Sidi Sixty Road ShoesCreated to mark Sidi's 60th anniversary, the Sidi Sixty Road Shoes deliver you Italian made quality, a refined aesthetic and modern cycling performance. And being Sidi, we'd expect these to be going strong in sixty years too. A Classic in the MakingMixing cutting edge cycling technology with a timeless aesthetic and with Sidi's well-earned reputation for durability, the Sixty Road Shoes are an outstanding choice for the most demanding of cyclists. The upper benefits from being made from Sidi's TechPro Microfibre. This highly functional material is an eco-friendly leatherette offering a supple and comfortable fit while maintaining superb durability as well as offering water-resistance for damp days. Areas of nylon mesh provide a boost to breathability and airflow, ensuring your hot days on the bike don't leave your feet damp and uncomfortable. An anti-mould treatment also helps fight the build-up of bacteria, leaving your feet fresh, kilometre after kilometre. Tecno-4 closure systemIt was in 1988 that a rotor closure system first appeared on Sidi shoes and this style of closure has been a feature ever since. The very latest Tecno-4 closure system is, of course, leaps and bounds beyond that original system, offering a superbly precise adjustment of the fit. Smooth running wire laces pull evenly to apply just the right amount of pressure. The release of the tension has been improved for faster closure and release. Like all Sidi shoes, this new Tecno-4 is replaceable, allowing your shoes to last and last.As well as the Tecno-4 system, the Sixty makes use of high-security Velcro strap across the front of the shoe. With integrated teeth that lock together when the strap is closed, this system creates a secure fit while keeping weight low and ease of use high.Vent Carbon SoleThe low weight and stiffness of the Vent Carbon Sole allow for high performing power transfers. Put the power down and revel in an instant reaction as you quickly get up to speed. The woven carbon fibre construction maximises the soles stiffness while allowing for a small degree of flex in the toes. This carefully honed flex biomechanically relieves stress on the plantar tendon and helps promote circulation. The sole is also designed with summer in mind, featuring an integrated vent and air channels to dissipate heat and improve airflow.A replaceable polyurethane heel pad and replaceable and adjustable front vent give your shoe excellent breathability and durability.Integrated HeelTo the back of the shoe, the fully integrated heel system provides a secure fit and prevents deformation even during prolonged use. The anatomic shape hugs the heel area, preventing slippage when under load and stabilising the foot for a smooth pedal stroke. When making all-out efforts, sprints and hitting the climbs, this extra stability is essential. Lastly, a reflex insert provides greater safety by helping signal your presence to other road users in low light conditions. Cleat GuidanceThese Road Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact Features:Please Note: Sidi recommend purchasing one whole size up from your usual fitModel to mark Sidi's 60th anniversaryTechPro upperTecno-4 closure systemHigh-security Velcro strapFull 3k carbon Vent soleHandmade in Italy3-bolt cleat compatibleBuy Sidi from Chain Reaction Cycles, the World's Largest Online Bike Store.

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.
