London, UK – Footwear company VivoBarefoot is planning to introduce a plant-based shoe range in 2019. The Primus Bio range will use a corn-based TPU in both the sole and upper.
The company says that 60% of the outsole and 30% of the upper is made from bio-TPU based on DuPont Tate & Lyle’s plant-derived Susterra propanediol. It believes this will make it the world’s least petroleum-reliant performance shoe.
Susterra is made via the fermentation of glucose made from cornstarch. VivoBarefoot claims the material gives shoes greater flexibility in the cold, and is resilient to abrasion and general wear.
‘Sustainability is our journey. We believe that the perfect shoe has minimal interference with natural movement and minimal impact on the environment,’ said design director Asher Clark. ‘The Primus Bio champions the future of sustainable materials which I believe will be largely bio-based.
‘This is an exciting step in the right direction away from the single use petroleum-based alternatives commonly used in athletic footwear. Every action counts in our journey of redefining the world’s relationship with environmentally-damaging materials.’
