Abstract: The invention is a boot (1; 100) comprising a shaped shell (2; 101) including a rear portion (3; 102) that surrounds the heel (T) of the user's foot (P) and a front portion (4; 103) that develops mainly along a longitudinal axis (X) and surrounds the distal region (D) and the top (S) of the foot (P) and is 5 telescopically associated with the rear portion (3; 102) to which it is connected through fixing means (5). One of the front (4; 103) and rear portions (3; 102) is provided with a plurality of first through holes (6; 104) defining longitudinal axes (Z1; Z?1) that are parallel to each other and separated by a predefined distance (L1; L?1) and are selectively arranged coaxially to second through 10 holes (7; 105) made in the other one of the rear (3; 102) and front portions (4; 103), where they house the fixing means (5), in such a way as to vary the length of the shaped shell (2; 101) by discrete values.
