<p><P>PROBLEM TO BE SOLVED: To provide footwear capable of reducing problems of moisture resistance and heat leak and securing high insulation performance for ages in the foot wear applying a vacuum heat-insulating material to a shoe sole part. <P>SOLUTION: This footwear applies the vacuum heat-insulating material 31, which is formed by covering a plate-like core material 32 having two opposite heat transmission faces, with multilayer-structured exterior cover materials with gas barrier property to decompress the inside of the external cover materials and tightly seal it, to at least either part of a shoe sole part. In the vacuum heat-insulating material 31 applied to the shoe sole part, the gas barrier layer of the external cover material in the shoe sole side is formed by aluminum evaporation 34, the gas barrier layer of the external cover material in the sole side is formed of aluminum foil 36 and a plastic film is disposed in the surface on the shoe sole side of the vacuum heat-insulating material 31 as the cover member. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
