Wyandotte, Michigan – A new running shoe from Brooks has been created using a polyurethane-based cushioning system from BASF.
The Brooks Levitate running shoe is the first to feature the DNA AMP midsole, made from a new blend of BASF’s Elastopan SportsLight material.
Changes were made both to the formulation and the chemical nature of the polyurethane to provide runners with 72% energy return for every unit of force. The result of their seven-year collaboration, the companies say, is a midsole with enhanced comfort and durability, and which reduces energy expenditure during running.
Another advantage, they say, is that the compression set effectiveness is better than the materials normally used to produce midsoles, such as ethylene–vinyl acetate. This extends the shoe’s useful life by enabling the midsole to retain its original thickness.
‘We are seeing two key trends within the athletic shoe market: consumer demand for lightweight, comfortable and durable shoes and increased focus on automating the footwear production process,’ said Chau Nguyen, BASF’s footwear market manager in North America. ‘The result is renewed interest in and use of high performance polyurethane for athletic shoes.’
Brooks Running’s senior innovation developer Zach Boteilho added, ‘We are excited to partner with BASF to bring to life the revolutionary new DNA AMP midsole technology that releases energy straight back to the runner, making the experience so fun they can run forever.’
