Protect your shoes—and your environment—with AMMEX® Shoe Covers. Made of 100% spun-bond polypropylene, these “booties” help keep your work area clean from dirt introduced by shoes, and protect your shoes from spills, drips, dust, dirt, and contaminants. AMMEX Shoe Covers are available in blue in two sizes: universal, equivalent to men’s sizes 10.5 and smaller, and extra large, equivalent to men’s sizes larger than 10.5.
