Thermo Kiruna Mid WP is another really useful winter hiker by Merrell. A waterproof leather upper and shell keep you dry, while the interior is lined with 200 grams of Primaloft Gold ECO insulation underneath a fleece lining. The outsole is a thick flexible lug, providing excellent traction in the snow. All of this while remaining reasonable lightweight as well.
Available at Glebe Trotters.
