Fi'zi:k's innovative designs and top-shelf materials are putting a fresh face on cycling shoes. The R3 SL Uomo Shoes is no exception. Building on the existing R3 platform, the SL Uomo forgoes kangaroo leather for a full MicroTex upper. This rendition satisfies the vegan cyclist and weight watchers alike, while still creating one of the lightest and stiffest shoes on the market.
The R3 SL features a three hook-and-loop strap closure system. 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, and the top strap controls the entry/exit point. 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 R3 SL 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 topic of comfort, Fi'zi:k went above and beyond to make the R3 SL extremely breathable. The uppers have been constructed from the same MicroTex synthetic leather that graces Fizik's bartape. This material keeps your feet breathing and comfortable on long summer days in the saddle. And for the insole, Fi'zi:k included its own Dual Density Eva. And while its not custom moldable like with the R1's 3D-Flex, it does incorporate a thoughtful design that assures comfort by absorbing road vibration and supporting your arch system.
The Fi'zi:k R3 SL Uomo Shoes are available in even and odd sizes from 40.0 through 48.0 and in the color Silver.
