How to choose your size

If you’re a standard road rider fit: Stay true to size (EU size you normally wear in Giro, S-Works, or Shimano RC).

If you’re between sizes: Go up half a size, especially if you prefer comfort over race compression.

If you have wider feet: This is not a forgiving shoe. Consider sizing up or exploring wider-fit options.

If you prefer a tight race fit: Stick true to size — the dual BOA® system allows precise adjustment without pressure points.

Fit feel on foot

  • Close, performance-oriented wrap through the midfoot
  • Dual BOA® Li2 dials evenly distribute pressure
  • Ultra-stiff carbon sole — minimal flex for maximum power transfer
