Claim 4

A ski boot as defined in claim 2 which includes an inner insulated boot adapted to receive a foot of the skier, said inner insulated boot fitting in and being laterally movable inside said outer boot.

Claim 5

A ski boot as defined in claim 3 wherein said inner insulated boot rests upon said insert.

Claim 6

A ski boot as defined in claim 3 wherein said insert is attached to the bottom of said inner insulated boot.

Claim 7

A ski boot as defined in claim 3 wherein said insert is disposed inside said inner insulated boot.

Claim 8

A ski boot as defined in claim 2 wherein said outer boot has a sole, said sole being substantially rectangular and having a top surface and a bottom surface, said sole being longitudinally aligned with and attached to the bottom of said upper shell, said insert resting upon that portion of said top surface of said sole inside said outer boot when said insert is in place.

Claim 9

A ski boot as defined in claim 7 wherein said insert is substantially foot shaped having an upper surface and a lower surface, said insert having a rear balance point disposed on said lower surface at one end and a pair of front balance points disposed on said lower surface opposite said rear balance point, all said balance points contacting said top surface of said sole when said insert is in place and not tilted.

Claim 10

A ski boot as defined in claim 7 wherein said insert is substantially foot shaped having an upper surface and a lower surface, said insert having a substantially central ridge longitudinally disposed on said lower surface, said ridge contacting said top surface of said sole when said insert is in place.

Claim 11

A ski boot as defined in claim 2 wherein said outer boot has a sole, said sole being substantially rectangular and longitudinally aligned with and attached to the bottom of said upper shell, said sole having a bottom, a compartment section extending inside said outer boot from said upper shell to said bottom.

Claim 12

A ski boot as defined in claim 10 wherein said insert is comprised of a substantially rectangular plate of smaller dimensions than said compartment section, said rectangular plate being pivotally supported inside said compartment section so that said rectangular plate can laterally tilt with respect to said ski.

Claim 13

A ski boot as defined in claim 2 wherein said insert is comprised of a series of compressible cylindrical sections, said cylindrical sections positioned adjacent to and longitudinally aligned with each other, each cylindrical section containing a compressible spring, said insert being covered with a flexible cloth and disposed inside said outer boot in such a manner that said cylindrical sections are vertically aligned with respect to said ski.

Claim 14

A ski boot as defined in claim 2 wherein said insert is comprised of a left compartment and a right compartment, said compartments containing a fluid, said compartments being longitudinally aligned and separated by a substantially centrally disposed dividing wall, said central dividing wall having at least one fluid duct which allows said fluid to pass between said compartments, said compartments having a pair of movable covers hinged at the top of said central dividing wall, said normally horizontal covers being tiltable and capable of reducing and increasing the volume of said compartments respectively thereby forcing fluid from out of one of said compartments and into the opposite compartment.

Claim 15

A ski boot as defined in claim 13 wherein said insert is disposed in said ski boot so that said foot of said skier rests upon said covers of said compartments and the inversion and eversion of said foot causing said covers to tilt.

Claim 16

A ski boot as defined in claim 7 wherein said insert is comprised of a flexible sling, said sling being attached to the inside of said upper shell of said upper boot so that said foot of said skier, when in said ski boot, rests inside said sling and is supported above said top surface of said sole by said sling when said insert is not tilted.

Claim 17

An insert for use with a ski boot having a sole, said insert comprising a foot supporting plate-like portion adapted to support a skier's entire foot, said plate-like portion being shaped so as to laterally tiltably fit inside the ski boot and rest upon and substantially cover the sole, and said plate-like portion having means arranged to permit lateral tilting of the foot with respect to the boot and the sole upon inversion or eversion when said plate-like portion is in place inside the boot, said insert having a rear balance point disposed on said lower surface at one end and a pair of front balance points disposed on said lower surface opposite said rear balance point, said front pair of balance points being nonlongitudinally aligned.

Claim 18

An insert for use with a ski boot having a sole, said insert comprising a foot supporting plate-like portion adapted to support a skier's entire foot, said plate-like portion being shaped so as to laterally tiltably fit inside the ski boot and rest upon and substantially cover the sole, and said plate-like portion having means arranged to permit lateral tilting of the foot with respect to the boot and the sole upon inversion or eversion when said plate-like portion is in place inside the boot, said insert having a rear balance point disposed on said lower surface at one end and a pair of front balance points disposed on said lower surface opposite said rear balance point, said front pair of balance points being nonlongitudinally aligned.

Claim 19

An insert for use with a ski boot having a sole, said insert comprising a foot supporting plate-like portion adapted to support a skier's entire foot, said plate-like portion being shaped so as to laterally tiltably fit inside the ski boot and rest upon and substantially cover the sole, and said plate-like portion having means arranged to permit lateral tilting of the foot with respect to the boot and the sole upon inversion or eversion when said plate-like portion is in place inside the boot, wherein said insert is comprised of a series of compressible cylindrical sections, said cylindrical sections positioned adjacent to and longitudinally aligned with each other, each cylindrical section containing a compressible spring, said insert being covered with a flexible cloth and disposed inside said outer boot in such a manner that said cylindrical sections are vertically aligned.

Claim 20

An insert for use with a ski boot having a sole, said insert comprising a foot supporting plate-like portion adapted to support a skier's entire foot, said plate-like portion being shaped so as to laterally tiltably fit inside the ski boot and rest upon and substantially cover the sole, and said plate-like portion having means arranged to permit lateral tilting of the foot with respect to the boot and the sole upon inversion or eversion when said plate-like portion is in place inside the boot, wherein said insert is comprised of a series of compressible cylindrical sections, said cylindrical sections positioned adjacent to and longitudinally aligned with each other, each cylindrical section containing a compressible spring, said insert being covered with a flexible cloth and disposed inside said outer boot in such a manner that said cylindrical sections are vertically aligned.
