The invention relates to the technical field of foaming materials, and particularly provides a shoe material composition based on biomass raw materials and a foaming shoe material. The foaming shoe material composition based on the biomass raw material is prepared from the following raw material components in percentage by weight: 0 to 45 percent of bio-based TPAE, 0 to 45 percent of bio-based TPU, 20 to 37 percent of bio-based EVA, 22 to 35 percent of bio-based POE and 5 to 15 percent of compatilizer, the sum of the weight percentages of the bio-based TPAE and the bio-based TPU is 30-45%; the compatilizer is a combination of C12-C36 alkyl-terminated polyester-based polyurethane and C12-C36 alkyl-terminated alkyl polyurethane in a weight ratio of (1: 9)-(9: 1). The shoe material composition has good foaming performance, and the foamed shoe material is high in rebound rate and good in mechanical property. 本申请涉及发泡材料技术领域，具体提供一种基于生物质原料的鞋材组合物和发泡鞋材。基于生物质原料的发泡鞋材组合物，原料组分按100%重量，包含：0~45%生物基TPAE、0~45%生物基TPU、20~37%生物基EV
