The long-lasting and durable sole of the Black Eagle® line incorporates a special rubber and tread design that provides excellent multi-directional anti-slip grip on many surfaces, even in wet or cold weather. What does multi-directional anti-slip mean for you? It means you can start, stop, and turn on a dime without worrying about losing your footing. The soles are resistant to oil and gasoline, are antistatic, and promises not to mark up your floors. These police boots are airport friendly since Black Eagle® Athletic 2.0 T High Side Zip is entirely metal free too.
