Sympatex to introduce a study for the design of a water-proof “Shoe 4.0” at the ISPO

“Closing the loop” prototype: an upcycling production line consisting of a plastic shredder, extruder and 3D printer demonstrates how the shoe industry of the future can take advantage of recycled plastics.

What does the waterproof “Shoe 4.0” of the future look like, if it can be ecologically sustained within a closed loop system at the same time?

At its exhibit booth (hall 1 booth 300) during the 2019 ISPO, Sympatex will offer a potential answer to this essential question with a production line consisting of a plastic shredder, extruder and 3D printer to demonstrate the recycling value of plastic waste in the shoe industry, once again doing justice to its role as an undisputed pioneer in the field of sustainable functional textiles. The study illustrates how in the near future a waterproof shoe can be created from recycled materials using a modular design concept, and then broken down into the individual raw materials again with little effort. “Shoe Design 4.0” is one in a series of numerous lighthouse projects that Sympatex has recently used to show just how far the fashion and outdoor industry can already come in manufacturing and designing sustainable, waterproof apparel and shoes that are highly functional at the same time.

From waste to waterproof shoe

To illustrate the amount of valuable raw materials that are still being carelessly thrown away today, as partner of the ISPO Sport Week, Sympatex is collaborating with Munich-based sporting goods retailer Globetrotter to organize a plogging event (collecting waste while jogging) the day before the trade fair kicks-off. Sympatex has invited Erik Ahlström, Swedish creator of plogging, to join engaged consumers to collect waste during a run through the center of Munich. A portion of the collected waste will be brought to the Sympatex exhibit booth, where the PET plastic will be shredded on-site and extruded to a filament, which will then be fed into a 3D printer. In the next step, the printer will produce an outer shoe material that together with UtmosphericTM – the recently introduced seamless and waterproof Sympatex inner shoe – will represent the basic element of a waterproof shoe. The sole of this sustainable shoe is a Vibram sole, realized in Ecostep compound, a special compound made of a minimum of 30% recycled rubber. The Italian company Vibram, world leader in the production of high performance rubber soles, is heavily focused on sustainability and is very pleased to support Sympatex for this initiative. Vibram itself is engaged in a program called “the sustainable way”: it’s a concrete plan to improve sustainability performance that accurately identifies the activities and projects to undertake as company in the short, medium and long term to guarantee economic growth whilst respecting people and the planet.

ISPO visitors are cordially invited to follow the production process for this waterproof, upcycled “Shoe Design 4.0” live over the course of the four-day trade fair at the Sympatex exhibit booth.

“Each year, 23 billion* pairs of shoes manufactured from new raw materials are thrown into the trash at the end of their life cycle, or in most cases incinerated in open fires, an extreme waste of resources that also pollutes the environment, and an absolutely irresponsible approach when one considers the more sustainable alternatives that could be implemented by the industry,” explains Dr. Rüdiger Fox, Managing Director at Sympatex. “With this new lighthouse project, we want to rouse the industry and spur our market partners into a creative dialogue and collaboration. While Sympatex is not a shoe specialist, our development activities over the past few months have shown that a conscious decision is sufficient to pursue new paths toward industry-wide, sustainable shoe production based on a closed loop system. Reinventing ourselves as an industry in such a way is similar to the way Tesla is revolutionizing the automotive world. But time is running out – and together we can succeed,” adds Fox.

Results of the 38th ITMF Global Textile Industry Survey

The global textile industry appears to be turning a corner, but this is more likely a fragile and possibly temporary improvement than the start of a durable recovery. According to the 38th ITMF Global Textile Industry Survey, conducted worldwide during the second half of May 2026, business sentiment, order intake, order backlogs and capacity utilization all improved versus March — yet every indicator remains weak by historical standards, and rising costs cast doubt on how long the upturn can last.

Closing the Footwear Loop reveals challenges and opportunities for circular footwear

The footwear industry faces one of the most complex circularity challenges in the fashion sector. A new Phase 1 report from the Fashion for Good initiative Closing the Footwear Loop, developed together with Circle Economy, provides new insights into the composition, condition and recycling potential of post-consumer footwear waste.

The updated poster on biodegradable Polymers in various environments has been released

As part of the PerPlacsBio project, nova-Institute has updated its popular poster on the biodegradability of polymers in different environments. The updated version reflects current standards, certifications and the latest scientific findings. The poster can be used to assess biodegradable alternatives for use in agriculture and forestry, and it is now available in German for the first time.

A new standard to combat plastic waste in forests

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

Mario Jorge Machado re-elected President of EURATEX

The EURATEX General Assembly has re-elected Mario Jorge Machado as President of EURATEX, renewing its confidence in his leadership at a crucial moment for the European textile and clothing industry. The sector is facing rising costs, global competitive pressure and an increasingly challenging transition towards sustainability and digitalisation.

ITM 2026 makes happy participants with its international and qualified visitor profile

ITM 2026 International Textile Machinery Exhibition, one of the most prestigious meeting points of the textile machinery sector, attracted attention in its first three days, particularly with its diverse international visitor numbers. Industry professionals from all over the world had the opportunity to closely examine the latest technology machines and solutions displayed in operation. Thousands of visitors from approximately 100 countries, primarily Egypt, Pakistan, India, Uzbekistan, Syria, Turkmenistan, Tajikistan, Morocco, Algeria, and Tunisia, met at the Tüyap Fair and Congress Center for new investment and cooperation opportunities.

KARL MAYER presents a textile TEXTRONIC® innovation at ITM 2026

With highly efficient machines and continuous textile innovations, KARL MAYER underscores its role as a reliable partner for discerning top-tier customers. Just in time for ITM 2026 in Istanbul, the industry leader is introducing a true innovation: an eyelash lace with its characteristic fringed look – combined with a previously unattainable 4-way stretch. While the established fabric could until now only be produced as rigid version or with one-dimensional stretch, the new elasticity in both dimensions expands the possibilities for cross-band panel fabrics.
