The Georgia Logger Insulated Gore-tex Steel Toe Work Boot puts the emphasis on safety, durability and performance.

Vibram is the leader in high-performance soling products that are lightweight, long-wearing and flexible. These soles are resistant to abrasions, oils, chemicals, heat and metal chips. Additional durability comes from the Goodyear welt construction which enhances the boot's strength and flexibility. Waterproofing comes from Gore-tex. This fabric is revolutionary: it's waterproof, windproof and breathable. This logger has a steel shank, as well as a covered cushion insole. A polyurethane orthotic insert is removable. Your feet stay warm in this boot. It's infused with 400g of Thinsulate Ultra insulation.
