I found a great review of traditional and modern winter footwear from an old Finnish Partio magazine printed in 1964. Each pair of footwear was tested for waterproofness, amount of insulation and the other qualities (fit, price etc.) were evaluated by the authors. The footwear they tested wear plastic, rubber and leather boots, rubber-tipped leather boots, leather-tipped wool felt boots, three different sets of traditional Finnish "moccasins" and a pair of rubber sneakers. Apart from their durability, the "moccasins" fared the best. They were followed by the felt boots, rubber-tipped leather boots and rubber boots and lastly by plastic boots.
