The Walero 2.0 Socks (WAL40003) carry FIA 8856-2018 homologation alongside SFI 3.3. FIA 8856-2018 is the updated standard that replaced FIA 8856-2000, so these socks sit on a newer and stricter specification than the Walero top, long johns and balaclava, all three of which are approved to the 2000 standard.
The 2.0 designation reflects a redesigned construction built around the specific demands of the pedal box. A compression knit runs through the arch for fatigue support across long stints. Targeted padding sits over the ball of the foot, which takes the load on the brake and clutch pedals. The upper is ventilated to reduce heat build-up from the racing boot and firesuit cuff. None of that construction appears in a plain Nomex sock; it is what separates a foot-specific performance garment from a basic compliance item.
Outlast phase-change microcapsules are woven into the yarn, as they are across the Walero range. Feet cycle through heat from the pedals and boot, then cool during safety car periods; the Outlast material moderates that cycle. Walero’s Envirotech+ antimicrobial treatment is built into the fabric at production.
Three size options: XS, S/M and M/L, in Cool Grey or Petroleum. At £56 these sit at the premium end of fire-resistant socks. They are worn by professional drivers across IndyCar and the European Rally Championship, and the FIA 8856-2018 homologation covers any series that requires the updated standard as well as those that still reference FIA 8856-2000.
We hold these at the showroom; lead time is typically 1 to 2 working days. If you want to confirm your series accepts FIA 8856-2018 for socks, or need help with sizing, drop us an email or click to open a chat.

Do I actually need FIA underwear?
If your championship requires it, this is the layer scrutineers ask about, and it is strongly recommended under any suit regardless. These socks are homologated to FIA 8856-2018, the current FIA standard, so the label is there when scrutineers ask for it. They also carry SFI 3.3 approval for events run to American SFI rules. Our guide on whether fireproof underwear is mandatory covers the rules championship by championship.
What size should I go for?
Sizes run from M/L to XS. Underwear layers should sit close to the skin without pinching, as loose fabric wrinkles under the suit and gets uncomfortable fast. Between sizes, take the smaller one for a base layer.
How do I wash it?
Underwear layers are the one bit of racewear you should wash after every use: cool and gentle, no bleach or fabric softener, air dry. That keeps the suit itself needing far fewer washes. Full routine in our racewear care guide.
