Patent ID: 8869434

Claim:
Boot, comprising: a shaped shell including a rear portion that is suited to surround at least the heel of a wearer's foot, and a front portion that develops mainly along a longitudinal axis, is suited to surround at least a distal region of said foot, and is telescopically associated with said rear portion, to which it is connected through fixing means, wherein a bottom of said front portion presents first essentially parallel longitudinal arms having corresponding first longitudinal channels defined by interspaces between said first longitudinal arms, wherein the first arms and first channels extend in a plane that is essentially parallel to the longitudinal axis, wherein a bottom of said rear portion presents second essentially parallel longitudinal arms having corresponding second longitudinal channels defined by interspaces between said second longitudinal arms, wherein the second arms and second channels extend in a plane that is essentially parallel to the longitudinal axis, wherein said first longitudinal arms match said second longitudinal channels and said second longitudinal arms match said first longitudinal channels, defining an interleaved coupling among said arms and said channels, essentially in a single longitudinally-extending plane forming at least a portion of a smooth inner surface of the bottoms of the front and rear portions, and wherein said first and second longitudinal arms are provided with a plurality of respective first and second through-holes, traversing said longitudinal arms and defining longitudinal axes that are parallel to each other and separated by a predefined distance, suited to be selectively arranged coaxially to pair one or more first through-holes with corresponding second through-holes, wherein said first and second through-holes are suited to receive said fixing means, in such a way as to vary a length of said shaped shell by discrete values.
