Overview
Sidi Rex Air
The Sidi Rex Air is pure Italian racing technology dedicated to airflow.
The Ventilation King
The “Air” isn’t marketing—the entire upper is perforated Technomicro material. It flows massive amounts of air, keeping feet cool during intense track sessions or hot summer rides.
Techno-3 Push System
Forget zippers and velcro. The Rex uses three steel cable winches:
- Shin Tensioner: Secures the top.
- Ankle Support: Locks the heel in place.
- Instep Adjuster: Customizes the fit over the arch.
This ensures a glove-like fit that doesn’t loosen over time.
Ankle Support Brace
The robust external resin structure limits lateral movement (twisting) while allowing front-to-back flexibility for shifting and braking.
Replaceable Everything
Sidi boots are an investment. Almost every part of the Rex is replaceable:
- Toe sliders
- Shin plates
- Fasteners
- Heel cups
If you ride hard in hot weather, there is no better boot. The mechanical closure is a masterpiece of engineering.
