Provided is a foot joint supporter which can push up the wearers plantar arch to support the formation of the medial longitudinal arch, thus improve the walking performance of the wearer, increase the stability of the food joint, reduce fatigue of the triceps surae muscle, and relieve pain in the Achilles tendon, triceps surae muscle and the outside of the foot joint (ligament). The foot joint supporter (10) comprises a first anchor section (2) for tightening the wearers lower thigh with a tubular knitted fabric, a second anchor section (3) for tightening the wearers instep and sole with the tubular knitted fabric, and a knitted figure eight section (4) between the first anchor section (2) and the second anchor section (3), being composed of a foot section (11) and a body section (12) and supporting the wearers talocrural joint, wherein said food section (11) is composed of an instep section (11a) covering the wearers instep and a sole section (4a) covering the wearers sole, and the stretch resistance, in the length width direction of the tubular knitted fabric, of the sole section (4a) is larger than the the stretch resistance, in the length width direction of the tubular knitted fabric, of the instep section (11a).La présente invention concerne un dispositif de support darticulations du pied pouvant soulever larche plantaire du porteur pour assurer le support de la cambrure longitudinale médiane, et donc améliorer lefficacité de marche de lutilisateur, accroître la stabilité de larticulation du pied, réduire la fatigue du muscle triceps sural, et soulager la douleur dans le tendon dAchille, du muscle triceps sural et de lextérieur de larticulation du pied (le ligament). Le dispositif de support darticulations du pied (10) comporte une première section dancrage (2) pour serrer la partie inférieure de la cuisse du porteur avec un article tricoté de forme tubulaire, une seconde section dancrage (3) pour serrer le cou-de-pied et la plante du pied avec larticle tricoté
