The invention provides a pair of sports shoes and a preparation method thereof and relates to the technical field of shoes. The pair of sports shoes is prepared from, by weight, 250-280 parts of natural rubber, 100-200 parts of butadiene styrene rubber, 50-100 parts of polyurethane rubber, 600-700 parts of rock flour, 60-80 parts of zinc oxide, 3-5 parts of stearic acid, 4-8 parts of sulphur, 10-14 parts of ointment, 16-24 parts of floating beads, 16-40 parts of aerogel, 40-60 parts of formalized polyvinyl alcohol fiber, 29-35 parts of aromatic polyamide fiber, 5-9 parts of foaming agent, 3-7 parts of rubber accelerator, 3-5 parts of plasticizer, 7-9 parts of light stabilizer, 3-9 parts of heat stabilizer, 2-6 parts of lubricating agent and 4-8 parts of coupling agent. The preparation method includes the following steps that 1, raw materials are weighed; 2, the raw materials are put in a rubber mixing mill; 3, upper molds, bottom molds and shoe trees are manufactured; 4, foaming molding is performed; 5, the shoe trees, the upper molds and the bottom molds are taken out. The problem that existing sports shoes easily break and have heavy weight, poor toughness and poor heat preservation and insulation effect is solved.
