Millennium 3 Sole:
Sidi have designed a sole that improves on the technical characteristics of the previous nylon sole. Constructed from injected carbon fibre in a nylon matrix, the blends provides 36% more rigidity than the Millennium 2 sole. The Millennium 3 sole is also more durable and less susceptible to changes in stiffness resulting from prolonged usage and changes in temperature. It is compatible with the best road pedals on the market. To facilitate cleat replacement, the Millennium 3 sole features a 10mm horizontal and vertical cleat alignment scale moulded into the sole as well as the Look Memory Eyelet.
Soft Instep 2 Closure System:
The wide, anatomical and padded strap has been reduced and coupled to soft, thermo-formed material increasing comfort and performance. It distributes pressure evenly over the arch area, adjustable from both sides for perfect centering. The system eliminates the need for the High Instep Extender. Used with SL and Caliper buckle straps. Serviceable and replaceable.
The micrometric closure called Caliper buckle is regulated by lifting the central buckle. In order to completely open, lift together both side buckles, while to slightly loosen the closure during the race the central clip must be lifted.
Velcro Security System: High security Velcro with integrated locking polymer teeth that engage onto each other when the strap is closed. This feature makes the closure more secure and the Velcro becomes unmoveable.
Replaceable Heel Cup:
A replaceable spare part that prolongs shoe life way past that of the competition.
