Claim 1

A half-size holder for a disposable warmer for a shoe, and which is substantially immovable in a shoe, the holder comprising: a permeable base member which has a length of about one-half the length of a shoe in which it is to be used, said length of said base member extending from a toe portion of said base member to a rear end portion of said base member, said base member having a widest part intermediate said toe portion and said rear end portion, said rear end portion of said base member being situated at a substantially mid-position between said widest part of said base member and a heel of a shoe; a permeable closure member mounted on said base member so as to overlap said base member, said closure member being joined to said base member along peripheral edges thereof, leaving an inlet-and-outlet opening at the rear end portion of said holder for receiving a disposable warmer through said opening and for permitting insertion and removal of said disposable warmer through said opening; said holder being substantially flat and generally in the shape of a forward or toe portion of a shoe, and said holder being mountable to a sole portion of a shoe at a forward portion of the shoe without extending to the heel portion of the shoe, with the widest intermediate part of said base member being arranged so as to be in substantially a widest part of the forward or toe portion of a shoe; said base member comprising a fabric material layer, and a net member made of plastic material mounted thereon and interposed between said fabric material layer and said closure member, said net member having an irregular construction defining an unevenness along its thickness direction to define spaces so that said base member and said net member hold much air, said net member defining an uneven horizontal surface; said base member and said closure member having permeability values which are different from each other; and said holder having reversible means for providing different heating values to a wearer's foot, said reversible means comprising the holder which is flippable wherein said base member and said closure member have different permeability values.
