There is provided a shoe sole component that has properties such as strength and cushioning property that are suppressed from being changed even under a wide temperature range from severe cold at -10°C or lower to high temperature conditions exceeding 30°C. A shoe sole component includes a cross-linked foam of a resin composition, the resin composition containing a thermoplastic polyolefin resin, in which tan δ [-20°C to 40°C] at a frequency of 10 Hz measured according to JIS K 7244-4 is 0.01 to 0.5, and tan δ [-20°C]/tan δ [40°C] at a frequency of 10 Hz is 0.7 to 1.3. |
