Soft Instep Closure System: The wide, anatomical and padded strap has been reduced and coupled to soft, thermoformed material increasing comfort and performance. It distributes pressure evenly over the arch area, adjustable from both sides for perfect centering. The system elimates the need for the High Instep Extender. Used with SL and Caliper buckle straps, which are serviceable and replaceable.

Caliper Buckle: The micrometric closure called Caliper buckle is regulated by lifting the central buckle. In order to completely open, lift together both sides buckles, while to slightly loosen the closure during the race the central clip must be pushed down.

High Security Velcro: The high security straps with integrated locking polymer teeth engage onto each other when the strap is closed. This feature makes the closure more secure.

Sidi Heel: The reinforced heel keeps the foot in position and avoids the shoe being deformed by extreme performance or prolonged pressure.
