Abstract: Method of improving the performance of sports shoes, especially soccer boots, by improving the coefficient of friction of key areas of the shoe (such as the toe box and upper) in both wet and dry conditions. Described are the application of butylene type coatings, including polyisobutylene polymers, to maintain desirable existing characteristics of a shoe, such as feel and feedback, but which improve grip. Variations such as patches, and areas of specific types of fabric or coating, are also discussed.
