Constructed with Lenzing FR fiber, the socks combine natural flame-resistant properties with moisture-wicking comfort for extended wear during high-performance driving or trackside duty. The large fitted sizing ensures a secure, non-slip fit inside racing boots and driving shoes without bunching, while the black colorway matches standard racing apparel. The SFI 3.3 rating guarantees compliance with professional motorsport regulations and provides the thermal barrier necessary during accident scenarios where extreme heat exposure is a legitimate risk.

The pair format delivers the full set needed for consistent rotation during training and competition schedules.

SFI certification remains the gold standard in motorsport safety regulation. When paired with fire-resistant suits, gloves, and helmets, these socks complete the thermal protection layer system required by sanctioning bodies and recommended by safety experts for anyone working in racing environments where ignition risks exist.
