The Meindl Narvik GTX is a three-season boot made from durable nubuck leather with a Gore-Tex® Insulated Comfort membrane for 100% waterproofing and breathability in cold climates. Rubberised front for extra protection. The insole is made from winter felt for extra warmth. Great shoe for gliding snowshoes. The Meindl Multigrip ROCK outsole has PU shock absorption and an environmentally friendly "Green Diamond" technology, i.e. a softer rubber with metal particles for slightly better grip on slippery surfaces. The sole has also been equipped with Frame Technology - a kind of frame construction that makes the sole more torsionally rigid and laterally stable and keeps the foot in place in all positions.
