The Zamberlan Meister GTX RR S3 boot pairs an aluminum toe cap that absorbs impact from falling objects with a Kevlar insole that guards against punctures underfoot. A Hydrobloc(R) Perwanger(R) leather upper pairs with a GORE-TEX(R) Performance Comfort lining to keep feet dry through wet, demanding conditions, while a Vibram(R) Schwarzwald anti-static outsole holds traction on industrial surfaces. A full rubber rand adds another layer of protection where the boot takes the most abuse on the job. What Our Gearhead(R) Experts Are Saying:"The Backpacking Fit locks my heel down and wraps snug through the flex point, so my foot stays put through a full shift on uneven ground. It's light enough that by hour eight, I forget I'm wearing a safety boot at all."
