Footwear having an elastic correcting strap for treating and preventing foot malpositions
Footwear for treating and preventing foot malpositions, in particular for treating and preventing hallux valgus, comprising a holding element configured for securing a foot relative to the footwear; and a tensioning element configured to be fastened to a toe and configured, in a state in which the footwear is fastened to the foot, to exert a first corrective force on the toe and to exert a second corrective force directed opposite to the first corrective force on a metatarsophalangeal joint of the toe, wherein the tensioning element is an elastic correcting strap.
1. Footwear for treating and preventing foot malpositions, comprising:
a sole comprising an outsole and an insole;
a holding element configured for securing a foot relative to the footwear; and
a tensioning element configured to be fastened to a toe and configured, in a state in which the footwear is fastened to the foot, to exert a first corrective force on a toe and to exert a second corrective force directed opposite to the first corrective force on a metatarsophalangeal joint of the toe, the tensioning element comprising an elastic correcting strap, wherein
the holding element comprises a holding strap and a further holding strap, wherein
the holding strap is configured to, in a state in which the footwear is fastened to the foot, secure at least one further toe being arranged adjacent to the toe, a further metatarsophalangeal joint, or both, relative to the footwear, and
the further holding strap, in a state in which the footwear is fastened to the foot, secures a metatarsal region of the foot relative to the footwear and lies against the foot in the region of its instep, and wherein oppositely arranged end sections of the correcting strap, the holding strap and the further holding strap are guided into the sole and arranged between the outsole and the in-sole and connected thereto in a form-fittingly and/or force-fittingly and/or adhesive manner.
2. The footwear of claim 1 , wherein in the state fastened to the foot, the correction strap is elastically deformed.
3. The footwear of claim 1 , which is configured such that, in the state fastened to the foot, the first corrective force, the second corrective force, or both are generated by a tensioning force prevailing in and induced by elastic deformation of the correcting strap.
4. The footwear of claim 1 , wherein in the state of the footwear fastened to the foot, the correcting strap, along an engaging surface thereof, lies against the toe, the metatarsophalangeal joint, or both, and the correcting strap is elastically deformed along its engaging surface, along portions adjacent to the engaging surface, or both.
5. The footwear of claim 1 , wherein in the state fastened to the foot, the correcting strap, at least in sections, engages around the toe such that the correcting strap extends from one side of the toe to an opposite side of the toe or the metatarsophalangeal joint.
6. The footwear of claim 1 , wherein in the state fastened to the foot, the correcting strap lies against the foot such that the correcting strap extends from a lateral side of the toe along a toe surface to a medial side of the foot in the region of the metatarsophalangeal joint.
7. The footwear of claim 1 , wherein the footwear is configured such that, in the state fastened to the foot, the first end portion is positioned between the toe and an adjacent further toe and the second end portion is positioned in the region of the metatarsophalangeal joint.
8. The footwear of claim 1 , wherein the correcting strap is fixedly connected to a sole of the footwear via the first end portion and the second end portion.
9. The footwear of claim 1 , wherein the second end portion lies sideways against the metatarsophalangeal joint or is arranged in front of or after the metatarsophalangeal joint in a direction (X) pointing from the metatarsophalangeal joint to the toe.
10. The footwear of claim 1 , wherein a connecting portion of the correcting strap, via which the first end portion of the correcting strap is connected to the sole, is arranged spaced apart from a proximal end of a toe interspace between the toe and the adjacent further toe, wherein a distance between the connecting portion and the proximal end of the toe interspace along a longitudinal foot axis (X) lies in the range between 4 mm and 18 mm.
11. The footwear according to claim 1 , wherein in the state fastened to the foot, the holding strap lies against or is arranged in the region of the further toe, or lies against or is arranged in the region of the further metatarsophalangeal joint, or lies against or is arranged in the region of both.
12. The footwear of claim 1 , wherein the further holding strap is an elastic holding strap which is configured to be elastically deformed when the footwear is fastened to the foot.
13. The footwear of claim 1 , wherein the holding strap is formed by a substantially tensile rigid holding strap.
14. The footwear of claim 2 wherein the correction strap is elastically deformable to an extent of at least 3 mm.
15. The footwear of claim 12 wherein the elastic holding strap is elastically deformable to an extent of at least 3 mm.
16. The footwear of claim 8 , wherein the second end portion lies sideways against the metatarsophalangeal joint or is arranged in front of or after the metatarsophalangeal joint in a direction (X) pointing from the metatarsophalangeal joint to the toe.
17. The footwear of claim 10 , wherein the holding element comprises a further holding strap configured for, securing at least one further toe adjacent to the toe, a further metatarsophalangeal joint, or both, relative to the footwear in the state of the footwear fastened to the foot.
