The Italian-made Fi'zi:k R3 SL Uomo shoes represent the very best in quality, construction and materials. Designed for racing and competition with a lightweight platform, power-boosting technologies and premium comfort details. Fi'zi:k's high-modulus carbon fiber outsole achieves the ideal balance of stiffness and flex by combining maximum power transfer with snug, yet elastic support and fit at the heel. Perforated Microtex upper is breathable, resilient and water-repellent, plus it conforms to your foot's shape for enhanced stability. EVA insole, padded tongue and foam ankle padding adds a ton of comfort which you'll appreciate on longer rides. High-strength Sail Cloth straps resist weather and stretching, so they'll endure years of abuse.
