Built for flying and ground crews operating in dry cold conditions below 15°F, the boot pairs a rugged canvas upper with a thick, insulated rubber sole — designed to be worn over a separate wool or felt liner for maximum warmth. Nicknamed the \"Mukluk\" for its resemblance to traditional Arctic footwear, it became a staple of cold-weather military kit for decades, valued for being lighter and more flexible than the all-rubber \"bunny boot\" alternative while still holding up in genuinely brutal winter conditions.\u003c\/p\u003e","brand":"Pottstown Army Navy","offers":[{"title":"N-1B Mukluk Boots Medium (Size 9-10)","offer_id":50527136841805,"sku":null,"price":29.99,"currency_code":"USD","in_stock":true},{"title":"Small 100% Wool Thermal Liner","offer_id":50527136874573,"sku":null,"price":19.95,"currency_code":"USD","in_stock":true},{"title":"Medium 100% Wool Thermal Liner","offer_id":50527136907341,"sku":null,"price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/1362\/7981\/files\/muklukBootside2.png?v=1790357903","url":"https:\/\/pottstownarmynavy.com\/products\/usgi-mukluk-boot-n-1b-extreme-cold-weather-boots","provider":"Pottstown Army Navy","version":"1.0","type":"link"}
