A stuffing for inserting into, and maintaining a shape of, a shoe having a curved toe portion, comprising:
- a) an insert extending along a longitudinal axis between a heel region and a toe region, the insert including overlying planar sheets of synthetic plastic material bounding an interior, and a pivot seal for heat sealing the sheets together at a pivot region intermediate the heel and toe regions;
- b) an inlet including overlying planar strips of synthetic plastic material bounding a passage into the interior of the insert through which a gas is admitted to inflate the insert;
- and
- c) the toe region of the insert, after inflation, being bent at the pivot region about a pivot axis perpendicular to the longitudinal axis into an arcuate shape that conforms to the curved toe portion of the shoe.
