If you want to start your PU safety shoe production line or upgrade your existing factory, this is one of the key manufacturing processes you must know about. What Does \u201cDual Density\u201d Mean? In general terms, \u201cdual density\u201dmeans the shoe sole is made from two different polyurethane (PU) layers, differing in density and purpose. The upper layer (the actual midsole) is softer and flexible, designed to give comfort, shock absorption and reduce fatigue for long hours of standing and walking. The bottom layer (the outsole) is harder and tougher, meant for wear, [&hellip;]"}
