The Sidi Sixty is a very special cycling shoe to mark the 60th anniversary of the Italian brand. Handcrafted in Italy, the Sixty is a new take on Sidi's timeless style. With a lightweight chassis and cutting edge materials, the high performance shoe has already made appearances in the pro peloton. The Vent Carbon sole has been meticulously engineered for excellent power transfer, with flex introduced into the front end of the sole for long lasting comfort. A built-in vent can be opened and closed (with a Phillips screwdriver), making the Sixty comfortable in British conditions as well as the heat of Italy and ensuring all-season comfort. The Tecno-4 closure system is remarkably advanced compared to the first Sidi rotor closure system designed in 1988 and is the latest in Sidi's all-Italian technological closure system. The mechanism consists of a single rotor to reduce the weight of the shoe and ensure a precise micrometric closure. The tension release has been improved for faster closing and release. Like all Sidi shoes, this new Tecno-4 is replaceable if damaged, while the same goes for the rubber heel. In addition to the rotor system, the Sixty also features a high security Velcro strap on the front of the shoe with integrated teeth that lock when the strap is closed, creating a more secure fit and taking the load. The Sixty's upper is made from TechPro microfiber. This innovative and eco-friendly faux leather offers durability, stability and water repellency. An anti-mold treatment helps fight bacteria build-up, while the nylon mesh of the upper allows for great breathability and creates an ideal microclimate inside the shoe for all-day comfort. There are also Velcro tabs on the inside to keep the tongue perfectly in place. The heel is a fully integrated design, which has been reinforced to prevent deformation during prolonged use and to provide additional support. Anatomically shaped heel stabilizes the foot and helps prevent heel slippage - essential for more difficult climbs, sprints and efforts. A Reflex insert offers greater safety by helping to signal your presence to other road users in poor visibility. The Sixty embodies Sidi's illustrious history and pedigree, while being ideal for the demands of modern driving and racing. These shoes represent Sidi's relentless drive to deliver and create the ultimate in road shoe design, giving you gorgeous style as well as performance.
