Ski boot with a normalized sole

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.

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.
