The R1 Uomo Shoes are the top offering from the Italian craftsmen at Fi'zi:k. Handmade in Italy, the R1 checks all of the boxes with a moldable insole, an advanced carbon fiber sole design, and ultra-soft, kangaroo leather uppers. Basically, the R1 provides your feet with the lightest comfort available to mankind.
The R1 Uomo features two hook-and-loop straps along with Fi'zi:k's Hex/MC carbon fiber ratcheting buckle. This system allows you to fully tune the fit and volume of the shoes both pre-ride and on-the-fly. The bottom two straps control the snugness of the fit at the metatarsal and instep areas. These straps are best adjusted before you hit the road and left alone thereafter.
The ratcheting strap is what dictates the entry and exit adjustments. The loading lever is made from carbon fiber that's been mated to a stainless steel base. It has a double-click adjustment capability with a full-release mechanism at the base of the lever. Together, the three strap system eliminates any internal foot slippage that depreciates your efficiency. To evenly distribute pressure across the top of the foot, Fi'zi:k made the strap dimensions wide. The strap design allows you to easily lengthen or shorten the strap in order to precisely dial-in the volume of the shoe. Also, each strap has been crafted from fully-adjustable length sail cloth in order to bolster durability while maintaining a low overall weight. For an extreme control over volume, or simply to efficiently clean the inside of the shoe, Fi'zi:k designed the tongue pad to be fully-removable.
To further control slippage, the R1 Uomo has shaped the heel cup at the aft position of the shoe. This feature keeps the foot in the perfect position on hard up-strokes and while climbing out of the saddle. As a result, you're powering the pedals comfortably and efficiently. This has been further heightened by a variable stiffness sole construction. The base layer is an ultra-stiff carbon fiber plate. Second layer has been positioned closer to the heel. This layer is constructed from a material called Tepex that's a little more malleable than the carbon fiber in order to accommodate and support multiple heel and arch sizes. Encompassing both of these layers is a polyurethane Mobius rail that strikes the ideal balance between elasticity and rigidity. Together, the multiple layers work hand-in-hand with the insole and 3D upper to keep the heel in place and to maximize comfort.
And on the subject of the R1's comfort, Fi'zi:k has gone to another level with its 3D Flex Insole design. This insole is heat moldable and fully customizable for the three areas of the foot -- the longitudinal arch, metatarsal button, and the heel cup. To develop this, Fi'zi:k teamed up with Sidas Technologies of France for the design process, and three materials were decided upon. At the metatarsal and longitudinal arches, the insole features the Podiaflex material. Podiaflex was selected for the arch, because its highly moldable properties allow it to perfectly support and conform to your arches. To absorb road vibration and chatter, Fi'zi:k placed Ortholite along the pedal axle portion of the insole. This material is a low-rebound foam and has been cut to the average size of pedal. Having this in place nearly eliminates the numbness generated from long miles clipped-in on the road. Finally, encompassing the heel cup, we the solid and supportive, thermoplastic known as Transflux. Working as a system, we see that the 3D Flex design evenly distributes pressure on the foot, or as Fi'zi:k says, 'the insole is supportive, not corrective or obtrusive.'
The Fi'zi:k R1 Uomo Shoes are available in the colors Black and White and in odd and even sizes ranging from 40.0 to 48.0. Please go to Fi'zi:k's official website for instructions on how to mold the 3D Flex Insoles.
