Boot Height: Approx. 16'' Tall. Designed to protect in muddy, grimy job sites, these boots are made of ZXT, a premium rubber compound with high-tensile strength for tear resistance and durability. A top strap buckles for an adjustable, secure fit. The chevron-cleated outsole supplies traction and won't track mud or dirt. This boot features a ribbed vamp to resist snagging, a heel counter to prevent slippage, and a fiberglass shank for lightweight support.
