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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel toe cap meets impact and compression protection requirements for industrial footwear\u003c\/li\u003e\n\u003cli\u003eSteel midsole provides puncture resistance underfoot\u003c\/li\u003e\n\u003cli\u003eMetatarsal guard protects the top of the foot from falling objects\u003c\/li\u003e\n\u003cli\u003eSure Grip outsole designed for traction on wet and slippery surfaces\u003c\/li\u003e\n\u003cli\u003e16-inch shaft height offers knee-level protection against water and debris\u003c\/li\u003e\n\u003cli\u003eFull rubber construction resists moisture and common job-site contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or direct-purchase knee boot for trade professionals requiring ASTM-class foot protection in wet or hazardous work environments.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Height\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToe Protection\u003c\/strong\u003e: Steel Toe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMidsole\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetatarsal Protection\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutsole\u003c\/strong\u003e: Sure Grip Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpper Material\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpper Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutsole Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIGMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mb816b.11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524947280178,"sku":"MB816B.11","price":251.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/facf033d97141c23ed5075daa51ad799.jpg?v=1785462106","url":"https:\/\/voomisupply.com\/products\/sigma-mb816b-11-steel-toe-rubber-knee-boot-size-11","provider":"Voomi Supply","version":"1.0","type":"link"}
