SH-RC810

• Intended use: Premium road racing and training shoe with technology derived from the S-PHYRE RC910.
• Sole and performance: Carbon sole with a low-stack SPD-SLR platform supports efficient transfer of power.
• Upper: Ventilated, lightweight synthetic leather.
• Closure: Two BOA Li2F dials provide fine adjustment and distribute closure tension around the foot.
• Fit technology: SHIMANO DYNALAST 2.0 gives the forefoot and toes more room while reducing toe spring. The official fit choices are Narrow, Standard and Wide.
• Stability: An integrated heel stabilizer helps retain the foot during acceleration.
• Cleat interface: Expanded SPD-SLR positioning range with alignment markings.
• Sizing guidance: Compared with the earlier DYNALAST, Standard has extra toe space and Wide has substantially more volume. Narrow provides a lower-volume option. Available sizes differ by color and fit.
