Abstract: A watertight sock with vent holes for use when cleaning is made from, for example, rubber, latex, or nitrile. Vent holes provide for sufficient ventilation. Elastics, knotting, or extra stretchable material provide for the sock to stay in place. Anti-skid material provides that the wearer does not skid. A cut provides for snug fit on the foot, and a flossy inside provides that the sock is easy to put on and take off over textile or skin.
