I purchased these deadstock items about 20 years ago from a vintage clothing store in Osaka and wore them only a few times. I'm now selling them to organize my collection. These are 1986 N-1B overboots. BOOT EXTREME COLD WEATHER HEAVY TYPE N-1B MUKLUK TALON zip Thick insoles are layered two on each side. Shoe Length: Long Material: Canvas, Rubber Size: US small 26-28cm These are made large because they have two very thick inserts. These are the cold weather boots used by the US Air Force, commonly known as Mukluks. The design is unique and interesting, but you can bend the shaft and wear them like sneakers, making them more practical than they look. From a military perspective, they were designed to be used with flight jackets like the N-2 and 3B, and completed with N-4B gloves. The large TALON zipper is cool. Those with smaller feet can wear them over their shoes, while those with larger feet can wear them directly. Adjust with insoles or thick socks. For reference, I was able to put my foot in them while wearing a 26.5cm Converse All Star sneaker (outer sole length 30cm x width 10cm), so they should fit even those with quite large feet if worn barefoot. Vintage items in good condition are currently very rare, and in my experience, you rarely see them in vintage clothing stores. They are a collectible item, so please consider them. (The shaft does not stand up on its own in the photos because of the stuffing.) #N-1B #Military #US Military Issue #Mukluk #Overboots
