The Sidi Men’s Prima Mega Road Shoe is designed for the modern rider. The Prima is easy to wear and adjust thanks to its Firmor closure and lightweight upper built to reduce foot fatigue. Its low-profile carbon nylon Aerolite Sole is engineered for efficient power transfer for sprinting with enough flex and comfort for long rides. Plus the Sidi Mega Last provides Sidi fit and performance to riders who have slightly wider feet.
