1. A length- and width-adjustable boot comprising:
a rearward base piece (BP) including a left rearward inner rail (BPr1) and a right forward inner rail (BPr2), the rearward base piece (BP) having a shape of an inverted isosceles trapezium, the left rearward inner rail and the right forward inner rail have an inclination with respect to an axis of symmetry of the boot with an angle α determined by a length/width ratio of a foot comprised between 0° and 90°;
a forward base piece (BA) having a left forward inner rail (BAr3) and right forward inner rail (BAr4), the forward base piece (BA) having a shape of an inverted isosceles trapezium, the left forward inner rail and the right forward inner rail are perpendicular to the axis of symmetry of the boot;
a right-side piece (LR) with a bottom end having a first rail (LRr2) on a first side and a second rail (LRr4) on a second side, wherein the first rail (LRr2) slides into the right forward inner rail (BPr2) of the rearward base piece and wherein the second rail (LRr4) slides into the right forward inner rail (BAr4) of the forward base piece;
a left-side piece (LL) having at a bottom end a first rail (LLr1) on a first side and a second rail (LLr3) on a second side, wherein the first rail (LLr1) of the left side piece slides into the left rearward inner rail (BPr1) of the rearward base piece (BP) and wherein the second rail (LLr3) slides into the left inner rail (BAr3) of the rearward base piece (BA);
a one-piece fixing device runs through the forward base piece and is screwed into the rearward base piece, the one-piece fixing device moves the rearward base piece (BP), the forward base piece (BA), the left-side piece (LL) and the right-side piece (LR) simultaneously, so that a movement of any one of the rearward base piece (BP), the forward base piece (BA), the left-side piece (LL), or the right-side piece (LR) produces a simultaneous movement to adjust a width and a length of the boot in the other three of the rearward base piece (BP), the forward base piece (BA), the left-side piece (LL), and the right-side piece (LR).
