The invention relates to an orthopedic device for the treatment of hallux valgus, comprising: a main part (3) in the form of an elastic sleeve, intended to exert a local restraining force (F1) on the metatarsals (M1, M2, M3, M4, M5)； a distal part (5) for encapsulating the big toe； a connecting band (6) between the main part (3) and the distal part (5), intended to be tensioned in order to exert a lateral force (F2) on the big toe that is directed inwards in relation to axis Δ of the human body； and a pad (4) secured to the inner wall of the device, creating a localised increased thickness and intended to be positioned against the first metatarsal of the big toe, such as to act as an anchor during the application of the lateral force. The pad can be placed in different positions in relation to the foot, thereby allowing the tensile force on the connecting band (6) to be adjusted. The opposing retaining and lateral forces serve to re-align the articulation during walking.
