The invention discloses a cycling cleat sole material resistant to bending fatigue test and a preparation method thereof. The sole material is composed of a polyamide matrix, special nylon, carbon fiber, toughening agent, surface lubricating additive, heat stabilizer and color masterbatch or toner in a certain proportion. The preparation method comprises feeding the polyamide matrix and special nylon through the main feeder, carbon fiber through the side feeder, and toughening agent, surface lubricating additive, heat stabilizer, color masterbatch or toner through the additive feeding port; adding all raw materials into a twin-screw extruder in a certain proportion for melting, extrusion, granulation and drying to obtain the product. In the polyamide cycling cleat sole material of the invention, polyamide 6, polyamide 66, polyamide 6/66 or a mixture thereof is used as the matrix, and carbon fiber is used as the main structural support framework to improve the high flexural modulus of the sole material. The toughening agent ensures that the sole material passes the bending fatigue test. The product of the invention meets the functional and comfort requirements of cycling cleat sole materials.
