Sidi GENIUS X Road Cycling Shoes Black Size 42.5

The GENIUS X in size 42.5 is designed for riders who need a precise fit that sits between standard sizes. This version delivers stability and comfort without pressure, making it ideal for regular training and longer road rides.

The clean black colorway highlights the shoe’s technical and minimalist design. The premium microfiber upper adapts naturally to the foot while maintaining its supportive structure under load.
