Sidi RR Wire 2

The outer material is made of microfibre. Microfibre is breathable, temperature-regulating and dirt-repellent thanks to its surface texture. Soft Instep 4: The Soft Instep Closure System is a wide, anatomically shaped strap combined with a soft, thermoformed EVA pad that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable from both sides to place the EVA pad perfectly over the instep. Soft Instep Closure System 4 is replaceable and available as a spare part. Tecno 3 Push Single: The central mechanism, Single tecno-3 Push System, creates a perfect balance of tension between the inside and outside of the shoe. The symmetrical mechanism guarantees excellent closure and adaptation to every instep. With the ?Push? button on the twist lock allows the adjustment wing to be opened, making adjustment while riding even easier. Like most Sidi small parts, the Tecno 3 Push Single System is interchangeable. Tecno 3 push system: The Tecno 3 system extends over the entire length of the shoe and thus enables optimum pressure distribution. The upper material adapts perfectly to the shape of the foot thanks to the new system. Sidi's reliable fastening system has been further improved and, thanks to the new cable material, allows quick and easy adjustment. The system can be lifted with a small button on the twist lock, making it even easier to adjust while riding. Like most Sidi small parts, the Tecno 3 system is replaceable. Adjustable heel retention device: The adjustable heel cup system additionally reinforces the area at the Achilles tendon of the shoe and improves heel retention, as the system closes securely around the rider's ankle and prevents it from slipping out of the shoe.
