Spotted: Having inherited their family shoe business, and after learning the ins and outs of the industry, a pair of Croatian brothers, the Boljars, decided to step away from the literal toxicity of footwear. They created Miret, an eco-friendly sneaker made from 97 per cent natural materials. The upper is wool, the insole is hemp, and the outer is natural rubber and cork.
The remaining three per cent of the shoe consists of synthetic glue and polyester thread. The brand emphasises that although its footwear is low impact, it is by no means ‘sustainable’. Production still affects the Earth, and most of the company’s products, including the sneakers, are not easily compostable. Making shoes from bio-based materials is a huge improvement, though, and something the company wants to continually improve.
Replacing the glue and thread with natural materials is a priority, as is continuing to raise the profile of the threat of plastic pollution to the natural environment. Assembling the shoes in the same country that the brand is based in helps reduce emissions. And the Life Cycle Assessment of the full emissions footprint of a single pair of Miret sneakers is 3.7 kilogrammes of carbon dioxide. That compares to the 14 kilogrammes of carbon dioxide typically created during the production of a pair of sneakers.
Environmentally friendly sneakers are becoming more common and are an exciting area of development. Springwise has spotted materials innovations that include plant-based oils and eucalyptus used in a biodegradable shoe and a brand that offers a vegan, fully traceable sneaker.
