The multi-layer insole for a shoe is fitted permanently or removably to the shoe and has two sections (20, 22) of a thin, flexible foil of weldable plastic. Said sections are secured together at the edge, forming a hollow space (26), and are bonded together by means of an easily handled welding device in at least one local closed region (32) to form a chamber in the hollow space (26). There is a fluid (28) in the hollow space (26) and in the at least one chamber.
