The footwear further includes a leg strap device and an adjustable tensioning device connected to the leg strap device. A tensioning element is defined with a first end section, a second end section and an intermediate section between the first and second end sections, where the first end section is connected to the foot section, the second end section is connected to the adjustable tensioning device and the intermediate section is provided below, or integrated as part of, an arch section of the foot section. The adjustable tensioning device is connected to the leg strap device. ## Claims ### Claim 1 A footwear for rehabilitation after an ankle sprain or for preventive training to avoid an ankle sprain, wherein the footwear comprises: a sock body comprising a foot section, a leg section, and an ankle section between the foot section and the leg section, the foot section comprising an arch section; a leg strap device; an adjustable tensioning device directly connected on at least one medial side of the leg strap device; a tensioning element having a first end section, a second end section, and an intermediate section between the first and second end sections; and a guide directly connected to the ankle section of the sock body for positioning the tensioning element in relation to the sock body, wherein the tensioning element is disposed between the guide and the sock body; wherein the first end section of the tensioning element is connected to the foot section on the opposite side to the adjustable tensioning device, the second end section of the tensioning element is connected to the adjustable tensioning device, and the intermediate section of the tensioning element is provided below the arch section or integrated as part of the arch section such that the adjustable tensioning device and the tensioning element are configured to provide an adjustable inversion force by adjustment of the adjustable tensioning device; and wherein the adjustable tensioning device and the tensioning element are configured such that the adjustable inversion force forces the foot section towards an inverted position. ### Claim 2 (depends on 1) The footwear according to claim 1, wherein the adjustable tensioning device provides adjustable tensioning of the tensioning element with respect to the foot section of the sock body. ### Claim 3 (depends on 1) The footwear according to claim 1, wherein the tensioning element is at least partially elastic. ### Claim 4 (depends on 1) The footwear according to claim 1, wherein the second end section of the tensioning element is provided at, or adjacent to, the ankle section of the sock body or at, or adjacent to, the leg section of the sock body. ### Claim 5 (depends on 1) The footwear according to claim 1, wherein the leg strap device is connected to the leg section of the sock body. ### Claim 6 (depends on 1) The footwear according to claim 1, wherein the footwear comprises a zipper provided in an upper part of the leg section of the sock body. ### Claim 7 (depends on 1) The footwear according to claim 1, wherein the adjustable tensioning device comprises a reel-based tensioning mechanism. ### Claim 8 A method for rehabilitation of an ankle region after an ankle sprain or for preventive training of an ankle region to avoid an ankle sprain, wherein the method comprises: putting a sock body of a footwear on to the ankle region, wherein the sock body comprises a foot section, a leg section, and an ankle section between the foot section and the leg section, the foot section comprising an arch section; wherein the footwear further comprises: a leg strap device; an adjustable tensioning device directly connected on at least one side of the leg strap device; a tensioning element having a first end section, a second end section, and an intermediate section between the first and second end section; and a guide directly connected to the ankle section of the sock body for positioning the tensioning element in relation to the sock body, wherein the tensioning element is disposed between the guide and the sock body; wherein the adjustable tensioning device is connected on a medial side of the leg strap device, the first end section of the tensioning element is connected to the foot section on the opposite side of the adjustable tensioning device, the second end section of the tensioning element is connected to the adjustable tensioning device, and the intermediate section of the tensioning element is provided below, or integrated as part of, the arch section; tightening the leg strap device of the footwear around a leg area; adjusting the adjustable tensioning device, resulting in an adjustable inversion force that forces the foot section towards an inverted position; and using muscles in the ankle region to counteract the inversion force.
