SIDI Rex Air Boots

SIDI Rex Air Boots

The Rex Boot from SIDI, constructed of cooling, perforated Technomicro base material and thoroughly tested by SIDI's own Moto-GP riders, is a highly technical, class-leading sport boot.

Equipped with SIDI's exclusive Tecno-3 Push Closure System, the Rex Boots eliminate traditional buckles and laces. Instead, the boots are secured by three separate and adjustable steel cable closures. Each closure is comprised of a circular dial and push button that allows the dial's arm to be lifted and rotated for increased closing pressure.

Limiting lateral movements, the Rex Boots feature a single ankle support brace that combines with the internal and external ankle joint for additional support. Additionally, the bottom of the ankle brace is equipped with air vents which can be operated by an aerodynamic button. The Rex's toe slider also features an optional vent operated by a sliding mechanism located towards the front of the boot.
