First running shoe midsole based on new biopolymer grade by BASF
The footwear specialist for ultrarunning and long-distance shoes, Mount to Coast, Hong Kong, China, and BASF, Ludwigshafen, Germany have entered into a strategic partnership to explore high-performance, sustainable solutions for runners. CircleCELL™, an innovative midsole, is the first footwear technology the collaboration has produced. Based on BASF’s new biopolymer ecoflex® BMB, the new midsole is 90% more durable while showing the same energy return as midsoles made of polyether block amide (PEBA), a material widely used for performance running shoes. Biomass-balanced ecoflex® supports Mount to Coast in increasing the use of renewable feedstocks in its unique process of foaming the CircleCELL™ midsole while preserving the characteristics performance shoes require, most importantly, durability.
