Abstract: An insert for footwear which has improved durability and pliability and satisfies a thumb test of pliability when exposed along the sides of the footwear. The insert comprises a compressible core at least partially surrounded by a flexible casing. The flexible casing has an open window of a size which is sufficient for insertion of the compressible core into the flexible casing but leaving sufficient material to hold the compressible core. The peripheral portion of the flexible casing is spaced from at least a portion of the peripheral surface of the compressible core, while not interfering with the foot applying pressure to the compressible core. A method for making the insert is also provided.
