The name 'Diadora' is derived from the Greek 'dia-Dorea,' which means 'to share gifts and honors.' And while we doubt that Cadel is ever going to share his 2011 Tour victory with anyone other than his teammates, with Diadora's release of the Jet Racer Shoes, you're at least able to share the same shoes that propelled him to the top spot on the podium.
Starting with the uppers, Diadora built the Jet Racer shoes around its Shape Race last. This fit forms precisely to your foot, combining just the right amount of arch support with a solid forefoot and midfoot hold. Additionally, this last works to secure heel retention as well. This comfortable cradle on the foot is achieved using the Diadora's Suprell-Tech and Morpho Cage AM design. Essentially, this is a supple leather/thermoplastic polyurethane (TPU) composite and lightweight mesh 'space frame' construction that supports pedaling motions with its ultra-stable and breathable composition. At the heel cup, Diadora designed the Jet Racer to perfectly contain the rider's foot in its seat by armoring the delicate Achilles tendon with a two-part composition. For structural rigidity, the pre-molded TPU heel cup uses a firm composite around the back, with softer and more flexible plastics along the sides. The result is a light profile that supports the heel down in the cup, while remaining flexible enough to provide the lateral 'give' necessary for out of the saddle pedaling efforts.
The Jet Racer closure system works in complete harmony with this last, as its multifaceted retention system targets specific locations of the foot. Over the forefoot, a single hook-and-loop strap controls the volume lower down in the shoe. Diadora calls it a 'Safety Closure,' as it keeps the shoe from opening in the event that either of the remaining straps fail during a race. Stepping up from that, Diadora added its Quick Adjustment closure. On first glance, it looks like a traditional hook-and-loop strap, that is until you see the mechanical aluminum lever. This represents the Diadora attention to detail in full effect. This buckle closure locks the strap in place, eliminating any worries of rain and mud affecting the strap's retention. Bu, as your race ensues and your feet begin swell, a slight push to the buckle's top releases tension on the strap. This small movement provides an instant, and much needed, relief to your foot.
Underneath the strap, Politech and shock absorbing EVA inserts were added in order to aid in both pressure distribution and shock absorption. Rounding out the closure system at the shoe opening is the Multifit Adjust strap. This patented locking system allows you to further customize the fit of the shoe with respect to the morphology of your individual foot shape. This is accomplished by first selecting one of three strap positioning holes on the inside of the shoe in order to center the EVA-backed strap evenly over the top of your foot. You then locate your desired retention setting with the Micro CL buckle. This micro-metric aluminum closure ratchets to your desired retention setting, yet it simply releases with a raised push-button on the buckle's outer surface. Once again, a simple but effective design. The durable mechanical buckle opens on a rocker for easy cleaning, and it's able to be replaced in the event of a crash.
Diadora chose to mate the Jet Racer upper to its Carbon Technology Racer outsole. This full-carbon platform incorporates its new NET Breathing System, which is a network of synthetic fibers that have been molded around a breathable and waterproof membrane. This patented ventilated design allows an increased capacity of rider perspiration, while preventing moisture, mud, and other external elements from penetrating the sole and getting into the shoe. The design of the sole also keeps stack height and weight to a minimum, while maintaining incredible rigidity for a direct transmission of power to the pedals.
The heel pad is made of a firm replaceable rubber compound known as Duratech, which provides excellent surface grip and high abrasion resistance. Hi-Vent 100% waterproof insoles complete the Jet Racer shoes, giving you maximum support, ventilation, and comfort in all weather conditions.
The Diadora Jet Racer Shoes are available in odd and even sizes ranging from 37.0 to 47.0 and in the colors Black/yellow fluo, Red Fluo/black, White/silver/black, and Yellow Fluo DD/black/silver.
