An outsole 1 comprises a high hardness portion 7 and a hardness portion 9. A hardness Ha of the high hardness portion 7 which is measured by a durometer of a type A is 75 to 100. A hardness Hb of the low hardness portion 9 which is measured by the durometer of the type A is equal to or more than and is less than 75. A value of (Ha/Hb) is 1.07 to 2.00. An area ratio of the high hardness portion 7 occupying a bottom e of the outsole 1 is 10% to 90%. An area ratio of the low dness portion 9 occupying the bottom face of the outsole 1 10% to 90%. The sum of the area ratio of the high hardness portion 7 and that of the low hardness portion 9 is 80% or more.
