Good to know
The Pro Leader v4 shares many features with its predecessor, the Pearl Izumi Pro Leader v3. Both of these road cycling trainers use the same type of stiff outsole with replaceable heel pads, a Look-style cleat system, and vents for aeration.
Most of the updates occurred up top. The upper of the Pro Leader v4 sports a more straightforward design with an all-black colorway. It does, however, feature a pop of color on its outsole. The closure is now placed at an angle for a pleasurable riding experience.
Pedaling efficiency. The bottom of the Pro Leader v4 is made of 1:1 Integrated Carbon Power Plate. This compound is light yet very stiff. The rigidity makes for better pedaling motion as it doesn’t easily bend, reducing power loss.
Enhanced visibility. The outsole has been treated to electroplating as marked by the mirror-like finish in some areas. This element amps up both the style factor of the shoe and the rider’s visibility.
The Pro Leader v4 has three holes to accommodate the use of a Look-style cleat system. This road cycling trainer is compatible with the following pedals: Look Keo Blade, Time Xpresso 10, and Shimano Dura-Ace PD-R9100, to name a few.
Comfort. The top of this Pearl Izumi cycling shoe is made of a 3-layer Seamless Composite. It has no stitches inside that could cause blistering or chafing. The material is soft and breathable, ensuring in-shoe comfort at all times.
Lockdown. Atop the tongue is two BOA dials. They can be micro-adjusted using 1mm increments and can quickly be released by popping up the dial. The use of two dials evenly distributes the pressure on the instep to avoid any discomfort as the cables get tighter.
The ‘T’ structure at the back serves as a heel cup. It keeps the rearfoot steady while pedaling and also prevents unnecessary heel lifts.
Two features in this cycling footwear enhance the fit. The first is the Zero Distraction Upper Fit, which puts the lacing system in a slanted orientation to avoid discomfort in the soft tissue of the instep.
The second is the Zonal Bi-directional construction of the closure. It aids in securely wrapping the foot. Both features contribute to the snug, customized fit of the top.
A 1:1 Insole System can be found inside the Pearl Izumi Pro Leader v4. What makes it different from other insoles is that it has slots for wedges. These foam components improve support and cushioning under the ball of the foot and the arch.
