The Sidi Sixty is a very special cycling shoe to mark the Italian brand’s 60th anniversary. Handmade in Italy, the Sixty is a fresh 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 designed for excellent power transfer, with flex introduced in the front end of the sole for long-ride comfort. An integrated vent can be opened and closed (with a cross head screwdriver), making the Sixty just at home in UK conditions as it is in the heat of Italy and ensuring four season comfort. The Tecno-4 closure system is remarkably advanced compared to the first rotor closure system Sidi designed back in 1988 and is the latest in Sidi’s all-Italian tech closure system. The mechanism consists of a single rotor to reduce the shoe’s weight, and ensures precise, micrometric closure. The release of the tension has been improved for faster closure and release. Like all Sidi shoes, this new Tecno-4 is replaceable if it is ever damaged while the same is true of the rubber heel pad. As well as rotor system, the Sixty also has a high-security Velcro strap across the front of the shoe featuring integrated teeth that lock together when the strap is closed, creating a more secure fit and taking the load. The Sixty’s upper is made from TechPro Microfibre. This innovative and eco-friendly leatherette offers durability, stability, and water-repellency. An anti-mould treatment helps fight the build-up of bacteria, whilst the upper’s Nylon mesh allows 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 avoid deformations under prolonged use and provide extra support. Anatomically shaped, the heel stabilises the foot and helps prevent heel slip – essential for those tougher climbs, sprints and efforts. A Reflex insert provides greater safety by helping signal your presence to other road users in poor visibility. The Sixty embodies Sidi’s illustrious history and pedigree, whilst being ideal for the demands of modern-day riding and racing. These shoes represent Sidi’s ceaseless drive to provide and create the ultimate in road shoe design, providing you with beautiful style as well as performance. Key Features: New model to mark Sidi’s 60th anniversary. TechPro upper Tecno-4 closure system High security Velcro strap Full 3k carbon Vent sole Handmade in Italy
