Article of footwear comprising dandelion foam latex materials

A method of manufacturing a dandelion latex shoe component. Dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed together to form a first mixture. The dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed at a temperature not less than 60&#xb0; Celsius and not greater than 80&#xb0; to form the first mixture. Silicon dioxide is then mixed with the first mixture to form a second mixture. The silicon dioxide is mixed with the first mixture at a temperature not less than 80&#xb0; Celsius and not greater than 100&#xb0; Celsius to form the second mixture. The dandelion latex shoe component is then formed from at least the second mixture via a molding process.
