Sidi Rex Air Men's Street Boots

The SIDI Rex Air Boot delivers the perfect balance of protection and airflow, making it a top choice for riders who want race-level performance with street-ready breathability. Its perforated upper and integrated mesh panels enhance ventilation throughout the boot, keeping your feet cool and comfortable even during long, hot rides. Built from durable Technomicro material and reinforced with high-grade TPU armor and a fiberglass-reinforced nylon exoskeleton, the Rex Air maintains the same trusted protection found in the original Rex. Additional features such as elastic flex zones, a nylon inner sole with removable arch support, and anti-abrasion Cambrelle lining ensure comfort without compromising durability.

A standout element of the Rex Air is SIDI’s Tecno-3 Push dial closure system, allowing precise micro-adjustments from either side for a secure, custom fit. The boot’s single ankle support brace adds critical joint stability and incorporates ventilation ports to further boost airflow. With a dual-compound sole for improved grip, a reinforced toe slider with air intake, a DuPont shift pad, and double-stitched construction in high-stress areas, every detail of the Rex Air Boot is engineered to enhance protection, control, and breathability. It’s a high-performance boot built for riders who demand safety and cooling comfort in equal measure.
