The SIDI Crossair X Boot is a pair of SIDI off-road motorcycle boots built for riders who want a lightweight, flexible feel without skipping key protective structure. Designed with MXGP and Supercross-engineered microfiber, the boot combines high-density impact protectors with ergonomic grooves intended to keep movement natural on the bike.
For control in Off-Road riding, the Crossair X Boot uses a Materiis® compound sole for grip and durability across varied terrain, plus large inner grip sections to help keep a solid connection to the bike. A fiberglass-reinforced ankle support and a 3-point anti-hyper-flexion control system round out the boot’s focus on stability and controlled range of motion.
Crossair X boots use high-density protectors that cover the boot while staying flexible, with ergonomic grooves to support movement and comfort. For added stability during landings, the ankle area is reinforced with fiberglass. A 3-point anti-hyper-flexion control system is designed to help protect against over-extension injuries, and key protection parts are replaceable to extend service life.
Closure is handled with premium nylon buckles designed for long-term use. To fine-tune fit around riding gear, the calf section is adjustable, helping riders dial in comfort and support. Together, the buckle system and calf adjustment are intended to keep the boot positioned consistently through Off-Road riding conditions.
A Materiis® compound sole, developed for Supercross competition, is used to deliver grip and durability across all terrains. Inside, large inner grip sections are designed to enhance control while riding, and the boot’s ultra-sleek inner profile aims for a snug, gap-free interface against the bike for a more connected feel.
The Crossair X Boot is built around a support-minded structure for Off-Road riding, pairing a fiberglass-reinforced ankle area with a 3-point anti-hyper-flexion control system. The goal is to help manage over-extension while keeping the boot’s overall structure lightweight and flexible. High-density impact protectors are shaped with ergonomic grooves so the protective coverage can move with the rider rather than feeling overly restrictive during active riding.

That outsole design is complemented by large inner grip sections meant to add control against the bike. The combination targets confident foot placement and steady contact in the riding positions common to Off-Road use.
