Total Claims: 10
Claim 1
Independent Claim
220 words
A shoe liner, comprising: a lower liner layer and an upper liner layer superposed over said lower liner layer; both said upper liner layer and said lower liner layers are each a laminated web and each said web comprises a respective first layer of material which faces toward the said first layer of the other said web and each also comprises a sheath layer on the side of each said web that is away from the other said web, sandwiched between said upper and lower layers is a generally resilient support unit including a support part for supporting the arch of a wearer''s foot; said support unit being arched; said support unit also including a portion extending back to the wearer''s heel bone and shaped to define a trough for the wearer''s heel bone; said first layers being spaced apart to provide space for receiving said support unit which is inserted therebetween; said support unit being secured to said first layers; said layers being dimensioned so as to extend beyond said support unit; said first layers at the portions of said upper and lower liner layers that extend beyond said support unit being normally continuously in engagement with each other, thereby forming a four-layer construction comprising one said sheath layer, both said first layers and the other said sheath layer.
