Columbia Portlander Omni-Heat Infinity Boots - Black

Trekking boots feature an advanced, multi-layer Omni-Tech membrane for waterproofing and adequate air circulation.

The elevated upper covering the ankle is composed of durable textile and nubuck. Sealed seams provide additional protection from wind and moisture. To increase thermal comfort, a lining with Omni-Heat Infinity technology with a 200 g/m2 grammage is used. The operation of this innovative technology is based on gold dots applied to the lining, which reflect the heat generated by the human body and help retain it inside the boots. The applied design with golden dots provides 40% more insulation compared to the classic Omni-Heat system. 

The front of the boots has been further reinforced with a layer of TPU plastic to protect against mechanical damage. To ensure very good traction, a high-quality Adapt Trax outsole was used, which allows stable movement on any terrain. The shoe features an anatomically contoured Techlite midsole, which absorbs shocks and uneven terrain. A specially molded area in the midfoot area provides additional stability and increases comfort during prolonged wear. 

A wide loop at the back of the upper makes it easy to remove and put on the shoes.
