Abstract
Abstract An improved slip and/or skid resistant surface is provided for work gloves, work shoes, floor coverings in work areas and the like. The surface of the invention provides a porous gripping surface particularly useful in greasy and oily environments where it is necessary for a workman to be able to grip mechanical devices or loose objects having a coating of oil or grease. The surface of the invention is a foam surface laminated to a substrate. The foam, prior to lamination, may be foamed with varying amounts of air depending upon the degree of abrasion resistance required. The foaming may be by mechanical or chemical means.
