The Crosstrex series combines the performance features you need in a work boot with the comfort of an athletic-style hiker. Tackle long shifts and tough jobs with long-lasting cement construction and rugged Crosstrex 360 outsoles for superior grip. These static dissipative (SD) boots are designed for technical work environments like computer chip manufacturing plants – when in contact with properly grounded floors, Crosstrex can safely discharge static build-up. Plus, non-metallic parts provide additional peace of mind when working around any live voltage.
