The invention relates to a sports boot (1) for walking or cross-country skiing, with a flexible shaft (2) receiving the foot, and a reinforcement (5) surrounding the shaft (2) on its external side by sections and being connected with the outsole (3). The shaft (2) is formed in this connection by a cushioned inner boot (6), and a coat (8) of fabric o some other material compatible with the skin. The reinforcement (5) is formed by a latticed or net-like support structure (12) for the inner boot (6), and composed of flexible ribbon elements (13) having, however, the highest possible tensile strength, and being made of plastic or textiles, said ribbon elements resting against external part sections of the inner boot (6), or surrounding the inner boot (6) on its external side within part sections. In this connection, the latticed or net-like support structure (12) is variable with respect to its delimiting or receiving volume as required by means of a lacing system (14). In addition, a soft overstocking (16) is formed, which surrounds the latticed or net-like support structure (12) at least by sections, and serves there for sealing or shutting off the interior of the boot versus external environmental influences.

The invention claimed is: 1. A sports boot for walking or cross-country skiing, with a flexible shaft receiving the foot, and a reinforcement surrounding the shaft on its external side by sections and connected with an outsole, wherein the shaft is formed by a cushioned inner boot consisting of foam plastic and a coat of fabric or another material compatible with the human skin; that the reinforcement is formed by a latticed or net-shaped support structure for the inner boot, and by flexible ribbon elements made of plastic or textiles with high tensile strength, said ribbon elements resting against external part sections of the inner boot, or surrounding the inner boot on its external side within part sections, the latticed or net-shaped support structure being variable by means of a lacing system with respect to its defining or receiving volume; and that a soft overstocking is formed, the latter enclosing the latticed or net-shaped support structure at least by sections, and is formed for sealing or shutting off the interior of the boot against external environmental influences; wherein the latticed or net-shaped support structure is comprised of at least one anchoring element formed on the inner side of the boot, at least one anchoring element is formed on the outer side of the boot, and at least one instep or foot pressure plate at least approximately bridges the lateral anchoring elements; at their ends facing away from the upper support surface of the outsole, the lateral anchoring elements are provided with reversing devices for a string-or lace-shaped pulling element of the lacing system, or form such reversing devices; at least one reversing device for a string-or lace-shaped pulling element for the lacing system is formed and arranged in each of the lateral edge sections of the instep or foot pressure plate associated with the anchoring elements; the lacing system connects the instep or foot pressure plate with at least one of the lateral anchoring elements via a string-or lace-shaped pulling element in a zigzag or undulated form; the latticed or net-shaped support structure is comprised of at least two components and expandable transversely to the longitudinal axis of the boot, and its delimiting or receiving volume is increasable, so that the inner boot can be lifted from the latticed or net-like support structure and removed therefrom as required; and the lateral anchoring elements are provided with adequate rigidity so as to project upwards in an unstressed condition substantially perpendicularly to a support surface for the inner boot. 2. The sports boot according to claim 1, wherein during walking movements, the inner boot is supported with limited relative mobility relative to the upper support surface on the outsole and relative to the ribbon elements. 3. The sports boot according to claim 1, wherein the lacing system connects the lateral anchoring elements and the instep or foot pressure plate with each other in such a manner that the receiving volume delimiting said elements is reducible when the lacing system is pulled tight. 4. The sports boot according to claim 1, wherein for varying the spacing between at least one of the lateral anchoring elements and the instep or foot pressure plate resting on the top side of the inner boot, the lacing system is arranged laterally of the instep or foot pressure plate bridging the foot. 5. The sports boot according to claim 1, wherein in the cross-section, the instep or foot pressure plate is arched transversely to the longitudinal axis of the boot. 6. The sports boot according to claim 1, wherein based on the support surface for the inner boot on the outsole, the instep or foot pressure plate is arched in a concave form, or has end sections extending upwards vis-��-vis the center section. 7. The sports boot according to claim 1, wherein the instep or foot pressure plate has a plurality of breakthroughs or cuts, or is latticed or net-shaped. 8. The sports boot according to claim 1, wherein the instep or foot pressure plate has a plurality of weakened sections. 9. The sports boot according to claim 1, wherein the lateral anchoring elements project by about 2 to 8 cm beyond the support surface. 10. The sports boot according to claim 1, wherein two lateral anchoring elements in the center third of the longitudinal extension of the support surface are connected with the outsole. 11. The sports boot according to claim 1, wherein the instep or foot pressure plate and the lateral anchoring elements are formed by an injection-molded components consisting of an elastic and rebounding plastic. 12. The sports boot according to claim 1, wherein with respect to the longitudinal extension of the support surface, in its rear third or in the heel section an additional anchoring element is secured on the outsole on each of the two sides of the longitudinal axis of the boot. 13. The sports boot according claim 12, wherein the two additional anchoring elements are connected with one another via a curved connection element guided curved around the rear heel section. 14. The sports boot according to claim 1, wherein a heel pressure plate for admitting pressure to the rear heel section is formed in the section below the Achilles tendon. 15. The sports boot according to claim 14, wherein the heel pressure plate is connected with tensile strength to the rear end of the outsole via a holding element. 16. The sports boot according to claim 13, wherein the connection element is connected with the lateral edge sections of the heel pressure plate, or designed in the form of one single piece, and guided around the external side of the heel pressure plate. 17. The sports boot according to claim 13, wherein the vertical spacing between the curved connection element and the support surface on the outsole is changeable or fixable or adjustable. 18. The sports boot according to claim 17, wherein an adjustment means for the connection element comprises ribs and recesses on the external side of the heel pressure plate spaced from one another in the vertical direction. 19. The sports boot according to claim 14, wherein the heel pressure plate is formed by a central, vertically extending holding bridge connected with the outsole, and two pressure distribution wings laterally protruding therefrom. 20.
