Abstract:

PCT No. PCT/CA93/00458 Sec. 371 Date May 4, 1995 Sec. 102(e) Date May 4, 1995 PCT Filed Nov. 4, 1993 PCT Pub. No. WO94/09663 PCT Pub. Date May 11, 1994A liner for a sport boot shell and a method for making a custom fitted liner for a sport boot, are disclosed. The liner is designed to be worn inside a boot shell. In a preferred embodiment the liner includes inner and outer of flaps which wrap in opposite directions across a wearer's shin and forms a compound curve in a region in front of the wearer's ankle. The liner including flaps may be made from a single piece of thermoplastic foam material of uniform thickness. The design of the liner prevents the cuff of the liner from loosening around the wearer's shin and calf when the wearer's leg is flexed forward at the ankle. The shell can therefore be worn more loosely than is necessary with a boot liner of conventional design. The liner may be made by making an unfitted liner from a sheet of thermoformable material. The unfitted liner has a forwardly facing opening and wings extending forwardly on either side of opening. The unfitted liner is then heated to above the thermoforming temperature of the material and simultaneously fitted to the shell and the wearer's foot and leg by the steps of: placing the wearer's foot into the unfitted liner; forming flaps by wrapping the wings across the wearer's shin; holding the unfitted liner in place with an elastic stocking; inserting the wearer's foot, the unfitted liner and the elastic stocking into the shell and allowing the unfitted liner to cool.
