Socks FR XX-Large 14-15 Black SFI 3.3

The Socks FR XX-Large 14-15 Black SFI 3.3 from RACEQUIP are professional-grade fire-retardant socks engineered for motorsports competitors, industrial workers, and tactical professionals who demand protection in high-heat environments. Designed to meet SFI Foundation 3.3 certification standards, these socks provide a critical layer of thermal defense without compromising comfort during extended wear. The XX-Large sizing accommodates sizes 14–15, ensuring proper fit for larger feet where standard offerings often fall short.

Constructed from fire-retardant cotton blend material, the Socks FR XX-Large 14-15 Black SFI 3.3 deliver inherent flame resistance rather than chemical treatments that degrade with washing. The SFI 3.3 specification certifies these socks meet rigorous thermal protection requirements, including vertical flame spread and after-flame performance benchmarks established by the SFI Foundation. The black colorway resists visible wear and maintains a professional appearance in competitive and occupational settings. Proper sock construction in high-heat applications reduces blister formation and moisture accumulation, extending comfort during multi-hour exposure.

Racing drivers, pit crew members, and workers in thermal environments benefit most from SFI-certified foot protection as part of a complete fire-suit system. These socks pair seamlessly with RACEQUIP race suits and fire-retardant undergarments to create comprehensive coverage against flash fire hazards. The XX-Large 14-15 size ensures compliance with racing sanctioning body requirements that mandate SFI-rated protection from head to toe. For motorsports competitors preparing for track days, endurance racing, or sanctioned events, pairing these socks with SFI-approved race suits is essential for both safety certification and thermal confidence.
