1. Introduction
Thank you for choosing Alpinestars SP-X BOA Boots. These boots are engineered for sport and sport touring riders, offering a blend of protection, comfort, and advanced features. This manual provides essential information for the proper fitting, safe use, and maintenance of your boots to ensure optimal performance and longevity.
Please read this manual thoroughly before using your boots and retain it for future reference.
2. Safety Information
Your Alpinestars SP-X BOA Boots are CE-certified, indicating they meet European safety standards for protective footwear for motorcyclists. However, no protective gear can guarantee complete protection against all injuries. Always ride responsibly and within your limits.
- Proper Fit: Ensure boots fit snugly but comfortably. An improper fit can compromise protection and comfort.
- Inspection: Before each ride, inspect your boots for any signs of damage, wear, or degradation. Do not use damaged boots.
- Cleaning & Care: Follow the maintenance instructions to preserve the protective qualities and lifespan of your boots.
- Limitations: These boots are designed for motorcycle riding. Do not modify them, as this may reduce their protective capabilities.
3. Setup & Fitting
3.1. Initial Fitting
When trying on your SP-X BOA Boots, ensure you wear the type of socks you typically use for riding. The boots should feel secure around your foot and ankle without excessive pressure points or movement.
3.2. BOA Fit System Operation
The BOA Fit System provides a precise and customizable fit:
- To Tighten: Push the dial in and turn it clockwise. Each click tightens the laces incrementally.
- To Loosen/Release: Pull the dial outwards. This will quickly release the tension in the laces, allowing for easy removal or adjustment.
- Fine-Tuning: Adjust the dial until the boots feel snug and supportive, but not uncomfortably tight.
3.3. Size Guide
To determine your correct boot size, measure the longest part of your foot in centimeters. Compare this measurement against the "SHOE INSIDE LENGTH" in the table below. Ensure your measured foot length is greater than the corresponding "COMFORT SIZE" for the chosen shoe size. If your foot length falls between the "SHOE INSIDE LENGTH" and "COMFORT SIZE" for a given column, that is your correct shoe size.

4. Usage
These boots are designed for motorcycle riding. Ensure they are properly fastened before commencing your ride. The advanced microfiber, Rideknit material, and knitted mesh construction provide flexibility and comfort, while the TPU heel counter, toe slider, and TPF Transversal Protection Frame offer protection.
- Riding Position: The boots are optimized for sport and sport touring riding positions, allowing for natural foot movement on the pegs.
- Gear Shifting: The TPU shift pad provides reinforcement for smooth gear changes.
- Walking: The asymmetric back heel design and cushioned insole enhance off-bike stability and walking comfort.
5. Maintenance
5.1. Cleaning
- Exterior: Wipe down the exterior with a damp cloth to remove dirt and debris. For stubborn stains, use a mild soap solution and a soft brush. Avoid harsh chemicals or solvents.
- Interior: Allow the interior to air out after each use. If necessary, use a specialized boot cleaner or a mild disinfectant spray.
- BOA System: Keep the BOA dial and laces free from dirt and grit. A small brush can be used to clean around the mechanism.
5.2. Drying
Allow boots to air dry naturally at room temperature. Avoid direct heat sources like radiators or direct sunlight, as this can damage materials and adhesives.
5.3. Storage
Store your boots in a cool, dry, well-ventilated area away from direct sunlight and extreme temperatures. Ensure they are clean and dry before storage.
6. Troubleshooting
- BOA System not tightening/loosening:
Ensure the dial is fully pushed in before turning to tighten. If loosening, ensure the dial is fully pulled out. Check for any debris obstructing the mechanism. If issues persist, contact Alpinestars customer support.
- Discomfort or pressure points:
Re-adjust the BOA system to achieve a more balanced fit. Ensure you are wearing appropriate riding socks. If discomfort persists, the boot size may be incorrect, or the boot may require a break-in period.
- Excessive wear on sole:
While the sole is designed for superior grip and durability, aggressive walking or dragging feet can accelerate wear. Regular inspection is recommended. Sole replacement is generally not feasible for this type of boot.
