collar and Speed-lacing system allow precise adjustment of the boots to the foot, increasing wearing comfort and stability on the trail. Weighing only 600 g, the boots are relatively lightweight, making them easier to wear during long hikes. KEEN Circadia Mid Polar is an excellent choice for mountain expedition enthusiasts who value quality, comfort, and protection in demanding conditions.

Water Repellent
Modern water repellent system. Thanks to the water-repellent coating, liquid does not absorb into the fabric.
KEEN.WARM
An innovative insulation made mainly from bamboo shoots, created by the KEEN brand. It is lightweight and anti-microbial, helping to keep the heat generated by the body close to the foot while blocking cold air from passing through the shoe upper.
ECO ODOR CONTROL
A technology that relies on natural probiotics to provide a coating that blocks the growth of microbes responsible for creating unpleasant odours.
KEEN.DRY
A highly comfortable waterproof membrane used in KEEN shoes. It is highly breathable and wicks moisture away from the outside of the shoe, keeping the foot dry whatever the weather.
LuftCore
LuftCore technology is an air-injected core in higher-density PU foam designed to absorb shock for heel comfort.
KEEN.FUSION
A state-of-the-art solution that connects the upper of the shoe to the sole in an innovative way, guaranteeing a permanent connection without the use of adhesives or soluble substances.

    How to measure insole length - instructions in 3 steps

    1. Remove the insole from a shoe that fits well on your foot and place it on a flat, hard surface.

    2. Mark the tip of the insole (the furthest point near the toe) and the back of the heel.

    3. Measure the distance between the marked points with a ruler or tape measure - this is the length of the insole, which should be compared with the size chart.

    How to measure the length of your foot - instructions in 4 steps

    1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

    2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

    3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

    4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
