The Shimano S-Phyre RC910 Shoes featured here at Escapa are high-performance road shoes designed to provide a direct connection to the pedals, precise support, and exceptional stability during intense rides. Their new hollow carbon sole reduces the overall height of the shoe and improves pedaling efficiency. The closure system featuring two BOA Li2F dials, the Japanese microfiber upper, and the Shimano Dynalast 2.0 last provide a snug, customizable fit.
Low-profile hollow carbon sole
The new carbon sole features a hollow internal construction developed to combine stiffness, stability, and light weight. Its profile reduces the distance between the foot and the pedal axle, creating a more direct feel when accelerating, sprinting, or pedaling out of the saddle.
A lower overall profile can help:
- Improve power transfer. Reduce unnecessary foot movement.
- Increased stability during maximum effort.
- Provide a more direct connection to the bike.
- Promote a smooth and efficient pedaling motion.
Developed alongside the SPD-SLR system
The SH-RC910s were developed as part of a complete system alongside the new Shimano SPD-SLR pedals. The sole features an expanded range of adjustment to position the cleats with greater precision and adapt the position to the rider’s biomechanical needs.
This adjustability allows you to modify the cleat’s longitudinal position to properly align the foot, pedal, and bike axle.
Before assembly, it is advisable to check compatibility between the shoes, the cleats, and the specific pedal model. The new Shimano PD-R9300 pedals use the SPD-SLR platform and its specific cleats.
Shimano Dynalast 2.0
The Shimano Dynalast 2.0 last features a wider forefoot area and reduces toe rise. This geometry aims to improve stability and provide a more natural position during long rides and high-intensity efforts.
The Standard fit of this new generation provides more room in the toe box than previous versions. Shimano notes that some riders who previously chose a larger size for extra width may prefer to go down half a size with the new last.
Japanese microfiber upper
The upper is crafted from lightweight, breathable Japanese microfiber. Its construction is designed to evenly wrap around the foot, preventing areas of excessive pressure and maintaining a clean, aerodynamic surface.
The distribution of the material and the BOA closure system ensure that the Talon, arch, and forefoot remain securely held in place during accelerations, climbs, and changes in pace.
Dual BOA Li2F Closure
The closure system uses two BOA Li2F dials with textile laces. Each dial allows for micro-adjustments to tailor the pressure to different areas of the foot and modify the fit even while running. The laces’ wraparound path helps distribute tension across the instep, reducing localized pressure points and maintaining a stable fit.
Carbon-reinforced Talon
The Talon structure incorporates a carbon fiber reinforcement that limits torsion during maximum-power efforts. This construction keeps the foot stable and helps prevent lateral movement inside the shoe.
The increased stability provides a firm foundation for pedaling during:
- Sprints and accelerations.
- Climbing out of the saddle.
- Time trials.
- High-intensity training.
- Road races.
Lightweight
The stated weight is approximately 233 grams per shoe in size 43. This figure may vary slightly depending on size and the manufacturing process. Its light weight, combined with the stiffness of the sole and the BOA closure system, reinforces its focus on competition and high-performance road cycling.
