Fizik created the R1 road shoe starting with the concept of a shoe hand made in northern Italy constructed of the absolute best materials placed in their ideal location. The upper is made of kangaroo leather and Fizik's famous microfiber that it uses in their saddles. Kangaroo leather in particular has excellent durability combined with a suppleness unmatched by other materials. Stitching is hidden in the Rivoltato style for a very refined look.
The closure system uses two straps made from weather resistant, extremely strong sail cloth tipped with laser printed metal tabs and a ratcheting buckle for precise adjustment. A HexMC® carbon fiber level on the buckle is nothing short of stunning and sits on a stainless steel base. The strap affixed to the ratcheting buckle is adjustable for different foot shapes so you can perfectly dial in how many notches you want left when the strap is at a secure and comfortable tension.
Stiffness and flex of the sole are specifically engineered in 3 areas - dubbed 3D Flex Outsole Technology - for the best combination of power transfer and fit. The center of the sole and cleat area are the stiffest part made from T700 high-modulus carbon for maximum force transfer to the pedals. Around the heel, there is slight amount of flex for positive heel support. Each side is made to have some flex and elasticity to comfortably fit a wide range of heel shapes and sizes.
The R1 features a premium insole with carbon reinforcement round the heel to provide a rigid support structure to align the foot with the body. Low rebound Ortholite foam is used at the metaplate to add cushioning under the ball of the foot. Podiaflex N material made of a polyester resin and can be optionally custom fit to your foot using the SIDAS technologies Flashfit System.
