Race-day socks from Shimano's flagship S-PHYRE line, built to chase marginal gains. Thin aerodynamic ribs and a mid-calf cut help you slip through the wind, while targeted arch and heel support keep your feet locked in for stable, efficient pedalling.

Highlights

  • Aerodynamic knit ribs designed to cheat the wind at speed
  • Mid-calf length for a clean, race-ready aero profile
  • Breathable mesh instep vents heat out of the shoe
  • Arch and heel support hold the foot stable while pedalling
  • Reinforced ribbed heel for lasting durability
  • Thin sole knit for a direct connection to the shoe
  • Made with 72% recycled polyester yarn to reduce environmental impact

Aerodynamics

Thin knitted ribs and the mid-calf height are shaped to smooth airflow over the ankle and lower leg, helping you save precious seconds where every watt counts.

Support and fit

Knitted arch and heel support secure the foot inside the shoe so your power goes straight to the pedal, while a reinforced ribbed heel keeps the sock holding its shape ride after ride.

Ventilation

A breathable mesh instep helps vent heat from inside the shoe, and the thin sole knit creates a more direct, connected feel through the pedal stroke.

Compatibility & fit

This is the L/XL size, fitting EU shoe sizes 45 to 48. Colour is White. Suits road and performance cycling shoes; choose the size band that matches your shoe size for the intended snug, supportive fit.
