Waterproof, breathable insulation without excess bulk or stiffness

The Giro Xnetic H2O Waterproof Socks are built to keep your feet dry, warm, and comfortable when riding in wet, cold conditions. Using Giro’s innovative Xnetic™ knit construction, they offer a close, sock-like fit that moves naturally with your foot while maintaining excellent breathability.

A fully waterproof membrane blocks rain, spray, and road splash, while the seamless knit design reduces bulk and pressure points for all-day comfort. The result is a high-performance waterproof sock that delivers reliable protection without sacrificing feel or ventilation — ideal for winter riding, commuting, and foul-weather adventures.

The result is pair of socks that can be worn with nearly any cycling shoe, providing dry warmth and comfort when conditions are less than ideal.

"Super stretch and low bulk make the Xnetic H2O socks easily the best-fitting waterproof socks we've used" - Guy Kestevan, CyclingNews.

XNETIC™ KNIT — Xnetic Knit offers suppleness and breathability; for sock-like comfort and superb ventilation. Xnetic Knit also is DWR-treated for water repellency and easy cleaning.
