(57) An outsole (1) of a soccer spike shoe is formed of six portions, i.e. a heel portion
(A), a tread portion (B), a toe portion (C), a midfoot portion (D), an arch portion
(E) and a toe root portion (F). The heel portion (A), tread portion (B), toe portion
(C) and midfoot portion (D) are made more rigid, and the arch portion (E) and the
toe root portion (F) are made less rigid. First to fifth studs (31-35) are provided
on a sole surface of the outsole (1). The first stud (31) is disposed at a central
portion of a distal phalanx (DP1) of a first or great toe of a shoe wearer's foot. The second stud (32) is positioned
at a metatarsophalangeal joint (MJ1) of the first toe. The third stud (33) is placed at a head portion of a metatarsus
(MB4) of a fourth toe. The fourth stud (34) is located at a distal phalanx (DP3) of a third toe. The fifth stud (35) is deployed at each head portion of metatarsi
(MB2, MB3) of a second and third toe. Thereby, rigidity and strength as well as bendability
of the outsole can be achieved. Also, slippage on the contact surfaces can be prevented
from occurring during playing soccer.
