The R4B like the R3B and R5B is a neutral fitting shoe designed to accommodate most foot shapes but in addition, features Fizik’s ‘Volume Control’ approach to comfort and Power Transfer. By utilising both a traditional twin-strap velcro lower closure in combination with a Boa upper closure it is possible to dial in both elements to optimise fit for every rider. Adjusting the two straps closest to the toe alters the fit and distributes pressure around the foot, enhancing comfort and performance. Adjusting the BOA dial will alter the fit of the heel cup around the foot, increasing power transfer and maximising performance.
As you might expect, the outsole construction sits between the R5B and R3 Aria and is made from Injection Composite Carbon. Stiffer than the Nylon of the R5 but a touch heavier than the uni-directional carbon of the R3B, the R4B sole offers a great balance of stiffness, comfort and weight for the improving / endurance rider.
The upper is constructed from laser perforated Microtex much the same as the R3B. In addition to lending a fresh look to the shoes, Microtex is remarkably durable, relatively easy to keep clean and helps keep the weight of the shoe to a minimum whilst improving ventilation.
The upper Boa IP1 closure sits to the outside of the shoe and each dial is used to independently adjust and tighten the upper part. This allows for micro-adjustable tailoring of the shoes’ fit while the off-set nature of the upper, means that aerodynamics are optimised. Boa closures have been around for several years and their ability to spread pressure over a broader area ensures less numbness and keeps blood flow around the foot from being restricted, as is often the case with ratchet and strap variants.
