This motocross boot is constructed from an innovative microfiber material that is flexible and abrasion-resistant. The upper material is reinforced with PU (Polyurethane) for high levels of water resistance, durability, and improved weight-saving performance. This material ensures a consistent fit even for long-term usage and is easy to maintain and clean.

The internal lining includes anti-slip microfiber suede on the heel to help keep the foot in position. An extended microfiber gaiter helps prevent excessive water and dirt entry. The shell is highly resistant to abrasion and impact, adding to the boot's overall durability and improving its streamlining.

Soft foam reinforcement on the ankles and collar provides long-lasting comfort and shock absorption. The high-strength sole construction offers durability and protective performance. The dual-compound, removable anatomic footbed includes EVA (Ethylene Vinyl Acetate) and Lycra top for comfort and support, ensuring even weight distribution and a reinforced heel.

The TPU (Thermoplastic Polyurethane) ankle protection system incorporates a biomechanical link between the middle and bottom sections of the boot, helping prevent damage to the leg by providing progressive force relief for torsional forces. Alpinestars has developed a TPU shin plate and medial protection, constructed from a single part for greater structural integrity and stability.

The anatomically profiled shin plate features a dual closure system with an internal microfiber flap attached with a buckle closure. This new TPU ankle protection system helps prevent damage to the leg by incorporating a biomechanical link between the middle and bottom sections of the boot, providing progressive force relief for torsional forces.
