The present invention concerns a method for coating outer, internal and inner surfaces of an item of footwear with a water- and/or oil-repellent coating by a low-pressure plasma polymerization coating process, by degassing the item of footwear prior to said coating process. 112-. (canceled)14. Method according to claim 13 , wherein said set low pressure to which the plasma chamber is pumped down claim 13 , is equal to or higher than a set base pressure of the coating step or an optional pre-treatment step.15. Method according to claim 13 , comprising shielding parts of the item of footwear prior to said coating process claim 13 , removing of parts of the item of footwear prior to said coating process claim 13 , and/or separately coating parts of the item of footwear by said coating process prior to assembly of the parts into said item.16. Method according to claim 13 , wherein the low pressure plasma polymerization is preceded by a low pressure plasma pre-treatment step claim 13 , preferably wherein the outgassing and the pre-treatment are combined in a single processing step.17. Method according to claim 13 , wherein the item of footwear is a sports shoe.19. Method according to claim 13 , wherein the low pressure plasma polymerization uses a monomer which is an organosilane claim 13 , wherein the organosilane is:{'sub': 1', '2', '1', '3', '4', '5', '2', '3′', '4′', '5′', '3', '4', '5', '3′', '4′', '5′', '3', '4', '5', '3′', '4′', '5′, 'Y—X—Ywherein X is O or NH, Yis —Si(Y)(Y)Yand Yis Si(Y)(Y)Ywherein Y, Y, Y, Y, Y, and Y are each independently H or an alkyl group of up to 10 carbon atoms; wherein at most one of Y, Yand Yis hydrogen, at most one of Y, Y and Y is hydrogen; and the total number of carbon atoms is not more than 20;'}{'sub': 3', 'q', '2-q', 'n, 'cyclic according to —[Si(CH)(H)—X—]— where n is 2 to 10, wherein q is 0 to 2 and wherein the total number of carbon atoms is not more than 20;'}{'sub': 2', '1', '2', '3', '4', '1', '3', '1', '2', '3', 't', '2t+1 ...
