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 mec...
