BASF - We create chemistry
Long-lasting shock absorption
Experienced joggers know that new running shoes wear out quickly. After just a few runs, their cushioning capacity starts to decline because the foam that is normally used in the midsole gradually gets compressed. BASF researchers have solved this problem with a new open-cell foam that provides the same running shoe characteristics and offers longer-lasting shock absorption. Thanks to small openings in the cell walls of the polyurethane foam (PU), shown in the picture, the midsole can be manufactured so that under pressure it remains stable over a much longer period of time. The low density posed a particular challenge for the researchers: the material must not only be stable and absorb shocks, it also has to be extremely light. Biomechanical tests carried out by Chemnitz University of Technology confirmed that PU with enhanced shock absorption improves the quality of the running experience compared with conventional running shoes. When joggers walk on air, it’s because at BASF, we create chemistry.
