Ski boot with a normalized sole

Claim 2

A ski boot having a sole and foot portion constructed for comfortable walking when a wearer is not engaged in skiing, a normalized sole attachment separate from the ski boot and being of a size, shape and hardness to be engageable with substantially any ski binding but rendering normal walking during non-skiing activity difficult and uncomfortable, rigid means peripherally around said upper above said sole portion, further rigid means peripherally around said sole attachment for complementary engagement with said first rigid means, and means on the ski boot and normalized sole attachment having interengagement for releasably securing the attachment to the ski boot.

Claim 3

A ski boot formed of injected plastics material comprising an upper having a sole portion constructed for comfortable walking when a wearer is not engaged in skiing, said upper having a rigid peripheral projecting step spaced above said sole portion, a normalized sole attachment separate from the upper and being of a size, shape and hardness to be engageable with substantially any ski binding but rendering normal walking during non-skiing activity difficult and uncomfortable, said normalized sole attachment having an upstanding marginal wall portion including a rigid upper edge complementary to said rigid peripheral projecting step for reciprocal engagement therewith, and means on the upper and normalized sole attachment having interengagement for releasably securing the normalized sole to the upper.

Claim 4

A ski boot formed of injected plastics material comprising an upper having a sole portion constructed for comfortable walking when a wearer is not engaged in skiing, said upper having a rigid peripheral projecting step spaced above said sole portion, a normalized sole attachment separate from the upper and being of a size, shape and hardness to be engageable with substantially any ski binding but rendering normal walking during non-skiing activity difficult and uncomfortable, said normalized sole attachment having an upstanding marginal wall portion including a rigid upper edge complementary to said rigid peripheral projecting step for reciprocal engagement therewith, and means on the upper and normalized sole attachment having interengagement for releasably securing the normalized sole to the upper.

Claim 5

A ski boot as defined in claim 2, and the sole portion of the upper having a bottom anti-slip profile, and the top surface of the normalized sole attachment having an anti-slip profile complementary to the anti-slip profile of the sole portion of the upper.

Claim 6

A ski boot having a sole and foot portion constructed for comfortable walking when a wearer is not engaged in skiing, a normalized sole attachment separate from the ski boot and being of a size, shape and hardness to be engageable with substantially any ski binding but rendering normal walking during non-skiing activity difficult and uncomfortable, means on the ski boot and normalized sole attachment having interengagement for releasably securing the attachment to the ski boot, and said means comprising an attachment strap on the normalized sole attachment near its front, the foot position of the ski boot having a transverse groove across its top near the toe and thereof adapted to receive said strap releasably, rigid means peripherally around said upper above said sole portion, further rigid means peripherally around said sole attachment for complementary engagement with said first rigid means, and substantially rigid transverse interlocking elements on the normalized sole attachment and boot near the heel end thereof.

Claim 7

A ski boot having a sole and foot portion constructed for comfortable walking when a wearer is not engaged in skiing, a normalized sole attachment separate from the ski boot and being of a size, shape and hardness to be engageable with substantially any ski binding but rendering normal walking during non-skiing activity difficult and uncomfortable, means on the ski boot and normalized sole attachment having interengagement for releasably securing the attachment to the ski boot, and said means comprising an attachment strap on the normalized sole attachment near its front, the foot position of the ski boot having a transverse groove across its top near the toe and thereof adapted to receive said strap releasably, rigid means peripherally around said upper above said sole portion, further rigid means peripherally around said sole attachment for complementary engagement with said first rigid means, and substantially rigid transverse interlocking elements on the normalized sole attachment and boot near the heel end thereof.

Claim 8

A ski boot as defined in claim 1, and said attachment including an upstanding marginal wall portion adapted to receive therein the sole and foot portion of the ski boot to lock the same relative to the normalized sole attachment.

Claim 9

A ski boot as defined in claim 1, wherein the sole of the ski boot includes a bottom anti-slip profile and the upper surface of the normalized sole attachment includes an anti-slip profile complementary to the anti-slip profile of the ski boot sole.

Claim 10

A ski boot as defined in claim 6, wherein said anti-slip profiles comprise a plurality of traverse grooves.

Claim 11

A ski boot as defined in claim 3, wherein said anti-slip profiles comprise a plurality of traverse grooves.
