PROBLEM TO BE SOLVED: To provide an insole equipped with a protrusion which supports a natural walking exercise while preventing hallux valgus from occurring, at the front section of the insole, and shoes equipped with the insole. SOLUTION: When the front leg section is kicked out, by a first protrusion 25, the great toe and the os metatarsales 4a and 4b of the second toe are supported. Thus, the metatarsophalangeal articulations 13 is supported, and the short flexor muscle 71 of the great toe, the long flexor muscle 72 of the great toe and the long flexor muscle 74 for toes are supported. Thus, the lateral arch of the foot section is supported, and the windlass is increased. Therefore, the motility of toes can be improved while keeping the rigidity of the foot. Since the first protrusion 25 is formed into an approximately half-moon shape when seen on the plane, the great toe and the second toe can be naturally separated along the shape of toes. Also, the stable supporting of the great toe and the second toe can be easily obtained.
