This footbed is made from soft polyurethane that wil retain its shape and thickness throughout the life of the boot. Heavy-duty, flexible anti-bacterial non-woven insole Directly moulded polyurethane midsole for greater shock absorption. Oil and acid resistan nitrile outsole. Heat resistant to 300°c. The Steel Blue soiling system is a three density soiling system that offers a high level of comfort, shock absorbency and energy return.
