A toe extroversion correction device includes a support portion integrally formed and made of a soft material, a first toe sheath portion disposed on a lateral side of the support portion, a second toe sheath portion disposed on another lateral side of the support portion, and a protection pad portion protruded from a lateral side of the first toe sheath portion, such that the first toe sheath portion is sheathed on big toe, and the second toe sheath portion is sheathed on the second toe, and the support portion is clipped between the big toe and the second toe to produce an action force to push away the big toe, and the protection pad portion can be attached onto an internal side of a first toe joint of the big toe to prevent the protruding first toe joint of the extroverted big toe from being rubbed with a shoe.
