Xtep shows off mass-balanced shoe 'breakthrough'

Sports brand Xtep, owned by eponymous Hong Kong-based parent company Xtep, the group behind K-Swiss and Palladium, has joined hands with polymer manufacturer Covestro and footwear business Silan to develop low-impact athletic shoes.



The latter two firms have already been partners for around 20 years.

Xtep’s announcement of their three-way collaboration coincided with the launch of its 360-Eco running shoe, described as the brand’s first model made with low-carbon, mass-balanced raw materials such as Covestro’s partly biomass-based Desmopan CQ thermoplastic polyurethane (TPU), Desmodur CQ and toluene diisocyanate (TDI) and Desmodur CQ diphenylmethane-4,4’-diisocyanate (MDI). As of last month, the addition of CQ, meaning "circular intelligence", to Covestro product names denotes their minimum 25% "alternative" (ie, non-fossil) raw material content.

Compared with conventional petroleum-derived polyurethane, a pair of size 41 360-Eco trainers can bring carbon emissions down by as much as 81%, according to Xtep, making them mesh well with the national government's own “dual carbon” goals involving peak emissions by 2030 and carbon neutrality by 2060.

“The successful development of Xtep’s low-carbon running shoe demonstrates the excellent performance of mass-balanced Desmopan CQ TPU products when it comes to multifilament mesh fabrics, shoe uppers, midsoles and supporting pieces,” commented head of sales and market development for Covestro’s TPU division in Greater China, Edwin Wu.

The sportswear brand itself called the model a “breakthrough” on par with its launch of a 100% polylactic acid (PLA) windbreaker back in June, and in line with its strategy to make “world-class Chinese running shoes” more sustainably, first announced earlier this autumn. It said that it plans to only increase use of PLA and other “low-carbon environmentally friendly materials” over the next couple of years.
