Shoe DNA X2 Patriot Size 11.5

The Simpson Safety Shoe DNA X2 Patriot Size 11.5 is a mid-top professional safety shoe engineered for personnel requiring certified fire-resistant footwear in high-heat environments. Built with a leather outer construction and Nomex inner lining, this SFI 3.3/5-rated shoe delivers thermal protection and durability for racing drivers, motorsports crew, and industrial workers operating in controlled-fire zones. The patriotic red, white, and blue colorway combines safety compliance with distinctive styling.

The SFI 3.3/5 certification indicates this footwear meets the Safety Equipment Institute's standards for heat and flame resistance, critical for occupants in vehicles or environments where fuel fires or thermal exposure is a real risk. The Nomex inner layer provides a protective barrier against sudden temperature spikes, while the leather outer maintains structure and abrasion resistance under demanding conditions. Size 11.5 accommodates users seeking precise fit in this specific width and length. At 2.79 lbs per pair, the shoe maintains the weight balance needed for extended wear during multi-hour shifts or training sessions without causing foot fatigue.

This footwear is designed for racing professionals, track personnel, emergency response crews, and occupational safety roles where SFI certification is mandated or strongly preferred. The mid-top profile provides ankle support without restricting movement in vehicle cockpits or tight working spaces. Law enforcement tactical units, military support staff, and industrial safety programs frequently specify SFI-rated footwear to meet liability and regulatory requirements. The DNA X2 Patriot balances regulatory compliance with everyday wearability for users who need certified protection as standard equipment.
