Inner boot for a rigid boot

Abstract

An inner boot able to be inserted inside a rigid boot, which comprises a rear zone having a lower portion, or heel zone, comprising a first insert made of flexible and/or elastic material, to allow an at least partial flexion of the inner boot and to facilitate the insertion and/or removal of a user's foot into/from inside the inner boot.

1 . An inner boot able to be inserted inside a rigid boot, comprising a rear zone having a lower portion, or heel zone, comprising a first insert made of flexible and/or elastic material, to allow an at least partial flexion of said inner boot and to facilitate the insertion and/or removal of a user's foot into/from inside said inner boot. 
   
   
       2 . The inner boot as in  claim 1 , further comprising an upper part, or bootleg, and a lower part, or vamp, substantially made of a first material, wherein said lower part or vamp comprises said lower portion, or heel zone, and wherein said first insert is made of a second material having greater flexibility and/or elasticity than said first material. 
   
   
       3 . The inner boot as in  claim 2 , further comprising a sole coupled with said lower part or vamp, wherein said first insert is disposed just above and/or adjacent to a rear edge of said sole. 
   
   
       4 . The inner boot as in  claim 3 , wherein said upper part or bootleg is able to be selectively positioned in a first position, in which said upper part or bootleg is able to prevent the removal of said foot from inside said inner boot and in which said first insert is substantially not deformed, and in a second position, inclined with respect to said first position, in which said upper part or bootleg is able to allow the insertion/removal of said foot into/from inside said inner boot and in which said first insert is elastically deformed. 
   
   
       5 . The inner boot as in  claim 4 , further comprising an aperture disposed at an upper end of said upper part or bootleg, in order to insert said foot inside said inner boot, wherein said aperture has an area varying at least between a first area, in said first position of said upper part or bootleg, such as to prevent the removal of said foot, and a second area, in said second position of said upper part or bootleg, greater than said first area, such as to allow the insertion/removal of said foot. 
   
   
       6 . The inner boot as in  claim 3 , wherein said first insert is connected partly to said lower part or vamp, and partly to said sole. 
   
   
       7 . The inner boot as in  claim 3 , wherein said first insert extends transversely from said sole and comprises an upper edge connected to said lower part or vamp, and a lower edge connected to said sole. 
   
   
       8 . The inner boot as in  claim 2 , wherein said lower part or vamp comprises a front portion or tongue, comprising a second insert made of a third material having greater flexibility and/or elasticity than said first material, so as to allow the flexion at least of said upper part or bootleg with respect to said lower part or vamp, and to facilitate the insertion and/or the removal of a user's foot into/from inside said inner boot. 
   
   
       9 . The inner boot as in  claim 8 , wherein said second material and said third material are the same. 
   
   
       10 . The inner boot as in  claim 8 , wherein said second material and said third material are different. 
   
   
       11 . The inner boot as in  claim 8 , wherein said first insert and said second insert make a single insert which completely surrounds said foot. 
   
   
       12 . The inner boot as in  claim 3 , wherein said first insert and/or said second insert extend for a pre-determined height of said sole. 
   
   
       13 . The inner boot as in  claim 8 , wherein said first insert and said second insert are separated by a portion made of rigid material. 
   
   
       14 . The inner boot as in  claim 2 , wherein said first insert and said second insert are symmetrical with respect to the longitudinal median axis of said lower part or vamp. 
   
   
       15 . The inner boot as in  claim 8 , wherein said second insert comprises two distinct parts, each disposed on one side of said front portion or tongue. 
   
   
       16 . The inner boot as in  claim 8 , wherein said first insert and/or said second insert substantially constitute the whole of said lower portion or vamp. 
   
   
       17 . An inner boot able to be inserted inside a rigid boot, comprising a front portion or tongue, comprising an insert made of flexible and/or elastic material, to allow an at least partial flexion of said inner boot and to facilitate the insertion and/or the removal of a user's foot into/from inside said inner boot. 
   
   
       18 . A rigid boot, such as for example a ski boot, a snowboard boot, a trekking boot or suchlike, comprising an inner boot as in  claim 1 .
