Shimano RC703 Green Sage

Cycling Shoes (Race) Shimano RC703 Green Sage

The Shimano RC7 - Green Sage Are high-end competitive road shoes, directly impregnated with S-phyre DNA. Designed for pure performance, they are aimed at demanding cyclists looking for maximum yield, irreproachable stability and sustainable comfort, even long distances.

With a maximum stiffness index and technologies from the highest level of competition, the RC703 is a reference choice for intensive training as for the race.

Conception and DNA Competition

Inspired by S-Phyre models

The RC703 resume adjustment technology and the design principles of professional S-phyre shoes. Each detail is designed to optimize power transmission, foot stability and high intensity pedaling efficiency.

Breathable and enveloping upper

The breathable synthetic leather upper offers excellent ventilation while maintaining a precise fit. Its enveloping construction reduces the overlapping of material and provides homogeneous maintenance, close to the foot, for a full sensation of control.

Integration Sole / Empower

The seamless integration of the intermediate sole and the upper improves the overall stability of the shoe, while reducing the weight and the parasitic deformations during the maximum stress phases.

Adjustment and maintenance

BOA® FIT System Double L6 System

The BOA® FIT SYSTEM tightening system with two compact dials L6-type Z allows precise micrometric fit on different areas of the foot. It ensures firm and balanced maintenance, perfectly adapted to the requirements of the competition.

Discreet cross lacing

The low profile crossed lacing effectively secures the forefoot while maintaining a refined and aerodynamic aesthetic, faithful to the race.

Heel stabilizer

The built-in heel stabilizer strongly holds the back of the foot, limiting unwanted movements and improving stability during accelerations and sprints.

Power transmission and ventilation

Hollow carbon midsole

The highly rigid carbon fiber composite midsole maximizes power transfer. Its hollow structure promotes air circulation and drainage of water, helping to keep feet cooler and drier.

Ventilation and fast drying

The openings at the front and back of the midsole effectively evacuate air and water. This design reduces moisture accumulation and improves comfort on long outputs or hot weather.

Stiffness index

Stiffness index Shimano : 10, one of the highest levels of the range, for cyclists seeking maximum yield and a pedaling instant response.

Pedal compatibility

SPD-SL compatibility

The Shimano RC703 are compatible with SPD-SL holds, offering a wide support surface and optimum power transmission, even during the most intense efforts.

Recommended pedals

• NA-r8000

Shimano Dynalast Technology

Principle

Shimano Dynalast technology optimizes the shape of the shoe to improve the contact between the foot and the pedal, respecting the natural biomechanics of the cyclist.

Benefits for use

It promotes more fluid pedaling, reduces muscle fatigue and improves overall efficiency, particularly on long outflows and in sustained stress phases.
