Men's Siberian CSA 8" Composite Toe Waterproof Insulated Work Boot - A63PU

These boots are called Siberian for a reason. Ready to help you stay toasty, they’re constructed with 600 grams of insulation that helps provide cold-weather comfort and heat retention. The OrthoLite O-Therm aerogel-infused footbed helps create a thermal barrier underfoot, helping to block cold and regulate temperature. They’re certified to temperatures as low as -40C/-40F and feature oil and slip resistant all-weather TPU outsoles with deep lugs to help add traction for trekking through mud and snow. There’s a breathable and moisture-wicking flannel lining, non-metallic shank to help with structural support, and cement construction that helps deliver flexibility and durability and flexibility.
