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