With 2,000 nitrile rubber nubs per square foot, Anderson's Flex-Tip Outdoor Mat is excellent at scraping soil from shoes. The mat is so tough that it works great even when placed outside doors to your lobby, office or warehouse. OSHA-compliant beveled edges and deep wells hold the debris and keep it from being tracked across your floors. The mat is 5/8 inches thick, so it also works well as an anti-fatigue mat. Just hose off or shake to clean.
