[Problems] To provide an interdigital pad to be fitted on toes, so that interdigital pad portions are positioned between adjacent toes, to produce a firmly-standing force, to produce a force for holding the pad by toes, and to correct the standing posture and walking posture so as to keep a proper or good posture in walking and in exercise. [Solution] An interdigital pad for toes, made of an elastomer material having elasticity and flexibility, characterized by a larger diameter engaging ring part to be fitted on the big toe and providing an interdigital pad portion positioned between the first toe and the second toe, a smaller diameter engaging ring part to be fitted on the fourth toe and providing an interdigital pad portion positioned between the third toe and the fifth toe, a base part connecting said engaging ring parts and to be positioned on the sole of the foot, a projected part functioning as an interdigital pad portion when the projected part is fitted between the second toe and third toe, and being caught by the second tor and third toe, said base part and two engaging ring parts forming an arched edge which contacts with the roots of respective toes, and a thickness of a lower ring portion of said larger diameter engaging ring par and a thickness of the base part of the second toe being thicker than a thickness of a portion located from the third toe to the fifth toe, so that a height from the floor surface at a side of the little toe and forth toe is a little higher than at a side of the big toe.
