TINGLEY Sigma Boots MB816B Metatarsal Black Rubber Safety 。Tingley Sigma MB816B rubber metatarsal boots offer heavy-duty protection for industrial environments. These knee-high work boots feature a floating metatarsal guard, steel toe, and steel midsole for comprehensive impact and puncture resistance. Designed with a rear gusset and quick-release buckles for an adjustable fit, they also include retroreflective tape for 360-degree visibility. The sure-grip outsole and abrasion-resistant rubber ensure durability and traction in demanding conditions. Note: These boots are new with tags but show significant white blooming/oxidation on the rubber surface from storage, which is common for natural rubber and does not affect performance. These boots weigh just under 8 lbs and will effect shipping price due to weight.
