Inspired by nature, the new product developed by PIEP (Polymer Engineering Innovation Hub), a technology and innovation centre located in Guimarães, in collaboration with Atlanta Steps and CTCP, promises to be a small revolution in footwear. Portugal is once again standing out as an innovator in the footwear sector with the world premiere of a new generation of biomimetic soles at the Lineapelle Fair. This is the largest international event for footwear accessories and took place from the 23rd to the 25th of September in Milan, Italy.
This new type of sole was developed by PIEP in collaboration with the BioShoes4All project. Inspired by natural forms, particularly the human heart, spiders’ webs and octopus’ suckers, these innovative soles combine design, functionality, and sustainability, paving the way for the future of casual footwear.
"Learning from nature to solve human challenges is nothing new for PIEP researchers. It was the starting point for yet another innovation that combines science, technology, and sustainability for the benefit of users and the environment”, emphasises Bruno Pereira da Silva, PIEP’s Director of Public Affairs and Sustainability.
Biomimetic soles are 22% lighter for enhanced everyday comfort and lightness, while providing 60% greater energy absorption. They distribute plantar pressure more effectively and protect against impact. They are also made from more sustainable materials, incorporating bio-TPU (thermoplastic polyurethane produced from renewable biological sources). This contributes to a reduction of up to 8% in CO₂ emissions and 6% in the use of fossil resources.
"Our collection of biomimetic soles is generating enthusiasm thanks to its validated results and engaging storytelling, which attract customers and add value to the product”, said João Carvalho from Atlanta Steps’ commercial department at the fair.
The solution, which is in the process of being patented internationally under the title ‘Sole structure for an article of footwear’, has been validated in certified tests and complies with the ISO/TR 20880:2007 international standard regarding safety and grip.
Developed by PIEP in collaboration with Atlanta Steps and CTCP, this innovative solution is part of the BioShoes4All project, which is considered the largest in the history of the Portuguese footwear industry. It involves an investment of over 72 million euros, financed by PRR – Next Generation EU. The project will reinforce the international competitiveness of the Portuguese cluster and establish the country as a world leader in sustainable innovation within the sector.
Founded in Guimarães in 2000, PIEP is a renowned Portuguese technology and innovation centre that specialises in polymer engineering and innovative solutions for the plastics industry and related sectors, including automotive, packaging, aeronautics, space, railways, energy, footwear, construction, and medical devices. Thanks to continued investment in state-of-the-art equipment, PIEP has become an expert in eco-design, product development, advanced manufacturing processes, testing and trials, smart and sustainable polymers, the circular economy, the environment, digitalisation and automation. PIEP collaborates with universities, research centres and industry to promote sustainability and technological advances in the sector, applying laboratory innovation to the challenges facing our society.
