The legendary Arctic professional boots now have the familiar TractionPro grip sole from safety shoes. Primaloft® lining material keeps frosty feet warm even when the material is compressed. Primaloft® keeps feet 38% warmer in dry conditions and twice as warm in wet conditions compared to competing materials Primaloft® is made from 90% recycled plastic bottle fibers. With the help of laces on the edge of the boots, the feet are protected even in particularly high snow.
