Orthopedic device (1) for the treatment of Hallux Valgus (Ha), the device being suitable for wearing footwear, consisting essentially of an elastic sleeve (2) intended to be worn on the foot (P), to exert a localized effect of containment on the metatarsals (M1, M2, M3, M4, M5) of the foot (P), the sleeve comprising: a main part (3) intended to fit with the foot (P) locally at the height of the metatarsals (M1, M2, M3, M4, M5) of the foot, a distal part (5) to cover the big toe (Dg), a connecting band (6) between the main part (3) and the distal part (5), intended for be placed laterally on the foot to request it in traction in order to exert on the big toe (Dg) a lateral force (F2) directed inwards with respect to the plane of symmetry of the human body, and a pad (4) attached on the inner wall of the elastic sleeve (2), creating a localized thickness, the pad being di spuesta to be placed laterally on the foot, locally against the first metatarsal of the big toe (Dg), characterized in that the pad (4, 43) is made of a material (40) that has a friction coefficient such that the pad makes contact with the skin of the foot, without slipping, under the pressure of the containment effect exerted by the sleeve (2), in such a way that it serves as an anchor for the exercise of lateral force (F2), being at least a part of the pad adapted to be arranged in different positions along the first metatarsal of the big toe (Dg) so that the tensile force on the joint band (6) can be adjusted.Dispositivo (1) ortopédico para el tratamiento del Hallux Valgus (Ha), siendo el dispositivo adecuado para llevarlo puesto calzado, compuesto esencialmente por un manguito (2) elástico destinado a llevarlo puesto sobre el pie (P), para ejercer un efecto localizado de contención sobre los metatarsianos (M1, M2, M3, M4, M5) del pie (P), comprendiendo el manguito: una parte principal (3) destinada a encajar con el pie (P) localmente a la altura de los metatarsianos (M1, M2, M3, M4, M5) del pie,
