What is EVA?
We have a long list of eco friendly shoe brands here at PlanetShoes.com that use EVA as the material for the footbed of their shoe. EVA is a dense foam which acts as an excellent and durable shock absorber in the sole of many shoes. Originally popularized in athletic shoe soles, EVA is now being used industry wide and in a wide variety of shoe shapes and styles.
EVA actually stands for Ethylene Vinyl Acetate and is a polymer widely used in a number of applications – from biomedical engineering to photovoltaic modules (solar panels). In the case of footwear, these companies are using the expanded rubber of foam version forms of the polymer. The reason EVA is considered more eco-friendly is that it doesn’t use chlorine in its production. This means there is less toxicity released during degradation in a land fill somewhere if you discard your shoes.
Recycled EVA footbed material is considered even more eco-friendly because not only is the material itself environmentally safer, but it is likewise not being simply discarded and is instead being re-used again and again. EVA is also widely used in Vegan shoes because it is man made and animal friendly.
In many cases, companies are also using EVA almost as a binding agent for other eco-friendly shoe materials. Jute, bamboo, cork and other materials are incorporated with the EVA to create better function, a great look, and an eco friendly shoe.
