Here's what other sites are saying:

Make the backcountry's glittering trails a little more accessible with the help of Karhu's Frontier Boot - a comfortable boot with an NNN BC outsole, supportive, yet low-cut thermoplastic cuff for your wide track runs. Your feet won't be left sore thanks to soft 3D-molded midsoles and 200-gram Thinsulate insulation for toe-warming comfort.

- Mountain Gear refers to the men's version

We designed the new Frontier from the bottom up, using 3D Molded Midsoles and our men s and women s lasts for superior comfort. The new lacing system and 3D-Stitched Tongue hold the foot firmly in place, and 200g Thinsulate insulation and a zip-up lace cover will keep your feet warm and dry all day long. The slimmer lighter profile of the Frontier provides a smooth flex up front, while the NNN BC outsole has double steering grooves for controlling your skis on groomed or backcountry terrain.Specs: Lacing Fingers.
