It is designed for riders looking to restore the structural integrity and personalized fit of their footwear without needing to purchase an entirely new pair of boots.

FAQs
Are these straps compatible with Supertech R V2 or V3 models?
These straps are genuine Alpinestars replacement parts; however, compatibility can vary by specific production year. Always cross-reference your boot model with the MPN 25SLISUPT20.
Does this set include both left and right straps?
Yes, this package includes a pair of calf straps, enough to service both boots.
How often should I replace these straps?
Replacement intervals depend on frequency of use. Replace them whenever you notice fraying, cracking, or loss of closure tension.
Can I use these on non-Alpinestars boots?
No, these are proprietary components designed specifically for the construction and geometry of the Alpinestars Supertech R.
What is the best way to clean these straps?
Wipe down with a clean, damp cloth. Avoid harsh chemicals or solvents that could degrade the synthetic material.
Troubleshooting
Strap does not hold tension
Verify that the strap is threaded correctly through the buckle or closure mechanism and check for debris inside the housing.
Difficulty inserting the new strap
Ensure the boot is unfastened completely; use a small amount of silicone lubricant if the strap is binding against the guide channel.

Setup, Compatibility & Care
To install your new calf straps, simply slide the old strap out of the mounting channel on the boot and thread the new one through, ensuring the teeth or adjustment mechanism faces the correct direction as per your original configuration. These straps are exclusively designed for the Alpinestars Supertech R series (Model MPN: 25SLISUPT20). To maximize the lifespan of your replacement straps, clean them regularly with a damp cloth to remove track grit and debris, and avoid over-stretching the material when adjusting the fit while the boots are on your feet.
