All models in the Hanwag Active Winter Collection combine high functionality with a design suitable for everyday use. These high-quality and highly durable winter boots and shoes guarantee to keep your feet warm and dry in the cold and wet months. With Hanwag footwear, this goes without saying. Additionally though, the Hanwag research and development team has been investigating ways to make footwear more sustainable.
Hanwag has been making high-quality and durable mountain boots since it was founded in 1921. It uses two complex shoemaking techniques only – cemented construction and double stitching. This means that all Hanwag boots and shoes are fully resoleable, which prolongs their lifespan, saves resources and helps protect the environment. Hanwag sources all its raw materials very carefully for the highest quality and durability and predominantly local and eco-friendly processing. In order to ensure the shortest possible transport routes, the Bavarian bootmakers manufacture exclusively at their own production sites in Europe.
With Eco-Shell Footwear, Hanwag is now presenting a new, proprietary membrane that is perfect for functional winter footwear. Eco-Shell Footwear is waterproof, breathable and sustainable. Thanks to its innovative technology, Hanwag uses absolutely no fluorochemicals in its new Eco-Shell Active Winter models. In addition, the PULJA LADY ES, SAISA HIGH LADY ES, SAISA MID LADY ES, ANROS ES and ANVOK ES have a warm lining made of 100% recycled polyester and uppers made from high-quality leather from European tanneries. They are all made exclusively in Europe. They are particularly long-lasting, resoleable and can ultimately by disposed of in domestic waste as Eco-Shell footwear is combustible and harmless for health and the environment.
Andreas Settele, Head of Research and Development at Hanwag explains the idea behind Eco-Shell Footwear:
“As a sustainable brand, it’s important for us to produce shoes that function, but also reflect our DNA. We are committed to developing sustainable products, including eco-friendly supply chain, production and materials. This is why we decided to make all the new models in the Active Winter 2018/19 product line completely free from fluorinated chemicals. PFCs are harmful to people, animals and the environment They break down very slowly (they are characterized as persistent) and short chain PFCs have been found in water and air samples at some of the most remote areas in our planet.” With our Eco-Shell Footwear, we are taking the first step towards being able make our future production and supply chain free from problematic chemicals.”
How does the Eco-Shell footwear membrane work?
The Eco-Shell footwear membrane works as a hydrophilic system. The hydrophilic system is a chemical process (A) where sweat, i.e. moisture (B) on the inside of the membrane is transformed into water vapour (C) and transported away to evaporate outside. Eco-Shell Footwear has a polyurethane (PU) membrane and is therefore free from polytetrafluoroethylene (PFTE). The new Eco-Shell footwear models in the Active Winter Collection have a three-layer laminate: The outer layer is made from polyamide to protect the membrane. In the middle layer a PU membrane effectively stops moisture from getting in from the outside, while transporting moisture away from the foot. Finally, a warm lining made from 100% recycled polyester protects feet from the cold.
