Functional safety winter boots consist of several safety-related components. Unlike women's or men's boots or winter shoes for leisure like from Rieker, Tamaris or shoes from Ugg, the construction here is a bit more complicated. This includes, for example, a puncture-resistant midsole made of a textile such as Kevlar®, this insulates better against cold from below than a steel midsole. Also advantageous is the use of plastic toe caps, even if it is not physically proven that these transmit less cold than steel caps. Decisive for good insulation is the inner lining. For example, the German manufacturer of safety shoes, Elten, offers either a woven lamb lining made of a synthetic fiber or a lining made of genuine lambskin. The only thing more functional is a functional lining with a Gore-Tex® climate membrane. Great advantage also: the shoe and its upper material is not only breathable but also waterproof. And that's a big advantage in winter, especially when you spend a long time outside. A sneaker made of leather or fabric is then completely out of place here.
A good outsole is worth its weight in gold, especially for boots in adverse conditions
As with car tires, safety shoes also have a winter tread or a winter compound of the outsole. Thus, the rubber content of the shoe sole of the winter shoes or winter boots is much higher, as this material remains flexible even at low temperatures and brings the winter tread neatly on the ground. The tread depth of the lace-up boots is also much deeper to be able to really eat into the snow and ice. The winter shoe is usually very limited to a certain period and can not be worn all year round, unlike normal shoes or boots.
