The Alpinestars Supertech R Calf Strap is an essential maintenance accessory designed for owners of Supertech R motorcycle boots who require a secure, reliable closure system. It serves as a direct replacement part to restore the intended fit and safety integrity of the boot's calf area, ensuring the gear performs as expected during high-performance riding. While this product is a perfect functional match for the specified boot series, users should note that it is model-specific and will not be compatible with other boot lines in the Alpinestars collection.

These straps are designed for the Supertech R line; please consult your specific boot's manual or product code to ensure exact generation compatibility.
The product is supplied as a pair, allowing you to replace the straps on both the left and right boots simultaneously.
No, the straps are designed for tool-free installation by sliding them into the existing boot housing.
They are made from high-durability, weather-resistant synthetic polymers designed for the demanding environment of motorcycle racing.
Replace them whenever you notice the tension failing, the teeth becoming rounded, or physical fraying of the material.
Ensure the track is clear of dirt and debris, then verify the strap is inserted in the correct orientation.
Apply a very light amount of silicone-based lubricant to the edges of the strap to reduce friction during installation.
Installation of the calf straps involves carefully threading the new straps through the existing retention housing on the back of the Supertech R boot.
Compatibility is strictly limited to the Alpinestars Supertech R series. To care for your straps, rinse them with fresh water after riding in muddy or dusty conditions to prevent debris from grinding down the fastening teeth. Periodically inspect the strap surface for signs of fraying or fatigue to ensure they remain safe for track use.
