Sigma mb816b.11 Steel Toe Rubber Knee Boot Size 11

Product Description

The SIGMA mb816b.11 is a steel-toe rubber knee boot built for trades professionals who work in wet, muddy, or chemically active environments. Standing 16 inches tall with a black rubber upper and black outsole, this boot is engineered for foot and lower-leg protection on demanding job sites. It includes a steel toe cap for impact resistance, a steel midsole for puncture protection underfoot, and metatarsal guarding for added coverage across the top of the foot. The Sure Grip outsole provides traction on slick or uneven surfaces. Size 11.

This boot is suited for plumbing, utility, landscaping, agricultural, and general construction applications where standing water, debris, or chemical exposure is a routine hazard. The full rubber construction resists moisture penetration, making it appropriate for trench work, drainage installation, irrigation service, and similar trade scenarios where standard work boots fall short. The knee-high shaft height keeps water and contaminants out during wading or prolonged outdoor exposure.

Installation Notes

No installation is required for this product. Inspect the boot for integrity before each use, particularly around the sole-to-upper bond and the toe cap seam. Boots with steel protection components should be stored away from prolonged exposure to extreme heat, which can degrade rubber compounds. Confirm that the selected size and protection rating meet applicable jobsite PPE requirements before use.
