Do Shimano shoes run small, and what does Wide mean?

Shimano's own advice: cycling shoes are meant to be form-fitting and on the snug side, so if you are between sizes, size up. Measure your foot length standing with your heel against a wall and use the chart in the size guide. Wide sizes keep the same length and sole but add roughly 9–10 mm of circumference around the ball of the foot — the answer if the length is right but the forefoot pinches.

S-PHYRE RC903 or RC703?

Shimano says the RC703 uses the same S-PHYRE fit technology as its pro road shoes, with a low stack height midsole, Power Zone lace guides and dual BOA L6Z dials. The RC903 steps up to two low-profile BOA Li2 dials, the anti-twist heel cup and a micro-fibre leather upper. The RC703 also comes in wide sizes from 40 to 50, which is often what decides it.

Cooler, drier feet

Vents ahead of the cleat mount channel air through the open structure of the midsole to keep feet drier.

Rapid drying

Drainage ports at the front and rear of the sole let water out, so feet stop sloshing and dry faster.

Flat forefoot contact

A flat contact point under the forefoot spreads pedalling force more evenly for stable pedalling and acceleration.

Two BOA L6 dials

A pair of compact BOA L6 Type Z dials for a precise fit.

Crossover lacing

A slim, low-profile crossover lacing pattern that secures the forefoot.

Breathable synthetic leather

A breathable synthetic leather upper with extra ventilation, shaped for fit.

DYNALAST

Shimano's cycling-specific last, the form that sets the shoe's shape and volume. Shimano says it secures the foot to reduce power loss at the pedal and fatigue on long rides, while an optimised toe spring reduces tension in the feet, calves and hamstrings. The Wide version adds volume around the ball of the foot on the same sole.

How to measure

Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe and measure the distance in centimetres. Measure both feet and go by the longer one.
