Low density, closed cell, {HEAD ~ soft foam products} having dimensional stability are made from ethylenic resins having low stiffness, especially comprising copolymers consisting essentially of ethylene and monoethylenically unsaturated non ionic comonomers, by release to lower pressure of a flowable, foamable gel under pressure, e.g., by extrusion foaming, wherein {TAIL ~ the gel} comprises the ethylenic polymer and a volatile mixed blowing agent
