The Shimano SH-RX800W (RX8) is a featherweight gravel racing shoe built for women who demand the best on mixed terrain. A stiff carbon composite sole delivers direct power transfer from pedal stroke to gravel, while the women's-specific last and surround upper wrap your foot in a precise, comfortable fit that lasts all day. Designed for SPD pedals, the RX8 transitions naturally from bike to hike and back again.

Highlights

  • Carbon composite sole: Super stiff and lightweight construction maximises power transfer with every pedal stroke, rated at the top of Shimano's stiffness scale.
  • BOA® IP1 closure: Single dial with dual micro-adjustment zones lets you dial in mid-foot and upper tension independently for a precise, custom fit.
  • Women's-specific last: Narrower heel and lower volume last provides a natural, supportive fit tailored to women's foot shape.
  • Surround upper: Synthetic leather and mesh construction wraps the foot for a glove-like hold with all-day comfort and ventilation.
  • TPU lugs: Lightweight, abrasion-resistant rubber lugs strike the ideal balance between off-bike walkability and on-bike pedalling efficiency.
  • Heel Stabilizer: Cradles the heel firmly to eliminate slipping and improve power delivery at every cadence.
  • Extended cleat adjustment: 20 mm fore-aft adjustment range gives you more flexibility to dial in your SPD cleat position.
  • Silvadur antimicrobial lining: Keeps the shoe fresh on long days in the saddle.

Comfort & Fit

The Dynalast sole geometry optimises the toe-spring angle and load distribution across the foot, reducing hot spots even on long gravel epics. The anatomic insole includes adaptable arch pads to suit a range of foot profiles. The perforated mesh upper promotes airflow to keep feet cool when the pace picks up.
