Abstract
Abstract This ski boot is intended for properly and automatically positioning same on the ski without any preliminary adjustment of the safety binding in the longitudinal direction, irrespective of the boot size. The boot comprises a sole truncated at either end so as to provide a ski-engaging bottom bearing surface having a constant length independent of the boot size, the middle point of the sole being adapted to register with a reference mark carried by the ski; the end faces of the truncated sole are provided with recesses, cavities, grooves or projections adapted to co-operate with corresponding elements of the toe-end and heel-end devices of the safety binding.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
65 words
A ski boot for detachable engagement with a ski, said ski boot comprising: a sole unitarily and non-detachably disposed on said boot and truncated at its front and rear ends so as to provide a bottom bearing surface having a constant length irrespective of the boot size, whereby said bottom bearing surface is adapted for direct contact alternatively with the ground and with the ski.
Claim 2
Dependent Claim
65 words
A ski boot for detachable engagement with a ski, said ski boot comprising: a sole unitarily and non-detachably disposed on said boot and truncated at its front and rear ends so as to provide a bottom bearing surface having a constant length irrespective of the boot size, whereby said bottom bearing surface is adapted for direct contact alternatively with the ground and with the ski.
Claim 3
Dependent Claim
38 words
A ski boot as claimed in claim 1, wherein the distances between the front and rear ends of the truncated sole, on the one hand, and the middle point of the boot, on the other hand, are constant.
Claim 4
Dependent Claim
53 words
A ski boot as claimed in claim 2, wherein the distances between the front and rear ends of the truncated sole, on the one hand, and the middle point of the boot, on the other hand, are equal, said middle point being intended for registering with a reference mark carried by the ski.
Claim 5
Dependent Claim
44 words
A ski boot as claimed in claim 3, wherein the front and rear ends of said truncated sole are provided with means adapted to co-operate with matching members of safety binding devices secured to the ski surface for retaining the ski boot in position.
Claim 6
Dependent Claim
43 words
A ski boot as claimed in claim 4, wherein said means provided at the front and rear ends of said truncated sole consist of recesses adapted to be engaged by matching boot-retaining elements of the corresponding boot-engaging devices of the safety ski binding.
