Over the years, PAJAR has developed and implemented techniques to improve their high quality boots. With the addition of a patented insulating mid-sole (Iso-Lana) made up of small air bubbles between layers of aluminum, felt, and wool, Pajar boots can withstand severe cold up to -74 degrees Celsius. All seams are tape-sealed and the adhesive construction further ensures the waterproof quality of the boots. PAJAR boots are produced in a wide range of styles, materials, and colours to keep up with fashion trends. They are advertised in consumer fashion magazines and have become a necessity for trendsetters.these are slightly used with a couple scuffs on the toe box but nothing serious. plenty of life left.
